Additional introduction: HM-10 is Bluetooth V4.0 BLE version. Use
TI Chip. HM Bluetooth module use CSR BlueCore or TI CC2540,
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. HM-10 Diagram
