TypeError in reconnect #2

Closed juansezoh closed 4 years ago

juansezoh commented 4 years ago

Hi,

When the 'connect' response is 'None'?. Any idea?.

Traceback (most recent call last): File "main.py", line 97, in <module> File "/flash/lib/robust2.py", line 111, in reconnect File "/flash/lib/robust2.py", line 104, in reconnect File "/flash/lib/simple2.py", line 268, in connect TypeError: 'NoneType' object is not subscriptable

Thanks.

What version did you upload?

On which device did this problem occur?

What version of Micropython has the device?

Hi, thanks for your prompt response.

Version is: umqtt.robust2: New version 2.0.2 Device: Lopy4 1.20.rc13 Micropython: 1.9.4

Is it possible that executing 'resp = self._read(4)' line 267 in simple2.py requires a little delay?.

Can you also tell me how can I make the Debug in the console complete? Is client.DEBUG = True enough? Only a few errors come out.

In version 2.0.2 of the robust2 library there is a comment in line 104. So there shouldn't be an error there.

Please install the latest version of robust2.

When DEBUG=True, only the exceptions captured by this library are displayed.

So it's not really a complete debugging tool, but rather a preview of the problems.

It could be improved, but we have a limited amount of RAM on the devices.

If you need to debug the code, you can use MQTTClient class from the file: https://github.com/fizista/micropython-umqtt.robust2/blob/master/tests.py

I threw in a new version. Try it.
