 This is to discover the MAC address of Bluetooth Low Energy device around you.
 It's not perfect because decoded data can't pass CRC, hence there will be 1~2 bit error in result.

 You don't need to change the frequency, since all Bluetooth device will broadcast on the pre-set frequency.
 You might need to adjust gain though.
 
-Theoretically, it's possible to decode some data in the ble packets, like temperature, but it doesn't make sense if there is bit error.
