A Particle port of DFRobot's library for GoBLE https://www.dfrobot.com/wiki/index.php/Bluetooth_APP_Control
This enables the uses of genertic BLE modules like HM-10 with Particle for added RC control.
Using AT commands, set the HM-10 as follows (all other settings at default values):
AT+BAUD4
AT+UUID0xDFB0
AT+CHAR0xDFB1
Then connect hm-10's TX to Particle Serial1_RX, connect power. Good to go.
