Hi!
My goal is to output a constant carrier signal on the nrf21540-DK
I've loaded the radio_test on my nrf21540-DK. The location of the test is /opt/nordic/ncs/v2.2.0/nrf/samples/peripheral/radio_test
However, the maximum power allowed in only 8dBM and I do not see support for the nrf21540-DK in the configuration files.
My question is how to run the constant carrier test using the nRF21540-DK?
Thank you,
Andy
Hi,
I have not tested the latest NCS release but is should work. Thanks for commenting on the documentation, will take that to note and provide the feedback internally.
The nRF21540 should not be served more than +5dBm, so can configure the nrf52840 to do +4dBm. But in the latest resales it should be done automatically.

If you continue on having issues you can test with a older version of NCS. Version 2.0.0 should work as its the latest I tested.
You can use the FEM command to set the specifics.
