theterg / MioDecode.py

Created December 18, 2013 20:31

Found some data on a UART channel connecting the sensor board to the bluetooth/main MCU on a Mio Alpha watch. Wrote a quick script to assist in viewing the data on this bus.

	'''
	MioDecode.py

	Reads data from the internal serial bus of a Mio Alpha and prints the BPM to screen.

	Dependences:
	-pyserial

	Usage:
	python.exe MioDecode.py --port='<serial port>' --baud=<baud rate>
