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>
