HI everyone,

I am using TSR9518B chip to build Border Router with Raspberry Pi 3 But I followed the instructions in the file

Telink Matter Developer s Guide to step 7 of 5.3 Usage, and it reported an error that the form could not be sent ("FORM operation is failed").

I tried reading uart bulletins but they don t send or receive anything.

I changed the uart config according to the instructions in the file but still the error. How to fix it?

Hi,
Maybe Raspberry PI failed to communicate with the Tlsr9518 board serial port,

1 check the  /etc/default/otbr-agent file config,

2 can you find the serial port in /dev/ directory?

3 Does tlsr9518 board has flashed correct RCP image?

Thanks for your help.

I fixed it. Because i have not run the necessary services and have not installed wpas for rasp.
