Calling wifi.radio.connect more than once causes wifi to disconnect #3735
Description
Attached is a very slimmed down example where you cannot reuse IO_HTTP. This might be a WIFI or a Request issue so I'm opening here.
Originally, I was sending data from a sensor, but you can reproduce this just using the time server on AIO.
sleep_bug.txt
The gist of the issues is:
- You can not call AIO more than 2 times
- You get different behavior if you setup your pool, request, AIO inside or outside the loop. Not sure which is supposed to be reliable.
I can reproduce this on the MetroS2 and on the Kaluga. Both running a build from 2020-11-20 of Main.
This is the setup block
## SETUP BLOCK ##
print("Setup Requests & IO_HTTP")
POOL = socketpool.SocketPool(wifi.radio)
REQUESTS = adafruit_requests.Session(POOL, ssl.create_default_context())
# Initialize an Adafruit IO HTTP API object
AIO = IO_HTTP(config.ADAFRUIT_IO_USERNAME, config.ADAFRUIT_IO_KEY, REQUESTS)
## SETUP BLOCK ##POOL, REQUESTS AND AIO outside the While works 1 time.
