Change DTM TX Power in Zephyr

[ZL_Chiu]

Hi

Platform is nrf52804 , The DTM default tx power is 0 dbm in Zephyr . How to change Default TX power to +4 and +6 dbm ?

Hi,

 

DTM does not include a way to change the output power, so we have expanded this with a vendor specific API, which only our tools implement, like nRF connect for desktop, DTM application.

To change the default output power, you need to change this line:

https://github.com/nrfconnect/sdk-nrf/blob/v2.7.0/samples/bluetooth/direct_test_mode/src/dtm.c#L435

 

To for instance "8" if you want +8 dBm output.

 

Kind regards,

Håkon
