https://devzone.nordicsemi.com/f/nordic-q-a/111410/advertising-tx-power-only-in-scan-responseI need to add tx power to my BLE advertising, but I need to ensure it is in the Scan Response only not the main AD PDU. Also, I change the Tx power by code using the function sd_ble_gap_tx_power_set(), and I need the scan response to update accordinglyen-USTelligent Community 13Wed, 22 May 2024 14:24:15 GMThttps://devzone.nordicsemi.com/thread/485458?ContentTypeID=1Wed, 22 May 2024 14:24:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0956ba83-15bd-4e8f-b486-6d2ed218a601Kenneth<p>Hello,</p> <p>If you want to update the content of the advertisment or scan request packet you need use&nbsp;ble_advertising_advdata_update(), where you for instance before calling the <span>ble_advertising_advdata_update()&nbsp;</span>change the&nbsp;p_tx_power_level field in p_srdata.</p> <p>Also, if you are interested in actually changing the output power during advertising you can use the&nbsp;sd_ble_gap_tx_power_set().</p> <p>Kenneth</p><div style="clear:both;"></div>
