NRF_RADIO->POWER intermediate levels

[florentb]

We are working on a dynamic radio power change for a proprietary RF protocol, and we are missing some granularity on the NRF_RADIO->POWER levels.

Typically we would need an output of -10dBm (possible levels are -12dBm and -8dBm), is it possible with custom / undocumented registers changes ?

Just use a different antenna configuration... SCNR ;-)

Hi

There are no hidden registers to increase the granularity unfortunately, but there have been some improvements in the later devices in the nRF52 family.

If you look at the nRF52840 for instance you have 1dB steps in the 2-9dBm range, and 4dB steps below 0dBm.

Best regards

Don't you mean RADIO->TXPOWER (with a "TX")? (A search of RADIO->POWER leads here erroneously.)
