Description

I'm trying to disable wifi power savings, which seems to improve reliability of ESP32 connections on some wifi networks. According to the documentation, as far as I can tell, this should be available. And I think by setting it to less than zero wifi power saving should be disabled. In any case, the api seems to be missing on this platform. It was apparently added in #9476.

First circuitpython bug report, could be I am holding it wrong. Thanks.

I looked at this, and found that listen_interval had not been added to the Radio class dictionary. When I added this:

+    { MP_ROM_QSTR(MP_QSTR_listen_interval),    MP_ROM_PTR(&wifi_radio_listen_interval_obj) },

it showed up.

@EternityForest (author of #9476) not sure how we all missed that, but no one else had tried to use it.

I wonder if we should see if the RP2 WiFi impl has some power-saving implementation that is similar, and maybe come up with a more general API that would be applicable to both.
