nRF51822, modify radio output power

[Sébastien Despont]

Hi,

I am working with nRF51822 and softdevice.

I am trying to modify the radio output power without success. How can I do that?

I have found a softdevice function for nRF51422 sd_ant_channel_radio_tx_power_set, but this function or similar doesn't exist for nRF51822.

Do I need to modifiy the register directly with command like this :

    NRF_RADIO->TXPOWER = (RADIO_TXPOWER_TXPOWER_Pos4dBm << RADIO_TXPOWER_TXPOWER_Pos);

If yes, when can I play this command? All my tries are not working.

Please, help.

Are you using the BLE stack, or are you using the radio in a proprietary mode?

Hi,

Thanks for your comment. I am using softdevice 110 6.0 and SDK 5.2. The BLE stack is managed by the softdevice. I don't know exactly what is the "radio priorietary mode", but I would like increase the radio output power +4dbm for Nordic "ble_app_hts" project for example.

Hi

You can see documentation for the function here to set TX power when using the softdevice.

For discussion on setting TX power, see this thread
