Hi - are there any updated recommendations for pure Micropython Lora libraries - are any of the ones described above "stable" (loboris/MZachmann/Wei1234c)? I tried a Lopy a year or two ago and had a few issues with timings in the Lora firmware and hardware (deep sleep) (although I think Pycom have r...

@pfalcon - thanks for your advice. Yes - I agree - compatibility with (a subset of) Python 3 is a crucial goal. That's kind of how I ended up down the rabbit-hole of this thread - I wanted to do what I thought would be a simple asyncio.gather() but realised that this functionality wasn't available i...

I've been doing a bit of reading around futures to learn a bit more and found a couple of interesting references: Firstly, Javascript has the Promises/A+ specification - https://promisesaplus.com - which has been widely adopted and is largely seen as a step-up from the previous "callback hell". I qu...

Ah - many thanks pythoncoder - that would explain it. I wasn't aware of that subtlety of python closures, I'm more used to Javascript.

I don't know why it worked at all without the nonlocal keyword - I was running on a linux 1.9.4 build.

I've been trying to simplify my gather() and have come up with a version using just coros that doesn't need the PoorFuture wrapper class. import uasyncio as asyncio async def slow_task(seconds, answer): '''Demo function to build coros that simulate slow-running tasks''' for i in range(seconds): prin...

Thanks - yes, the editor didn't seem to let me insert code blocks properly for some reason - maybe because I am new? It seems to be working now however. You are nearly there with your indentation, but I think you have some extra indention after this for loop - it should be: # start all the futures a...

Thanks - glad to hear I'm not totally off-course :) No - I don't have any ambitions beyond my simple "gather" use case for collecting results concurrently from a number of sensors - I just wanted a simple way of doing this. I'm not familiar enough with the asyncio library or futures in general to pr...

Hi, I've been playing with micropython and have a situation where I want to collect results concurrently from a number of slow (ie. a few seconds) sensors. I thought this could be a job for uasyncio and futures, but I have seen that uasyncio focuses on coroutines in preference to futures for perform...
