Problem in changing transmitter power setting

[cece]

We are looking to change tx_power setting to Neg30 dBm and for this we have accessed NRF_RADIO->TXPOWER = (RADIO_TXPOWER_TXPOWER_Neg30dBm << RADIO_TXPOWER_TXPOWER_Pos);

When we put this code in BLE project, this line of code gets hang. Please let us know how to fix this issue.

Hi Cece,

when you're running BLE (SoftDevice is enabled), you cannot access the radio peripheral directly. The SoftDevice will block direct access to the radio among other hardware. To change the tx power you should use the sd_ble_gap_tx_power_set() function instead.
