u360gts does not implement any usb driver. Yo must use a USB-TTL adapter ti conect to any serial port (usart/softserial). El mié., 31 may. 2023 10:32, whoim2 @.> escribió:

Im try connect usb-ttl to telemetry port (pa9/pa10) and sser (pb1/pa7) at bauds 115200, 57600, 38400, 19200, 9600 - no results. Led on board slow flash. (2 brightness stages, 4 sec cycle). Trying to swap tx/rx.
At sser port see '000000' from board to adapter, on any baud settings.

Can't connect without mag? he hasn't arrived yet.
