RE: OpenThread set txpower, defaults

Hi Marjeris

Thanks for the hint.

I implement it in the callback registered for otThreadStateChanged where I have the context pointer and
can retrieve the instance.

static void update_txpower(struct openthread_context *context)
{
  int8_t power;
  if (otPlatRadioGetTransmitPower(context->instance,&power)==OT_ERROR_NONE)
  {
      if (power!=3) {
          power=3;
          if (otPlatRadioSetTransmitPower(context->instance,power)!=OT_ERROR_NONE)
              LOG_ERR("Radio SetTransmitPower failed");
      }
  }
  else {
    LOG_ERR("Radio GetTransmitPower failed");
  }
}

Hi,

For thread you should call function otPlatRadioSetTransmitPower() in the code if you want to set the output power.

The CONFIG_BT_CTRL_TX_PWR_PLUS_3 is only for Bluetooth and applies for the Zephyr BLE controller. This sample application demonstrate how to set dynamic TX power for BT and how to go about this.

Best regards,

Marjeris
