OBDLink LX CAN-bus not sending some ID


I'm using an OBDLink LX on RaceChrono Pro 7.1 (Android) as raw CAN-bus reader.

The app can read some ID such as 0x201 (rpm, accelerator pedal position, car speed) but not IDs 0x81 (steering) and 0x85 (brake)

For 0x81 it seems to read the first value and then get stuck at 00 00 00 00

Is this something to be fixed to RC side or a limitation on OBDLink side?

I know those IDs are available on the port because I logged them with a PiCan2.
