nRF21540-dk PCA10112 hex file for nRF Connect Direct Test Mode

[rikhard]

Dear nRF,

I have couple of nRF21540-dk boards (PCA10112) in my hand. I would like to use nRF Connect Direct Test Mode to activate TX and RX.

I found that the tool lacks correct hex file for PCA10112. If I activate TX, there is no practical RF power present at the test connector, measured with NRP-Z21. I assume that there is no TX / RX configuration done for the external FEM.

Could you advise where I can get the correct hex file? 

My nRF Connect is version 3.9.3.

Fast response is very much appreciated. 

Thanks.

I expect you need to manually need to compile and program the DTM project in this case for the pca10122 in specific. This can for instance be done both by NCS or nRF5 SDK projects, e.g.:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/direct_test_mode/README.html 
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/ble_sdk_app_dtm_serial.html (open pca10112 project folder)

I have however compiled the example for you, this can be programmed from the programmer app in nRF Connect app:direct_test_mode_pca10112.hex

Note that after you open the DTM app in nRF Connect app, then click No on the pop up:
