I read somewhere that nrf52 has default tx power 0 dBm (I use S132 softdevice). I would like to set it to +4 dBm. How to do it? I know sd_ble_gap_tx_power_set function exists but it is complicated for me (it has 3 parameters). I just want my device to always use +4 dBm. How to do it? Is there a function that sets tx power and has only one parameter (tx power)?
