Hello,

I have a usecase where I have to use PX4 stack without libuavcan for accessing the Nuttx-CAN interface on Aerocore2 board (based on STM32 microcontroller). Currently I have modelled my CAN module based on the Nuttx CAN example. While executing the module I didn’t get any error but I can’t see the traffic on CAN bus.

Can anyone, @pavel-kirienko provide some input here?

PS: I have used `/dev/can0’ as the CAN device as per Nuttx example.

Thanks,  
Mani
