Understood. I don't think I can do much better at the moment, so for now I'm going to try working around it by sending only shorter strings instead and then stitching them together on the receiving end. Perhaps later the problem will manifest in a way that's easier to reduce to something that can be...

I haven't looked into what micropython's pin naming convention is, so I'm curious what you find out. I can say for sure though that it can vary from one platform to another (e.g. mbed's pin naming convention is different than what the Segger Embedded IDE does).

If you read the github post under ports/nrf carefully, you'll notice that it says that if you tack on an "sd" at the end of the make incantation, then the make will include bluetooth, provided that you also set the configuration file flags correctly. So, I'd recommend a careful reading of that, plus...

Good question. I'm guessing the answer is yes, because the default for the hardware is no flow control (see 6.33.10.13 CONFIG in the Nordic nRF52840 datasheet). So, if you defeat whatever micropython code enables it, it should default to no flow control on the uart.

Since you are able to do the build, there's nothing extra that I'm aware of.

Since you are able to do the build, just proceed as you would normally.

I haven't tried the particular modules you linked to, but, generally speaking, you'll most likely need a programmer to program them using pins SWDIO and SWDCLK. There are various programmers available, including really cheap $2 ones, but not all of them are easy to setup for use. Probably the easies...

So, for instance, after my OTA update re-writes main.py, I'll want to do a reboot so that the updated code becomes effective. Is there a generic command for forcing a reboot, or is it something hardware specific that I need to figure out on my own?

OK, I ran an experiment, and it couldn't be easier: it appears main.py can re-write itself without issue. The changes take effect only after a re-boot.
