Regarding bl602 demo_at : https://pine64.github.io/bl602-docs/Examples/demo_at/AT.html The documentation is very complete. I compiled and flash the bin. But I can't find any information indicating which port / baud is used in the application.
I'm not 100% sure, but I suppose you have this line in your code: bl_uart_init(0, 16, 7, 255, 255, 2 * 1000 * 1000);
.
The second parameter is the TX pin and the third is the RX pin, the last parameter is the baud rate, sets at 2 000 000 in this example.
If you don't have this line in your code I don't know how its configured. ^^
