Hi, it would help if you could please share the code you wrote. To debug it yourself please put
mbed_trace_init();
somewhere in your main function and put this in your mbed_app.json:
"mbed-trace.enable": true,
"mbed-trace.max-level": "TRACE_LEVEL_DEBUG",
"cordio.trace-hci-packets": false,
"cordio.trace-cordio-wsf-traces": true,
"ble.trace-human-readable-enums": true
You can only have one outstaning call to le_test running so call rf_test_start_le_transmitter_test and then when you’re done rf_test_end. After that you need to call reset on ble.
