GPS crashes on invalid input about micropython-async HOT 3 CLOSED

Thanks for your prompt reply!

I already "fixed" this by adding try/except to the readline call, but your suggestion to add timeouts seems to work too so I now reverted back to unmodified uasyncio. :)

I'm using Raspberry Pi Pico, sorry for not mentioning it in the first place.

I'll close this issue. I'm sure you are right that if there's anything to fix it's in micropython's side.

Sorry, I just realized line 185 is the readline(), not decode().

So perhaps need to move readline inside of "try"?

I think this is what is happening. The UART is timing out, returning None. This is crashing uasyncio here.

You haven't said what platform you're using but one option is to increase or disable the timeouts. These are specified as UART constructor args timeout and timeout_char. Values are in ms. Some platforms accept -1 to disable timeouts. Otherwise make them longer than the interval between GPS messages.

I have raised this issue. I'm not sure if it qualifies as a uasyncio bug.
