Faya 1,188 Posted June 20, 2019 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 summarise this 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 then please contact community@codemasters.com and a member of the dev team will respond to your query as soon as possible. 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; // 2019 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 uint m_frameIdentifier; // Identifier for the frame the data was retrieved on uint8 m_playerCarIndex; // Index of player's car in the array }; 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 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.

Faya 1,188 Posted June 20, 2019 FAQS How do I enable the UDP Telemetry Output? In F1 2019, 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=”2019” 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 2019 sees the following changes to the UDP specification: Updated driver list and included F2 drivers Added terrain tyre contact type to motion packet Removed exhaust damage Added game version to packet header Renamed num cars to num active cars Increased accuracy of steering, brakes and accelerator values Added new event types Added visual tyre compound to deal with new F1 tyres Added fuel remaining in laps – value on MFD Added restrictions to sensitive data via “Your Telemetry” setting 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? Most structures contain 20 cars – this is the maximum that can be in a race in the game. There is a 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 2019? F1 2019 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 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: How do I enable D-BOX output? D-BOX output is currently supported on the PC platform. In F1 2019, 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=”2019” /> ... </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. Share this post Link to post Share on other sites

Bannish 3 Posted June 21, 2019 I have one question regarding the surface type. When is the surface type set to 8 (water)? As soon as there is standing water on the track or does that not affect the surface type field? Share this post Link to post Share on other sites

Oasis81 1 Posted June 23, 2019 HI The Sectors in the laptime, for every cars, are stored this year or not? in the 2018 I had to save it everytime because after the lap they disappeared, and it was not so simple it will be good if every laptime in Q and Race are saved with their sector time... or stored when the lap is complete and overwrite in the new lap.

rafitagd 2 Posted June 23, 2019 @Retornik there is a "special" version of the game (press version) which codemasters give access to for some people (brand ambassadors, YouTubers,known people in sim racing etc.) Normally those persons get a copy of the game like a month before lunch. They can't post anything (prohibited) about the game for a time. But usually week or two before release the game developer allows this users to start posting info and videos about the game. For F1 2019 was last Friday, so since last Friday all people with this press game version where allowed by codemasters to share all type of media about the game. This is an usual procedure with any game. And thanks Codemasters to share the new specs before release for us devs to be able to have our apps ready for release day!

LonelyRacer 5 Posted June 25, 2019 @Hoo, Any change, that at some upcoming patches, the PacketEventData could send the DRS status (DRSD or DRSE) after the SSTA? Now as I understand the situation, DRS is available on all other modes, except at Race Start. And in P/Q, if it rains, it should be disabled. Now it seems, the DRS is available in Practice even if it rains. If you want to display the correct start of session DRSD/DRSE status in a tool, getting the DRSD / DRSE after SSTA would make things much easier. Cheers, Share this post Link to post Share on other sites

If you want to display the correct start of session DRSD/DRSE status in a tool, getting the DRSD / DRSE after SSTA would make things much easier. Cheers, Hi, I've checked the DRS here and it seems to be correctly disabled when in light or heavy rain during practice sessions. If it is very light rain then DRS will still be allowed, so please check whether it has hit the "light rain" threshold. Let us know if you are still seeing issues an we'll take another look. The DRS events (DRSD / DRDE) should be triggering correctly when there is a change in status during the race. If DRS is permitted from the start of the session then it should already be set to enabled. Trying to send this message after the race start could get messy as the game would end up sending out a bunch of session info after the race has actually started. We'd prefer to avoid changing the timing of this unless it is causing you major problems. If you are noticing the DRS-related messages triggering incorrectly then please let us know and we'll take a look. Thanks, Hoo. Share this post Link to post Share on other sites
navarreitor 2 Posted June 25, 2019 (edited) @Hoo @Faya I have a PS4 copy and I can't find where the Restricted/public telemetry data option is. I hope on PS4 we can make this data public because for commentators all this info is very useful. In fact, it would be fabulous if in the menus of the leagues it could be restricted to be public, just as the assistance that can be used in the races can be restricted when you create the league. In all the competitions in which I participate, we use models that I have provided to have that information to commentators and viewers of the races on youtube/twitch (links below) Edited June 25, 2019 by navarreitor Share this post Link to post Share on other sites

This option should be available in our next game update (v1.04). The intention is for leagues to manage the setting of the restricted flag with their members directly. The game will not override users' privacy settings based on game mode. If this causes too many issues with league management then let us know and we will see if there are any alternative approaches that we can take. Thanks, Hoo.

Thank you @Hoo We can ask our participants to do public their data but would be better if we can manage that form the admin/owner menu. If not, it is possible that some pilot forget to put his data public and the only solution we would have is to sanction them. BTW, League mode is great, but it would be best if it has a fourth profile as a guest (as well as owner, administrator, and participant). That way, when not all the participants can run a race, instead of AI, they could be replaced by guest pilots for a grand prize. The AI is fine, but nothing like the human touch. Another subject, it would be possible that "Stop and go" penalties sums in the penalties of a player until they are fulfilled? Thank you again Edited June 25, 2019 by navarreitor Share this post Link to post Share on other sites

Oasis81 1 Posted July 1, 2019 (edited) I really don't understand why you don't storage the sector! in the packetlapdata only the bestlap is stored, the sector is always resetted. but in the table during the Q every bestlap has is sector I'done a lot of work for find a way to store the sector for every bestlap for every driver, but if i FFw the time obviously i lost that info. if i come back to garage directly the time has a jump and i lost the info if some driver does his best lap. why?! wehre are that info?!

You are right using structs and you are right using StructLayout, this way your structs will get populated with correct data from data packet, as long as the order of the fields is the same, since C# use the data type of the field to know how many bits should take from data packet for each field... But YOU HAVE TO BE SURE, the order of your fields/props doesn't change/is the same as Codies posted... if it changes you will get "corrupted" data... Share this post Link to post Share on other sites

Thank you in advance Welcome to programming, you’ve picked a tough project to start with but it sounds like you’re going well. Unsigned 16 bit number is a value between 0 and 65535 so 32 isn’t wrong. Also, I’ve noticed that the brake temps seem to come through as 32 at the start of a session so I think if you wait a bit longer you’ll get the full values correctly. In terms of the multi-value aspect, this just means it’s an array of 4 items which starts at 0; so you can access each item by using m_brakesTemperature[0], m_brakesTemperature[1], etc. Hope this helps. 1 Share this post Link to post Share on other sites
thetravisty 0 Posted July 8, 2019 @DaveyGravy Thank you for that information. Ive been able to get more data from the packets because of it. Now I need to figure out why the engine temp is always 89.... Im actually an ex-programmer but I mostly worked in .net - I never came across structs and udp during that time.
