Set TX power on an NRF52833

[SET]

Hi,

I try to set the TX power of the NRF52833 to the maximum possible power level, but somehow nothing seems to affect it.

I first tried to change it in the sdk_config.h from 0dBm to +4dBm, but it seems not to affect it. Then I discovered, that the default

signal strength from radio_config.h is RADIO_POWER_NRF_0DBM, so I replaced it everywhere with RADIO_POWER_NRF_POS8DBM,

but also this did not affect the power level when measured with a mobile phone. 

I have two questions now:

• How can I properly adjust the power level to constant maximum power?
• How it comes the NRF52833 has +8dBm, but this seems not adjustable from the sdk_config.h?

Kind Regards,

Sebastian

Hi Sebastian

You can check out the verified answer in this case, where it's explained how to set the TX power after a connection. When a connection is created, the advertiser (peripheral) will inherit the TX power used when advertising. so if you always want to use 8dBm for example, you only have to set this when advertising, so yes, you're correct!

Best regards,

Simon
