MicroPython Forum (Archive)

My projects tend to be on the infrastructure side of things resulting in microcontrollers stuck somewhere doing some thing for a long time, sometimes a decade. At the same time, a lot of these projects are experiments that I keep tweaking even once they're "deployed" and "in production". So I need a...

There is no official guide. I wrote an OTA class for my MQTT Repl, which you can find here: https://github.com/tve/micropython-mqtt/blob/master/mqrepl/mqrepl.py#L22-L84 It streams the data from MQTT (~1000 1400-byte messages) directly into the partition. The file you need is the application.bin sinc...

Sounds like a fun project, if you manage to port the flashing code I would be very interested in using it!
I wonder whether the protocol is documented, it might be easier to start from the docs...

If that's the GPS coord issue, yeah, represent your lats and longs using integers. You can use fixed point arithmetic or you can represent the whole thing in 1000000th degrees, which will use bigints, but that's perhaps still better than having everything use doubles.

I don't think you specified what type of device you're accessing but could it be that you should use I2C.readfrom and not I2C.readfrom_mem?

I haven't used mDNS, but I believe it simply responds with the hostname set on the STA interface + ".local".

> I bought a pack of 10 on AliExpress and have used them in many things. When comes the point where the best thing to do is to put those 10 into a little baggie, put a "Mistake!" note onto it, pin the whole thing to the wall in front you as a reminder, and then order a couple of esp32 boards? ;-) ;-...

This would be best posted as a github issue...

Have you double-checked the strapping pins?
Please post logs starting from the reset.
