‘AT+P1’ – Lowest Power out (0.8mW)
Read Power: ‘AT+RC’ you will get ‘RP:-01dBm’
‘AT+P8’ – Highset power 100mW (reading you will get ‘OK+RP:+20dBm’)
‘AT+B19200’ – Set Baud rate to 19200
‘AT+RB’ – read out Baud rate, You will get ‘OK+B19200’
‘AT+V’ – read SW Version on Mdule, My Module gives back ‘HC-12_V2.3’
