Setting up radio with nrf radio_test sample

[kongstrupp]

Hi!

I am currently working on this sample with an nrf52840 board and a nrf52832 board:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/peripheral/radio_test/README.html

I want to mod this sample so that I can receive any bytes on the 2401 or 2480 MHz frequency channel. The sample also contains a printing function for printing the payload that have been received, Is there a way to configure it so that it also show the preamble and other aspects of a packet?

What I cant understand is why the radio sets and "rxaddresses" in radio_test.c in radio_config row 145. Is this preventing me from receiving any bytes on of these frequency channels that I am interested in? Moreover, what does transmission_pattern do in this sample?, when trying the radio with the instructions in the documentation you need to set a pattern for the receiving radio, why?  

If anyone does have an answer to any of these questions, I would be grateful if you could share some of your knowledge.

Thanks!

Hi there,

I want to mod this sample so that I can receive any bytes on the 2401 or 2480 MHz frequency channel.

The radio needs to have a address match to receive data on RF channels, it does not support receiving any packet that is transmitted on that channel. The transmission pattern is related to the payload, and test specifications often have a certain pattern that they require the payload to be set to. You can use for example TRANSMIT_PATTERN_11110000.
