I am working on a native Tizen  app on a Gear Fit 2. I wuould like to create an app programmed as follows: BLE in advertisement mode and send device info (e.g. magnetometer, accelerometer data). 

I’d like to know which are the possible output power levels (dBm) and how to set them. I have discovered the following function: 

bt_adapter_le_set_advertising_tx_power_level  

is it the right one? how can i set the power level?

sincerly,

Alessandro
