RAK 11300 and Micropython.

[mrpackethead]

Hello Pythonists,

Im wondering if anyone else is trying to use micropython on using RAKWirless's RAK11330?

Its got a RP2040 on it, so it should not be too far of a stretch to do it. ( i've got some on order, hopefully coming in the next week or so )..

I'll be looking for lora / lorawan modules

The 2.0 to 3.6v supply range means it will need an external voltage reg to run it from a lipo, but nice price. I'd be interested to see how well it works. I had a lot of grief trying to connect Pycom's lopy4s to TTN few years back, OTAA sort of worked but ABP was hopeless.

I had the opposite experience with ABP and OTAA. While ABP always worked, once set up properly for all times, OTAA had problems with timing and signal levels.

Its essetnially an RP2040 and a SX1262..

Are there exisiting modules to make that work? Any pointers.

I found this.. ( https://github.com/lemariva/uPyLoRaWAN )

FYI, still finding my feet with micropython. I'm a long time Python coder, long time electronics guy, but trying to fill in the gaps..

It was suggested on the rak forum https://forum.rakwireless.com/t/microp ... 310/6431/2 that perhaps that i could use the repo

https://github.com/lemariva/uPyLoRaWAN

and port the sx127x.py to SX1262.

heres a port of the sx1262..

Looks like most of the works been done.. i just need to join this all together.

The parts arrived in the mail yesterday

So, i've hit a bit of a setback.. and not entirely sure what to do next. I put the RAK11300 into bootloader mode. Got the RP2 drive up and copied the RP2040 Python UF2 file into it.. It Immediatlely rebooted, as expected , and COM6 appeared on my machine. ( i'm using windows 11, Pymakr and Vscode ).. The REPL just doe'stn want to respond.... ( nb, its fully funcitonal running the arduinio code )..

Do I need to build a custom version of micropython?
