Administrator Popular Post BarryBL 8,361 Posted July 8 Administrator Popular Post Share Posted July 8 Here is the latest specification for the UDP telemetry system for F1 2021. Please note that we've opted for posting a document with this info rather than adding this into the forum as this is easier to work with. The spec should be downloaded from here: Data_Output_from_F1_2021#51.docx Below is a summary of the various updates and bug fixes added to this year's game. A big thanks to everyone who has contributed suggestions and reported bugs with system over the past year, plus an extra shout out to the beta group who helped test this out ahead of release. Fixed Pre-Release Add number of warnings in a lap into LapData packet => We have added the number of warnings a driver has to the lap data Add a means of detecting when a stop-go penalty has been served => We have added an event which fires when stop go and drive through penalties have been served Add a way of indicating when a player is in a paused state => This will trigger after 3 seconds of being paused in an online race Add a means of detecting frames being replayed due to flashbacks => We have added a new flashback event that gives enough info to work this out Update UDP to include new Unreliable Weather Forecasts feature => Done Add engine wear/damage to the telemetry output => Done Add info to show which rev lights are illuminated => Done Add new damage parts to the data => Added floor, diffuser and sidepod damage Add the driver number to UDP output within the lobby => Done Tyre wear values should be floats not ints => Done Driver IDs are now conflicting => We have added a new network Id so that we don't need to offset by 100 now Traction Control is only showing values of 0 or 2 => This was working, but not shown in the docs. These have been update now Time for ghost cars are not displayed in telemetry output => Re-enabled now No enum value 0 => We have now made the values 255 for invalid items Provide information about all assists used => We have added Steering, Braking, Gearbox, Pit, Pit Release, ERS & DRS Add AI difficulty information => Done Add identifier to link all sessions within a race weekend => Done Add identifier to link all sessions within a career season => Done Add an identifier to link restarts of the same (offline) session => Done Add lap and sector info for the previous lap => We have added a new Session History packet which gives a list of all the laps in the session Add info for pit stop strategy / windows => Pit window and rejoin position info added to the data Show number of pit stops taken => Done Show tyres used in session history => We have added a new Session History packet which gives a list of all the tyre stints in the session Add data to show status of start light sequence => We have added "Start lights" and "Lights out" events to the UDP Set m_tyreAgeLaps as public => We have removed the tyres age from the restricted list Add the PIT stop time => We have added pit timings for all vehicles Add number of warnings in a lap into LapData packet => We have added the number of warnings a driver has to the lap data Add a means of detecting when a stop-go penalty has been served => We have added an event which fires when stop go and drive through penalties have been served Add a way of indicating when a player is in a paused state => This will trigger after 3 seconds of being paused in an online race Add a means of detecting frames being replayed due to flashbacks => We have added a new flashback event that gives enough info to work this out Add DRL assist info into SessionData packet => this has now been added Convert all time-based units to the same type and unit => time-based units will use milliseconds as ints where possible (note the a few of these still work in seconds and total lap time is a double). Please let us know if there are any issues or changes needed to this. Wear data is not updating in solo play => we tested this one and think it should be working as expected. Let us know if you are still having issues Add an invalid lap flag to LapHistoryData => added the invalid lap, together with the sector validity as well which gives a bit more information. m_buttonStatus bits for L2 and R2 are over-written if using steering wheel Send PacketCarTelemetryData and m_buttonStatus data after race has ended Unable to retrieve LapHistoryData for the final lap Fixed in Future Patch Release (date tbc) Add extra byte to indicate if this is the final packet in a batch => we didn’t want to change the packet structure at this stage, so instead have made a change so that the final session history packets are sent AFTER the final classification packet, so if you watch for the session ended packet. This change is expected in a future patch of the game. Incorrect number of laps reported in Final Classification info => fixed and due for release in a future patch m_resultStatus shows as "active" after the race has finished LapHistoryData is not sent for an active car following retirement of another car => we will now update this data for all cars, even if they are retired Still Open Session History info from previous session is sent following a restart Refresh rate requires "hz" suffix Some values not updating on the correct frame when crossing lap boundary No way of linking player data using m_name => This is an old request. We are working with our legal teams to find a way of providing this functionality in the future Won’t Fix Sum of sector times don't match total lap time in SessionHistory data => we believe this is a result of rounding / precision issues. The current UDP data for SessionHistory matches our in-game lap time UI output, so we will leave this as it is for the time being. We have a task on our backlog to investigate these precision issues in the future. Add lap tyre info into the final classification packet for the best lap => would require a change to the format which we don’t want to do now, so we’ll look at this for a future project Consider moving assistOn packets to the PacketLobbyInfoData => this is not really possible to support due to how the network game works. If you see any instances of assist restrictions not working then please let us know. Add time delta to car in front and behind => This is an old request. As previously stated, players have enough data to produce their own delta time system so we will not be implementing this Inlap times are not displayed in the telemetry output => We are unable to accommodate this request the behaviour is based on how the game handles inlaps and outlaps. We can't provide the requested functionality without re-writing much of the game logic in this area (which we aren't able to do). Driver number does not update when taking control of a vehicle => We are unable to fix this as driver customisations are handled when first launching a session and do not get updated when players drop into a race mid-session. Increment laps to accommodate outlaps and inlaps => We are unable to accommodate this request the behaviour is based on how the game handles inlaps and outlaps. We can't provide the requested functionality without re-writing much of the game logic in this area (which we aren't able to do). Increase the number of buttons sent in m_buttonStatus to 32 => We aren't able to accommodate this request. It would require us to expose axes, of which there are many and they would be different on the many wheels we support, so this would be too large a task to look at now. 6 5 Quote Link to post Share on other sites

acidrain42 3 Posted July 9 Share Posted July 9 (edited) Thanks for publishing the spec, I was eagerly waiting for it! As a side note, would you be open to use a more developer friendly format than docx? A plain text file would probably be better imo as I could open it in an IDE. Even wilder idea: publish the .h files on github! Edited July 9 by acidrain42 3 Quote Link to post Share on other sites
XanderSJX 94 Posted July 9 Share Posted July 9 (edited) Thanks a lot, in the end my urge to do some python last few weeks will be responsible for me getting this game. 😁 I like some of the updates listed above, helps a lot. Especially AI value and session identifier. EDIT: @Hoo in participant packet, myTeam field. That is 1 only for me and my teammate. Do I understand it correct?

gparent 14 Posted July 9 Share Posted July 9 (edited) I will do my best to continue updating the spec and publish it in a format that's easy to work with for the community, as opposed to a proprietary document. I'm a little late but I haven't given up. https://gitlab.com/gparent/f1-2020-telemetry/ Example for 2020: https://f1-2020-telemetry.readthedocs.io/en/latest/telemetry-specification.html Edited July 9 by gparent 2 4 Quote Link to post Share on other sites
codylane482 2 Posted July 9 Share Posted July 9 I really appreciate your help gparent. You made some great work with f1-2020-telemetry and cleaned up a lot. I appreciate your contributions. I also have something I've been working on for a while but my focus was to basically take a C or C++ structures and unions and turn it into python code + tests for the code. So far it works with pcars2, f12019, f12020. I plan to add support for f12021 and once that is done. I plan to open source it as soon as it has support for f12021 which I should be able to do before the weekend is over. 1 Quote Link to post Share on other sites
codylane482 2 Posted July 9 Share Posted July 9 As promised here is the output of copying and pasting the udp-specification into my parsing library. This is just the python code for the udp specification packet structs but I hope that it helps others get started quickly on writing the UDP handler and what to do with the packets once they are received.

cjorgens79 14 Posted July 10 Share Posted July 10 (edited) On 7/8/2021 at 9:38 PM, BarryBL said: Fixed in Future Patch Release (date tbc) Add extra byte to indicate if this is the final packet in a batch => we didn’t want to change the packet structure at this stage, so instead have made a change so that the final session history packets are sent AFTER the final classification packet, so if you watch for the session ended packet. This change is expected in a future patch of the game. One thing I would like to query though (related to general output of SessionHistory, not specific to end of session) is what happens with those SessionHistory packets when the telemetry frequency is not 20Hz. To explain further, when using 20Hz telemetry the SessionHistory packet gets included as part of the batches of other packets that fire at the regular telemetry interval, they all share a common m_frameIdentifier. The docs for SessionHistory says "This packet works slightly differently to other packets. To reduce CPU and bandwidth, each packet relates to a specific vehicle and is sent every 1/20 s, and the vehicle being sent is cycled through", which indicates it runs at 20Hz, so what happens if the telemetry rate is set to 30Hz, do those SessionHistory packets just get sent separately at 20Hz (with their own m_frameIdentifier), or will they still get included intermittantly in the regular telemetry batches? (as obviously the update intervals no longer overlap perfectly between telemetry batches and session history 20hz). Still Open Session History info from previous session is sent following a restart. Just to clarify this isn't just related to restarts, it happens when the game transitions between session types in normal use as well, ie prac to qual, or qual to race. Just a couple of comments in red regaring the above points. Cheers Edited July 10 by cjorgens79 Quote Link to post Share on other sites
Rawrocopter 0 Posted July 11 Share Posted July 11 Can someone give me an updated list of which driver numbers are user-selectable for a custom driver?

cgfdoo 36 Posted July 12 Share Posted July 12 Just started using the deluxe edition on PC and I’m experiencing weird, mid-lap session type changes in TT sessions (haven’t tried other session types yet) and my teleportation detection code triggers randomly with “teleportation distances” being all over the shop, sometimes a few meters to hundreds of meters. the teleportation thing might be on me but is anyone else seeing that kind of behaviour? While I know that there is no guarantee for UDP to arrive/arrive in order, this never happened to me in F1 2020, only in the 2021 Version. I’ll debug my own stuff some more tomorrow but wanted to see if others see this issue as well. Quote Link to post Share on other sites

I’ll debug my own stuff some more tomorrow but wanted to see if others see this issue as well. Well, my tool worked with the beta in all modes with no issues. But there was no TT in beta, so I could not test that. I also just did quick testing with the deluxe version. In race (solo race, did not enter an online race yet), my tool works as expected and all data seems to work ok. BUT, in TT there is something odd going on, which breaks my tool. I haven't dived into the data feed details, but hopefully will have tomorrow some time to look, what is going on there. Cheers. Quote Link to post Share on other sites
bruschetta85 0 Posted July 13 Share Posted July 13 Thanks staff, really happy with the udp updates you made. I wanted your advice for calculating the gaps between cars in real time. The only way I have found to perform the calculation is to identify the position of the player and check the distance in meters traveled by the car player, I do the same thing with the car that precedes and follows, obtained the distances thanks to the variable m_speed , I calculate time using the inverse formula speed = space / time subtracting the result from my time I get the front gap, adding I get the rear one. Small problem if the two cars are in different sectors, one slower and the other faster, the gap becomes fluctuating. has anyone found a better solution than mine?

Turns out I was just being a massive doofus, a little bit of moving some of my logic around and handling "late" packets better, solved the issue for me. Best guess is that it was a pairing of a bug in my code with packets being out of order more often compared to F1 2020, at least on my hardware. Carry on, nothing else to see here.

sim913 7 Posted July 13 Share Posted July 13 I'm investigating two issues that occur inconsistently for me. It could just be an implementation issue on our side, but I wonder if anyone else is seeing the same things: In some sessions, I see the Lap Data packet being sent after crossing the finish line without incrementing the currentLapNum. As an example, in a race, after crossing the finish line on the last lap, I get a few more Lap Data packet with currentLapNum = last lap number. I don't think this occurred in F1 2020. This is an issue because we need to map telemetry data to lap distance & time data. With the Lap Data packet not consistently incrementing the currentLapNum, we'll have to implement some custom logic to handle these instances. In some cases, it seems like the Session History packet is not sent during the last lap. This means that we receive the Session History packet data for the last lap, and the previous lap (second last), only with the final classification screen. This is not a huge issue to us, because we do get the data eventually, but it would be nice for it to be consistent. We'll keep investigating this on our side, but I'd appreciate any feedback if anyone else sees the same behavior. 1 Quote Link to post Share on other sites

As the id of TT is now 13, instead of 12 (as in F1 2020), my tool got stuck in "Event changed" loop, and it only happened with TT, as for other events the ids are same as with F1 2020. Cheers.

sim913 7 Posted July 14 Share Posted July 14 One of our users just completed a race session with Team ID = 41, which I can't find in the appendix. Is it missing from the table? Does anyone know what team ID 41 maps to? Quote Link to post Share on other sites

I believe in previous versions of the protocol Team 41 indicated it was a "Multiplayer" team, so I assume it is still the same even though its not documented in the latest spec by looks of it. 1 Quote Link to post Share on other sites
Lopensky 3 Posted July 14 Share Posted July 14 Am i the only one who has a fixed zero into the sessionTime value in the header? Quote Link to post Share on other sites

I was looking at that field in the data yesterday and it was working fine for me on windows version. It is zero for a bit before session starts and after session ends, but during it was ticking over just fine. I was looking at data from single player sessions at the time though. 1 Quote Link to post Share on other sites
Lopensky 3 Posted July 15 Share Posted July 15 Ok thanks! So I'm probably missing something within the released game packets' format, I'll check it out and let you know what the problem was, just for completeness. ☺️ Quote Link to post Share on other sites
