M5StickC firmware to send 6DOF sensor(SH200Q or MPU6886) data and quaternion by Bluetooth serial port protocol(SPP).

This is demo. M5StickC calucutates and sends quaternion to PC by SPP. PC receives quaternion via serial port.

M5StickC sends raw value of 6DOF sensor.

• Acc(xyz) [G]
• Gyro(xyz) [deg/s]

M5StickC calucutates quaternion by acc/gyro and sends it.

• Quaternion(xyzw)

M5StickC sends button A/B push/release event trigger.

• Button A Push/Release event
• Button B Push/Release event

This project use PlatformIO.
