[Question] How to set OTBR_RADIO_URL ?

[OlivierGre]

Until now, we were editing src/agent/otbr-agent.default.in to indicate which device to use (we used ///dev//ttyUSB0 in replacement of ///dev//ttyACM0). The content of this file is copied to /etc/default/otbr-agent.

I can see that the file now contains "OTBR_RADIO_URL". Can you please tell me how to overwrite it? Shall I set an envionment variable on the Raspberry Pi?

Thanks
