In hindsight was it pretty easy, as it is pretty clear in the code. The reason it got stuck on the app_uart_get was because it was waiting for a command but never got any (because I ran the code from SEGGER and not from the terminal).

The code does later take in a bit map where specify TX or RX and which channel to use.

Hi,

The radio_test example is a low-level radio example that doesn't follow any specific wireless protocol. I suggest that you check the info slide that I linked in my previous reply and test the example. I don't see any reasons for why the example wouldn't work in your use case.

My goal is to create interference towards my other node. The purpose with DTM is that it doesn't follow any IEEE 802.15.4 rules. I'm unsure how the radio_test example work, but if it follows the 802.15.4 will it not work as an interference debugger.

Hi,

Maybe the radio_test example is a better fit for you? The DTM example implements the DTM functions as specified in the BLE spec. The radio test example is much easier to configure and customize. See the radio_cmd.c on how the radio is configured during run time.
