I bought a HM-10 bluetooth module (similar to HC-05) because it is advertised to have a range of up to 100 meters. To get to 100 meter range however, I need to change the default power setting from 0 dbm to +6 dbm. The HM-10 command to reset the transmit power output is 'AT+POWE3' (inquiry is AT+POWE?).
I'm assuming I need to set this every time I power up. The spec says nothing about non-volatile memory.
Anyone have examples of this in C++?
