decobayer

Python package decobayer attempts to implement remote protocol for Bayer Contour Nextlink.

Status Quo

Work in progress:

• can get into command mode python -m decobayer.modem
• can read talk to pump remotely: python -m decobayer.remote As a test, this reads SERIAL environment variable, and reads that pump's model number. (In order for this to work, the comm's need to be initialized already, use openaps or mm-send-comm.py to initialize comms.

Help needed

• PowerControl
• Sending parameters
• Identifying CRC's, length fields
• Reading long frames, identifying length fields to determine when frames are done
