Quite a few updates. Subscription feature is now working, which is great. This has been tested with mosquitto broker as well as Adafruit IO, and it works perfectly with both. I tried to compile this project as a library (see the changes to Makefile) but when I used that .a file in another project the linking process failed. More research needed, I've never tried to do that before. I compressed some of the case statements in mqtt_send as they are so similar, it's a waste of code space to duplicate them. Disconnect and ping are identical except for one byte, and unsubscribe and subscribe differ in only a few lines. The data receive callback now prints information on what kind of packet/data was received; again, mostly useful during debugging, but the framework is there to expand it to do useful things like triggering other tasks/timers, etc. There is now a keepalive ping timer which keeps both the MQTT and thus the TCP connection alive. It currently pings every 5 seconds, though I might change that closer to the timeout maximum (50 seconds). Signed-off-by: A.M. Rowsell <amrowsell@frozenelectronics.ca>
