Pixracer with companion computer

#1

Hi, we’ve been working on communication between raspberry pi and the pixracer, anyone has a working configuration? We’ve been hitting on all the walls on this, haven’t got them to communicate at all. Here’re the things we’ve tried:

used firmware 1.8.1/1.8.2/1.9.0/1.6.3
SYS_companion set to 921600 (for 1.8.1/1.8.2/1.6.3)

for 1.9.0:
MAV_2_config=telem2
MAV_2_mode=onboard
MAV_2_rate=921600
MAV_2_forward=true
also tried SER_TEL2_BAUD to 921600

they always fail at after executing px4.launch and no data streaming. we are running out of walls to crash into. Anyone has ideas? Thanks in advance.

We’re successfully using the PixRacer and an Up Core, however for serial on the companion side we are using an FTDI chip (this one).

We have:
MAV_1_CONFIG=TELEM 2
MAV_1_FORWARD=Disabled
MAV_1_MODE=Onboard
MAV_1_RATE=80000 B/s
SER_TEL2_BAUD=921600 8N1

Hope this helps!
