python implemention of the host side of the MMDVM serial API. Obviously not complete, there's no way I can duplicate G4KLX's copious output overnight and I have no intentions of trying. I really just want M17 to start! Happy to help others get the other parts working too.

pyMMDVM

a python interface (over serial) to an MMDVM modem or hotspot

Why would you want this?

Well, for one, it's effectively a high level documentation of the MMDVM serial protocol. I'll include the docs and links to other code that I referenced to write it, too.

For two, it allows some very high level work with these modems. Low-speed serial is simply not demanding on a CPU, and the tradeoff to a high level language like Python is strongly in your favor if you're learning or building a proof of concept. You can do more, faster, and with a lot less effort, so Python makes a fantastic language for research and development while still being very useful in production.

For three - I like Python. We don't all like the same things, and we needn't.

If you don't like it, feel free to port this code and all its capabilities to some other language. Let me know how far you get, lol.

For four, I need to interface with a serial MMDVM modem in C on a different platform and wanted to be sure I fully understood how to communicate with it on a platform where the hardware wouldn't be in the way. Hence Python on Linux.

MMDVM serial protocol: Hints and tricks

• The modem must have been configured with SET_FREQ and SET_CONFIG before it will transmit.
