Hoo 164 Posted May 17 The F1 series of games support the output of certain game data across UDP connections. This data can be used supply race information to external applications, or to drive certain hardware (e.g. motion platforms, force feedback steering wheels and LED devices). The following information summarises these data structures so that developers of supporting hardware or software are able to configure these to work correctly with the F1 game. If you cannot find the information that you require, or spot any issues with this specification then please let us know below. Packet Information Packet Types Each packet can now carry different types of data rather than having one packet which contains everything. A header has been added to each packet as well so that versioning can be tracked and it will be easier for applications to check they are interpreting the incoming data in the correct way. Please note that all values are encoded using Little Endian format. All data is packed. The following data types are used in the structures: Type Description uint8 Unsigned 8-bit integer int8 Signed 8-bit integer uint16 Unsigned 16-bit integer int16 Signed 16-bit integer float Floating point (32-bit) uint64 Unsigned 64-bit integer Packet Header Each packet has the following header: struct PacketHeader { uint16 m_packetFormat; // 2020 uint8 m_gameMajorVersion; // Game major version - "X.00" uint8 m_gameMinorVersion; // Game minor version - "1.XX" uint8 m_packetVersion; // Version of this packet type, all start from 1 uint8 m_packetId; // Identifier for the packet type, see below uint64 m_sessionUID; // Unique identifier for the session float m_sessionTime; // Session timestamp uint32 m_frameIdentifier; // Identifier for the frame the data was retrieved on uint8 m_playerCarIndex; // Index of player's car in the array // ADDED IN BETA 2: uint8 m_secondaryPlayerCarIndex; // Index of secondary player's car in the array (splitscreen) // 255 if no second player }; Packet IDs The packets IDs are as follows: Packet Name Value Description Motion 0 Contains all motion data for player’s car – only sent while player is in control Session 1 Data about the session – track, time left Lap Data 2 Data about all the lap times of cars in the session Event 3 Various notable events that happen during a session Participants 4 List of participants in the session, mostly relevant for multiplayer Car Setups 5 Packet detailing car setups for cars in the race Car Telemetry 6 Telemetry data for all cars Car Status 7 Status data for all cars such as damage Final Classification 8 Final classification confirmation at the end of a race Lobby Info 9 Information about players in a multiplayer lobby Motion Packet The motion packet gives physics data for all the cars being driven. There is additional data for the car being driven with the goal of being able to drive a motion platform setup. N.B. For the normalised vectors below, to convert to float values divide by 32767.0f – 16-bit signed values are used to pack the data and on the assumption that direction values are always between -1.0f and 1.0f.

Hoo 164 Posted May 17 (edited) FAQS How do I enable the UDP Telemetry Output? In F1 2020, UDP telemetry output is controlled via the in-game menus. To enable this, enter the options menu from the main menu (triangle / Y), then enter the settings menu - the UDP option will be at the bottom of the list. From there you will be able to enable / disable the UDP output, configure the IP address and port for the receiving application, toggle broadcast mode and set the send rate. Broadcast mode transmits the data across the network subnet to allow multiple devices on the same subnet to be able to receive this information. When using broadcast mode it is not necessary to set a target IP address, just a target port for applications to listen on. Advanced PC Users: You can additionally edit the game’s configuration XML file to configure UDP output. The file is located here (after an initial boot of the game): ...\Documents\My Games\<game_folder>\hardwaresettings\hardware_settings_config.xml You should see the tag: <motion> ... <udp enabled="false" broadcast=”false” ip="127.0.0.1" port="20777" sendRate=”20” format=”2020” yourTelemetry=”restricted” /> ... </motion> Here you can set the values manually. Note that any changes made within the game when it is running will overwrite any changes made manually. Note the enabled flag is now a state. What has changed since last year? F1 2020 sees the following changes to the UDP specification: Penalties have been added as a new Event Type Weather forecast data is now available in session packets for upcoming sessions Reduced the size of the surface and inner tyre temperature fields in the Car Telemetry to reduce overall packet size as more vehicles need to be added My Team allows an extra team to race – this means that all the places in the packets where 20 cars were used, 22 are now needed. N.B. this will not be fixed in old formats (2019, 2018, legacy) – if you are in the “My Team” career mode with any format other than 2020 specified, no data will be output. All other game modes will function as before Added Vietnamese and Barbadian nationalities Added Final Classification packet for end of race results Made m_gridPosition the actual numerical position, not 0-based (only in 2020 data) Added Lobby Info packet to send data to UDP when in a multiplayer lobby Added number of laps the current set of tyres have been used for in status packet Split the tyre pressures in Car Setups packet into RL, RR, FL, FR to reflect the game changes Added secondary player car index to packet headers for splitscreen Added MFD Panel Index to the car telemetry packet for both players Added best sector times and lap numbers to the laps packet as they cannot always be recorded correctly (e.g. fast-forwarding time) – N.B. the order has been slightly rearranged to tidy up Changed all sector times in lap data packet to be in milliseconds (uint16 instead of float) to reduce packet size so other things can be added Added indicator for DRS faults to the car status packet Updated ERS mode values Speed trap triggered event added Added DRS activation distance to indicate whether the car has passed detection and DRS will be available in the subsequent activation zone Suggested gear added to the car telemetry packet What is the order of the wheel arrays? All wheel arrays are in the following order: 0 – Rear Left (RL) 1 – Rear Right (RR) 2 – Front Left (FL) 3 – Front Right (FR) Do the vehicle indices change? During a session, each car is assigned a vehicle index. This will not change throughout the session and all the arrays that are sent use this vehicle index to dereference the correct piece of data. What encoding format is used? All values are encoded using Little Endian format. Are the data structures packed? Yes, all data is packed, there is no padding used. Will there always be 20 cars in the data structures? No, for F1 2020, there is a new feature called “My Team” which allows an extra team to be present on the grid. This means that all previous places where 20 cars were used, 22 is now the maximum. If “My Team” is not active however, most games modes will act as before and have a maximum of 20. Note that if your UDP format is 2019, 2018 or legacy and you are in “My Team” career mode, no UDP output will be produced because of this imitation. There is still the data item called m_numActiveCars in the participants packet which tells you how many cars are active in the race. However, you should check the individual result status of each car in the lap data to see if that car is actively providing data. If it is not “Invalid” or “Inactive” then the corresponding vehicle index has valid data. How often are updated packets sent? For the packets which get updated at “Rate as specified in the menus” you can be guaranteed that on the frame that these get sent they will all get sent together and will never be separated across frames. This of course relies on the reliability of your network as to whether they are received correctly as everything is sent via UDP. Other packets that get sent at specific rates can arrive on any frame. If you are connected to the game when it starts transmitting the first frame will contain the following information to help initialise data structures on the receiving application: Packets sent on Frame 1: (All packets sent on this frame have “Session timestamp” 0.000) Session Participants Car Setups Lap Data Motion Data Car Telemetry Car Status As an example, assuming that you are running at 60Hz with 60Hz update rate selected in the menus then you would expect to see the following packets and timestamps: Packets sent on Frame 2: (All packets sent on this frame have “Session timestamp” 0.016) Lap Data Motion Data Car Telemetry Car Status … Packets sent on Frame 31: (All packets sent on this frame have “Session timestamp” 0.5) Session (since 2 updates per second) Car Setups (since 2 updates per second) Lap Data Motion Data Car Telemetry Car Status Will my old app still work with F1 2020? F1 2020 uses a new format for the UDP data. However, earlier formats of the data are still supported so that most older apps implemented using the previous data formats should work with little or no change from the developer. To use the old formats, please enter the UDP options menu and set “UDP Format” to either “F1 2019”, “F1 2018” or “Legacy” (for F1 2017 and earlier). Specifications for the legacy format can be seen here: http://forums.codemasters.com/discussion/53139/f1-2017-d-box-and-udp-output-specification/p1. Specifications for the F1 2018 format can be seen here: https://forums.codemasters.com/topic/30601-f1-2018-udp-specification/. How do I enable D-BOX output? D-BOX output is currently supported on the PC platform. In F1 2020, the D-BOX activation can be controlled via the menus. Navigate to Game Options->Settings->UDP Telemetry Settings->D-BOX to activate this on your system. Advanced PC Users: It is possible to control D-BOX by editing the games’ configuration XML file. The file is located here (after an initial boot of the game): ...\Documents\My Games\<game_folder>\hardwaresettings\hardware_settings_config.xml You should see the tag: <motion> <dbox enabled="false" /> … </motion> Set the “enabled” value to “true” to allow the game to output to your D-BOX motion platform. Note that any changes made within the game when it is running will overwrite any changes made manually. How can I disable in-game support for LED device? The F1 game has native support for some of the basic features supported by some external LED devices, such as the Leo Bodnar SLI Pro and the Fanatec steering wheels. To avoid conflicts between Codemasters’ implementation and any third-party device managers on the PC platform it may be necessary to disable the native support. This is done using the following led_display flags in the hardware_settings_config.xml. The file is located here (after an initial boot of the game): ...\Documents\My Games\<game_folder>\hardwaresettings\hardware_settings_config.xml The flags to enabled/disable LED output are: <led_display fanatecNativeSupport="true" sliProNativeSupport="true" /> The sliProNativeSupport flag controls the output to SLI Pro devices. The fanatecNativeSupport flag controls the output to Fanatec (and some related) steering wheel LEDs. Set the values for any of these to “false” to disable them and avoid conflicts with your own device manager. Please note there is an additional flag to manually control the LED brightness on the SLI Pro: <led_display sliProForceBrightness="127" /> This option (using value in the range 0-255) will be ignored when setting the sliProNativeSupport flag to “false”. Also note it is now possible to edit these values on the fly via the Game Options->Settings->UDP Telemetry Settings menu. Can I configure the UDP output using an XML File? PC users can edit the game’s configuration XML file to configure UDP output. The file is located here (after an initial boot of the game): ...\Documents\My Games\<game_folder>\hardwaresettings\hardware_settings_config.xml You should see the tag: <motion> ... <udp enabled="false" broadcast=”false” ip="127.0.0.1" port="20777" sendRate=”20” format=”2020” yourTelemetry="restricted" /> ... </motion> Here you can set the values manually. Note that any changes made within the game when it is running will overwrite any changes made manually.

Hoo 164 Posted May 20 1 hour ago, Drospy said: Hi, is there any possibility to have "DELTA TIME" in UDP telemetry ? Thank you Walter This isn't something we plan on doing as delta time implementation is a design choice that involves specific logic to evaluate rather than an objective piece of real-time data. There are too many different approaches to this to give a "correct" delta, so we will simply provide the time and positional data for the cars and app developers can work out how they want to interpret this.

Now, calculate delta time between sector time and best time for sector. I think that this is a good info. However, this doesn't work in Time Trial, because we don't have best time for sector Share this post Link to post Share on other sites

cjorgens79 3 Posted May 21 Just a minor point, I have been doing some api testing and have noticed that the two extra slots (21, 22) have randomish values in them for some fields that could make it a little confusing for some people working with the api. For example, the api is reporting 20 cars in the race (as expected), however slot 21 has semi valid x,z positional data, race position is 1 and lap number is 1. Slot 22 has no positional data, its race position is 0, but it is on lap 1. It would be nice if these slots could be cleared (zeroed out) properly so there is no randomish data in them to make it clearer for integrators when dealing with the telemetry data.

Oasis81 4 Posted May 22 (edited) HI same 2019 the data stops before the finish time in Q. is it possible to extend the data sent until all the cars have finish the session? second and most important thing for me: the sectors: in the 2019 the sectors are erased after the lap, because at the new sector 1 in the new lap overwrite the sector 1 of the last lap. this happen in every case, if the next lap is the pit entry or if it's a worst lap than the previous. is it possible that the new sector overwrite the old sector only if the new lap is better than the previous?

Hi @Oasis81, In single player mode the session ends once the player has finished their session, so the UDP data simply reflects what the game is doing. If the game were to allow the session to continue and the player to spectate for the rest of the session (like it does in multiplayer) then this should just work in the UDP data. However, this is a bigger feature request that is beyond the scope of the UDP telemetry data. I can pass the suggestion back to the team if that is what you are proposing. For the second point, the LapData packet currently keeps only the latest sector information. These times can obviously be stored by your app if needed. Are you suggesting that we should add a set of "best sector" times into the LapData packet? Thanks, Hoo. Share this post Link to post Share on other sites

Are you suggesting that we should add a set of "best sector" times into the LapData packet? Thanks, Hoo. Hello Hoo thanks for the answer. For the first point yes, the data stops when the player ends the Q. but usually there are some cars in the track that have no finisched their laps, and this could be modify the classify. My suggestion is the choice to the player to stops immediatly the Q same as now, or to choose to continue to follow the Q in spectator mode same as multy, until all the cars are over the Q time, to have the UDP data also for this time left. it will be also more realistic, because maybe in the Q I have the pole position, but when the Q finished at the next screen I'll see that i'v lost it, but I couldn't followed this in real time. for my view. For the second point. My app atm works same as this: every car has a personal list of record that stores every sector and every lap, order the list with the better lap and select the first record. , after this match this data with other list with other cars time and export the classify. this data can be stored only in real time mode, ex: car 1 | lap 3 | time 3 | sect 1.3 | sect 2.3 | sect 3.3 car 1 | lap 2 | time 2 | sect 1.2 | sect 2.2 | sect 3.2 car 1 | lap 1 | time 1 | sect 1.1 | sect 2.1 | sect 3.1 ------------------------------------------------- car 2 | lap 2 | time 2 | sect 1.2 | sect 2.2 | sect 3.2 car 2 | lap 1 | time 1 | sect 1.1 | sect 2.1 | sect 3.1 -------------------------------------------------------- Class car 1 | time 3 | sect 1.3 | sect 2.3 | sect 3.3 car 2 |time 2 | sect 1.2 | sect 2.2 | sect 3.2 ecc... but this has 1 big problem: 1) if the player skip something, same as the pit exit or the return to the box or i FFW the time and other cars are on track and does their laps, , the data sent from the game about the sectors could be skipped, so i can't store it. so, my suggestion is STORE the Table that the player seen on the monitor when is at the box , where is all the cars with their better time and the respective sectors. because the game can store this data in some way, also if i skip something or FFW the time, but i can't. I can suggest something like this: m_bestlap (there is) m_bestlapSector1 m_bestlapSector2 m_bestlapSector3 or only sect 1 and 2 could be fine. I don't know if it's clear 😄 thanks regards Edited May 22 by Oasis81 1 Share this post Link to post Share on other sites
cjorgens79 3 Posted May 23 @Hoo The LapData packet has some anomalous data in it. This is the current state of drivers 6 seconds into a 30 minute practice session. Note that the Lap Distance and Total Distance values are large negatives. I would have expected these to be 0, as the session has just started and each driver is in the garage. The Pit Status also seems a bit random too, again everyone is in the garage however the pit status seems random between them. The very first LapData packet of the session looks exactly the same as well.

I think this could be useful as well for those single player sessions where time jumps occur by going back to garage or jumping to a flying lap.

And the Trash in "unused" cars is also, what has been there at least in time trial and online races. If it doesn't get fixed/changed, then you have to massage the data yourself. That is what I have been doing with earlier games. I.e. by using the sResultStatus <= 1 to detect, if the driver is active and then modify inactive's values accordingly so they don't mess with the proper data. The issue I see with the zeroing to"0" the values is that there is DriverID 0 for Carlos Sainz, so if they "0" all data, you still have the issue if the driver is "inactive" or if it is Sainz. I would prefer they change the Sainz driverId to something else. Would make many things easier. I still need to do more driving and looking at the data to see, if there is anything odd/new going on this year. Thus far (some 3 hours of driving + some 15 hours or running save data feed on my tool), haven't noticed anything too critical. Share this post Link to post Share on other sites
BernoAU 2 Posted May 24 It would be great if the LapData struct included a time gap to the car ahead. All we need is the gap to car ahead as obviously the gap to car behind is the car ahead gap of the next position down. Also if we want to show the gap to the leader we can simply add up all the gaps ahead. We also already have the current lap number so can calculate if a car is a lap down. So we could replicate the leaderboard with time gaps with just one extra float per driver in the struct. Share this post Link to post Share on other sites

Thanks for the reply, after I posted it occurred to me that was probably the reason why the distances were negative. The pit status is a bug though as you have mentioned, it is easy enough to work around though. Re the "zero" stuff, yeah i know what you mean about the conflicting ids, however the result status field's intention is to indicate whether or not the driver slot has valid data or not, if it is not a valid driver then any data in that driver's packet should be ignored. I found this flag after that original post, however i still think it is cleaner for the unused slots to be zeroed out. Share this post Link to post Share on other sites

I’m currently doing my own calculations to arrive at the time gaps which is OK, but direct data from the game would be much better and more accurate. On a different note, it’d be nice to be able to know if DRS was going to be available soon, ie. the detection line has been crossed and will be available in the DRS zone. As far as I can tell this isn’t covered. Share this post Link to post Share on other sites
Oasis81 4 Posted May 25 (edited) a question it's only mine problem or there is an error when you go on Q2 about the data? the car with index 15 has CarPosition at 1, and my app generate errors because there are 2 cars with CarPosition at 1., the first and the 15 the problem is that the car is inactive because in the Q2 the Car 15 is out of qualify, so, sam as other cars under it, the car position should be 0, not 1. with f1 2019 I haven't this problem. edit: after some checks i see that the first car out of range (15 in Q2) ... 11 in Q3 ... 21 in Race has always Car position at 1, and not at 0.

Check the m_resultStatus field, its intention is to indicate whether or not the driver slot has valid data or not, if it is not a valid driver then any data in that driver's packet should be ignored. So basically ignore any drivers who's m_resultStatus value is less than 2. Share this post Link to post Share on other sites

HI Yes I must use that field now, the problem i that i must rewrite more and more part of the app because the packet comes with all the data, and without that carposition for invalid cars it was more easy to do, without filtering before.

Hoo 164 Posted May 26 Thanks for all of the feedback so far everyone. We're looking into some of these issues now. In terms of delta times, we're not considering adding this in at the moment as the data should exist for everyone to do what they need. As stated above, delta time has so many different approaches and uses that it isn't something that we can add in to accommodate everyone's own use case. For example, there have been requests for the gap to the car in front, pitting delta, realtime delta used in Time Trial. Even something a simple as gap to the car in front comes with lots of design interpretation to make it work correctly: If we simply work out the gap time gap between each car passing the specified point in the circuit, how do we interpolate between differences in track position reported by the car as these don't usually align? What happens when cars enter the pit lane or go off track? Do we consider using predictive deltas, or based them retrospectively on cars passing the same point in the track? What happens if you are not racing the car in front due to lapping them or alternative pitting strategies? What happens if cars are on in-laps or out-laps? ... and so on. The game already uses a few different approaches to delta times and even more have been suggested by the community. As each one is a subjective design choice, we prefer to just provide the lap and time data and let you all choose how to use this. We'll provide an update on the various changes and bug fixes ahead of the next beta phase. Thanks. 2 Share this post Link to post Share on other sites
LonelyRacer 8 Posted May 26 On the topic of Delta. Just wanted to share this, as I see so many people asking about the Delta. And I know there are few ways to do this. I used to calculate the delta as an estimate based on average speed and distances between the cars. Wasn't very good. I know that some people store only leaders time and position and calculate the delta from that. This is pretty easy way to get the deltas. My solution This is what I have done in my tool: https://www.racedepartment.com/downloads/telemetry-application.27456/ The users can set the accuracy, basically the distance between detection points. Range is from 1m to 500m. At the start of the race, I create an empty matrix, where each cell will contain <driverId, totalTime>. i.e. DeltaItem[columns][cars]. The width of the matrix (i.e. columns of the matrix) is: totalLapsInRace * trackLength / accuracyDistance. For 5 lap race in 5k track with 100m accuracy the matrix width is 250 columns. With 20 cars, it means 5000 cells, each containing an int and float, so approx 50kb of memory. For a 70lap race in 5k track with 1m accuracy, memory used is about 70mb. For 10 hour endurance with 60 cars (in ACC), this would be around .3gb, but there e.g. 200m accuracy is more than sufficient, which takes about 1.5mb to store the whole 10h race. At the start, the first column contains the situation at the start of the race. (totalDistanceDriven <= 0). The index for each column after start is easily calculated with floor(totalDistanceDriven / accuracyDistance) + 1. So if accuracy is 50, you have driven 225, then the column is 5. As the race commences and cars pass to the new "column", I store the leader to the top of the column and cars behind to lower positions, i.e. each column then contains from the top down the track positions at that point during the race. All cells in that column contain the driverId + totalTime at that point. Note, all times use the totalTime, you can get that .e.g from the header's sessionTime. So then when I calculate delta to the leader for certain car, I take their totalDistanceDriven, find the column. In that column I take their cell (based on driverId), then deduct from the total time the leaders total time (at row 0). This is the delta to the leader. E.g. leader entered column 6 at 17.1 and you entered there at 17.8, so delta is .7. Delta to the car in front you get by finding the cars column (with totalDistanceDriven) + row (based on driverId), then calculating the totalTime diff for the row and row - 1. So you entered at column 6, your total time entering the range was 17.8. The car in front (your row - 1) entered the column at 17.6, so the delta to front is .2. Delta to the car behind is similar, you just find the totalDistanceDriven for car behind, their correct column and then calculate the time difference to your cell on that column. The car behind is at column 5. Your time entering that range was 17.1 and the car behind entered at 17.5, so the delta to back is .4 Getting the data is pretty fast, as calls are direct array calls with index. The only small exception is to find the row, you compare with, which needs extra loop to find the right row with corresponding driverId, but in average it is MAX_CARS/2, so with F1 series about 10 extra calls per search. But if you really need to optimize that too, you could store for the columnsr a hashmap<driverId, index_in_that_column> to reduce this search also to a single call, but at a cost of memory (columns * hashmap size) One optimization one could do, is to store the data at the "game" order, i..e car at index 0 is stored at row 0 and so on. With F1 series this should be ok, as the order stays same during the race, but there are other games, where the "game order" changes, as people join/drop. This optimization would take away the driverId search mentioned above. Other optimization for a dash solution would be to store only 4 rows, 1 for leader, 1 for car in front, 1 for the player and 1 for the car behind. Then you would always have leader at row 0, person in front (at that point) at row 1, the player in row 2 and the car behind in row 3. So the "id checking" would go away, but you would still know, who is in front/behind, if you save the driverId on the cells. And you would have access to the delta history to leader for the player. For 70lap on 6k track with 1m accuracy takes about 17mb. With this implementation, during the race and/or at the end of the race, I can produce a chart like this. Cheers.

Ok, all right, just a request: In Time Trial there isn't data of bestlap, only best lap time, I ask to add SectorTime data of best lap.
