This is a file system plus console plus MQTT plus take-your-pick multiplexer for MicroPython.
On the embedded device, a small single-client server runs in the background. It receives file system commands, REPL input, OTA updates, MQTT messages, and/or any other commands you might want to hook up. It sends MQTT messages, REPL output, and any replies your commands generate.
The other side (Linux, for now) starts a multiplexer which connects to that mini-server and exposes a messaging socket and a bidirectional channel for raw REPL data. It also connects to MQTT.
A FUSE driver links the messaging socket to a convenient place in the file system; it’s also possible to send file system commands directly.
A terminal program (based on pyserial-miniterm) is included.
TODO
OTA updates.
File system commands from the command line / an async Python program.
The msgpack implementation needs improvement; it is crazy inefficient. Sending a console line should eat 50 bytes (one three-element dict to be transmitted) or zero bytes (if we hand-roll the message), not 1700.
There is not yet any attempt at reconnecting. (Should there be?)
There are occasional MicroPython crashes:
assertion "ATB_GET_KIND(block) == AT_HEAD" failed: file "…/micropython/py/gc.c", line 591, function: gc_free
This definitely looks like a MicroPython bug. The problem might be related to bytearray slicing.
