Additional introduction:

HM-10 is Bluetooth V4.0 BLE version. Use TI Chip. HM Bluetooth module use CSR BlueCore or TI CC2541, Master and slave roles 

in one, transmission version and remote control version and PIO state acquisition functions in one, Support the AT command modify 

module parameters, Convenient and flexible. Transmission version can be used to transmit data between two Bluetooth devices.Remote 

Control version can be used to Control PIO ports output high or low level without any other MCU.
