Thanks. I am going to try the ratio tx and rx examples now.

Thanks for the replies. I am moving towards the idea of initiating the tests wirelessly ... but it seems like using RTT is definitely a possibility as pointed out by @twihtronics

Hi,

If you want to avoid RTT altogether you can also look at how to initiate the tests wirelessly. If you e.g. look at the radio receiver and radio transmitter examples, you could probably quite easily make the DUT power up into RX, wait for a packet, and based on what button of whatnot is transmitted from a TX (e.g. DK), the DUT could switch mode into whichever mode/state is wanted.

Another alternative is to make do with any pins you have laid out. You could emulate a button by asserting pins, even if they have been connected to things in the layout will let you control the FW or at least set up one test mode after startup.

Best regards,

Andreas

if you look at segger_rtt.h you will notice there is a SEGGER_RTT_Read function. So you probably don't need a full blown CLI just use SEGGER_RTT_Read and SEGGER_RTT_Write functions and keep it simple

maybe looking at the CLI examples might be a start. Not sure though but basically you would need to modify the standard radio test firmware to now read and write commands from the RTT channel instead of uart. You probably can just use CLI as a bases and slim it down. Also look at receiving data from RTT channel. That would be much simpler than implementing a full CLI. You just need to read and write from RTT.
