Also, just discovered:
Is 'uasyncio.gather' missing from the latest version of the MicroPython repo? It is not showing up when I import it...

By the way, apologies to the forum, but... the inconsistent REPL-interactive behaviour I was encountering per my last post seems to have been alleviated by erasing the flash memory and reflashing, so something in the firmware probably got written incorrectly... At any rate, if anyone else encounters...

Hi again, I'm also encountering another puzzling error, which may (?) be related to the type of error encountered in (2) of my post above. Also, to note, regarding my software upgrade: I did _not_ install the official v1.19 release, but instead downloaded a copy of the github MicroPython 'main trunk...

I am extremely impressed and gratified by the development team efforts! MicroPython is an amazing piece of work. Yesterday I upgraded my firmware development software (MicroPython 1.15, ESP-IDF 4.1) to MicroPython 1.19, ESP-IDF 4.4.1, using a clean installation. I'm very happy to see increasing new ...

Thank you for this discussion! I, too, was having problems with descriptors being able to neither be read nor written. As of today, the differing value of descriptor RW flags has _not_ been added to the MicroPython documentation online.

Addendum to my addendum:
- Does anyone know why, on occasion, _IRQ_GATTC_DESCRIPTOR_DONE isn't called after all descriptors have been discovered by the Central? Sometimes this happens with my test-case Central implementation (about 20% of the time).

Adddendum: Obviously this was a classic 'ID-10-T' error! In the mix-up during GATT reorganisation (a massive one), somehow the characteristic permissions were changed... '_FLAG_WRITE' wasn't checked for this characteristic (the one the Central was atttempting to write to). So, here's the answer, in ...

Hi, I'm pretty new to BLE, and MicroPython's implementation, so I've been playing around and augmenting/modifying the ble_temperature and ble_temperature_central demo scripts. Everything has been working just great in that writing to characteristics by the Central device (an ESP32) has called the ap...

I have encountered this behavior with a custom-built ESP32 board (using the WROVER module flavor). Specifically, activating the WiFi radio when the unit is only powered via serial port (analogue of USB--my board doesn't use the latter) sometimes caused a reboot due to brownout conditions and sometim...

Hi All, Second post ever here. I wanted to make sure that my first post ever wasn't 'hidden at the bottom' of an existing thread -- the one entitled "ESP32 and LVGL - Guru Meditation Error after reboot if network initialized" -- especially since the issue I need advice solving only has to do with Gu...
