@Marcidy --- just as you said: Walking through each step manually reveals that the code is hanging waiting for end_packet loop to finish... Before I troubleshoot further would you kindly just cast an eye over my schematic in my first post? This is the LoRa module I have used: https://www.lcsc.com/pr...

@Marcidy --- I am learning so much! I will walk through println step by step ad then, if need be, crack an oscilloscope I inherited. Many many thanks.

Ahhh no... I hope I am one step closer to success... This now executes without any problem (I commented out the entire section about version warning): lora = SX127x(device_spi, pins=device_config, parameters=lora_parameters) However processing hangs following this: payload = "Testing" lora.println(p...

Ahh Marcidy --- you are amazing! Thanks for your care.

I will test this and revert asap

Hi there I have no doubt that someone here can tell me why I cannot initiate communication with my sx1276: My setup: > ESP32-WROVER-B > Micropython: esp32spiram-20210902-v1.17.bin > Module: https://github.com/lemariva/uPyLoRaWAN - config.py has been modified according to my circuit layout - sx1276.p...

Hi there All (and PeterH) Please assist me with an idiot's guide to implementing MQTT using your uasyncio compatible library:(https://github.com/peterhinch/micropython-mqtt) All I need is an implementation that satisfies the following: > Callable function that publishes a string to a topic > The fun...

Hi there I have an ESP32 that is using almost all available memory --- so much so that I cannot import umqttsimple without memory allocation errors (I do acknowledge that this is likely due to extreme inefficient use of memory by a NOOB).... What I would like: > Help with the implementation of the s...

Recently we completed a prototype device which employs an ESP32-WROOM module --- this worked admirably albeit that the device is short on RAM and can thus only buffer +- 500 seconds worth of sensor data with which to make decisions. Five times this number is desirable. The WROVER module with SPI RAM...

I am indeed using the older version of uasyncio
> Upgrade pending

Following numerous reviews of the linked tutorial I now finally get it!
> I now have a main loop which starts tasks, each of which await coros as needed

As always... many many thanks for the gentle assistance.

Hi there everyone It is very likely that owing to my poor implementation of the uasyncio library, on an ESP32 WROOM32, that after a few minutes of running memory intensive tasks, bugs begin revealing themselves. All functions test well initially, but after a while seemingly random error is raised in...
