[DISCUSSION] F1® 25 UDP SPECIFICATION

In the new lap positions packet, the array is documented as

uint8 m_positionForVehicleIdx[50][cs_maxNumCarsInUDPData];

For those who are reading the spec for the first time , it is not obvious that cs_maxNumCarsInUDPData is 22 (my guess, if I'm wrong it just reinforces my point). Please clearly specify what this constant is.

Also, can we please get this thread pinned. It tends to be one of the more active threads every year.

I thought I had pinned it... my bad. It's pinned now on the General Discussion boards.

Also, IDK if its just me. Every packet in the spec so far has been indexed by driver ID. This new lap positions packet alone is indexed by lap number. I can work with this, but feels odd and inconsistent

EA_Groguet​ I've reported a bug in UDP telemetry. 0 is being sent as game year before race (should be 25).

UDP telemetry - Game year is reported as 0 before race start | EA Forums - 12214767

Please forward it to the team.

Not a big deal but in the documentation, there's still the typo on Hulkenberg's name :D .... "10 Nico Hülkenburg" (in the driver id appendix)

uint8 m_tyreBlisters[4]; // Tyre blisters value (percentage)

is this already used in the game F1 25?

Hi can I have some help.

It seems the playerCarTelemetryData.m_tyresInnerTemperature packet sends data at 01/02/03/04 but the documentation says the tyres are 0 rear left/ 1 rear right / 2front left / 3front right.

which wheel translates to the 01/02/03/04 packet please

Hi there, according to the spec, tyresInnerTemperature in the car telemetry packet is an array of 4 uint8's. If you parse the incoming packet as an array of 4 uint8's, the documented numbers are the indices in the array representing those tyres. So I'm not sure what you mean by 01/02/03/04 packets (assuming they are not packet ID's, since those do not correspond to the car telemetry packet).

Please share a code snippet/screenshot so I can understand better. Also, is this something you're trying to build for simhub? If so, you might want to ask around on simhub forums/discord.

Hi EA_Groguet​ , 

I would first thank you for sharing us the document and the ability to let users have the udp specifications, also caring about us. That kind of availability is very rare and i recognize that could be very demanding. 

I was wondering if there could be a value in the F125 UDP specifications which shows the Delta time that appears on the steering wheel or either on the time trial mode up in the right box. That would be VERY useful. If there is none, is there a possibility to get it anytime soon?

Thanks,

Mattia

Hi ragekumar666

GameRawData.PlayerCarTelemetryData.m_tyresInnerTemperature02 is the code snippet. I'm trying to work out which tyre the 01/02/03/04 ending relates to.
