WiFi disconnects every 110 seconds

Postby jimparis » Sat Jun 30, 2018 7:42 pm

I'm having a problem where my ESP32 disconnects from the WiFi access point after 110 seconds. It always reconnects just fine a few seconds later. The typical sequence is: Scan for APs, connect, immediately send a SNTP and HTTP request, get responses within a few seconds, then wait. After 110 seconds it disconnects with WIFI_REASON_NOT_ASSOCED.

The router is a Tenda AC1900.

This is my esp32 output:

Any thoughts? Does anything look unusual in that capture? I know very little about 802.11 but that burst of "Null function" with repeated SNs seems suspicious.

Re: WiFi disconnects every 110 seconds

Postby jimparis » Tue Jul 03, 2018 3:17 pm

Sending continuous ping requests (every 1s) prevents the station from being disconnected, but I would prefer not to have to do this.

Explicitly calling esp_wifi_set_ps(WIFI_PS_NONE), rather than leaving at the default WIFI_PS_MIN_MODEM, does not help.

Any suggestions?
