Hello,

There is a register for this on the nRF53 as well.

Please see the TXPOWER register documentation.

I don't know what TX power you need. But as you can see from the description, if you want higher than 0dBm, you need to enable the VREQCTRL.

You need to control this from the network core. I don't know whether we your application is using the network core to handle radio stuff. (we do not support contiki from Nordic's side).

Just sharing the answer from Contiki's forum:

You can set the TX power using the RADIO_PARAM_TXPOWER parameter, i.e. something like:

NETSTACK_RADIO.set_value(RADIO_PARAM_TXPOWER, (radio_value_t) RADIO_TXPOWER_TXPOWER_0dBm);

You will need to include netstack.h.
