Explaining wifi debug messages #171

Closed binloan closed 6 years ago

binloan commented 7 years ago

I built the esp32 port on my HUZZAH32 and when I successfully connected to wifi I get constantly the following warning:

W (544828) wifi: noTIM!!

What exactly does this mean? Can someone explain this to me? I guess I can ignore it, but I still would like to know its origin. Thanks

This error message comes from the binary portion of the ESP IDF, which MicroPython relies. You'd probably be better off asking on the IDF forums.

My guess is that it might be something to do with this: https://en.wikipedia.org/wiki/Traffic_indication_map but since it's part of the binary firmware blobs there's no easy way to tell.

@binloan Probably your best bet is to write a small snippet of C which connects to your WiFi and see if that reproduces the problem: this will let you report it to the ESP-IDF issue tracker at https://github.com/espressif/esp-idf/issues

I'm going to close this one since there's nothing the MicroPython project can do about it ...
