I want to set the transmit power kevel of BLE on QN9080 board and I used the Gap_SetTxPowerLevel (); API to set the transmit power for Advertisement channel and Connection channel.


When I am setting up the transmit power using this API, I received the gHciUnknownHciCommand_c error in gTxPowerLevelSetComplete_c event in generic callback BleApp_GenericCallback() function 


I used following API call to set the power.

Gap_SetTxPowerLevel(10,  gTxPowerAdvChannel_c);

Gap_SetTxPowerLevel(10,  gTxPowerConnChannel_c);


I also tried to power level value from 0 to 20 but there is no change the transmit power and hence no change in RSSI value in RX side.


Can you please help us to set the transmit power on QN9080 board ?
