Re: [nRF52] How to get rshell to work with an nRF52?

I noticed Mouser now has the nRF52840-Dongle in stock for $10. I've been waiting for a supported BLE MicroPython chip. Is rshell compatible? Are prebuilt binaries available? How does the MicroPython port compare to the CircuitPython port? AFAIK, there still is no micropython release for the dongle....

Yet, the nRF52840 comes standard with 512K of flash memory
Correction: I misquoted the spec. Actually, the nRF52840 comes with 1 megabyte of flash memory, not 512K of flash.

[nRF52] Any examples on interrupt handling for the nRF52?

I did read the generic documentation on interrupt handling (https://docs.micropython.org/en/latest/reference/isr_rules.html), but I'm having trouble imagining how that works with the nRF52. One or more demo code examples would be helpful. I've made some further improvements to my OTA code, but to ge...

Thanks! Now that we've solved that, I added your code back into the official github release: https://github.com/rabbithat/NRF52840_M ... TA_Updates

Check to see if MICROPY_PY_ARRAY_SLICE_ASSIGN is set to 1 in the mpconfigport/baord.h file
Good news: that worked. However, for the benefit of other readers, I think you probably meant the mpconfigport.h file.

:D

Not sure if this helps or not, but here's the result on a BBC micro:bit (which is an nRF51822): >>> radioBuffer = bytearray(256) >>> mv = memoryview(radioBuffer) Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'memoryview' is not defined >>> Is memoryview a par...

You can use frozen files, or you'll need to use a different filesystem.
What other file system is there that I can use?

Re: [nRF52] How do I increase the amount of flash allocated to micropython's micro file system?

Sadly, I'm now up against this limit. I'm more or less halted until it can get resolved.

Who knows how to fix it? You? Glenn Rub? Somebody else?

Re: Use micropython to do dead simple "over-the-air" code updates

OK, until that gets sorted, I reverted to the prior copyStringToRadioBuffer definition for the current files posted on GitHub. That way anyone downloading the files should have something that works. I also made a few upgrades: 1. Rather than running open loop and transmitting each packet 3 times, th...
