Re: Power management fail after WiFi join

It seems that one of the listen_interval field of a wifi_sta_config_t structure in my code was not initialized. This field is used when in WIFI_PS_MAX_MODEM mode.

Re: Power management fail after WiFi join

For a moment I was happy with the setting WIFI_PS_MIN_MODEM however the mode WIFI_PS_MAX_MODEM seems to be mandatory for my application. So I tried to change the setting just before joining an access point and the device managed to join it without crashing but it messes a bit with my application. I'...

Re: Power management fail after WiFi join

I managed to narrow down this issue to the WiFi power save settings. First, I wasn't setting the listen_interval in my WiFi configuration (wifi_config_t) so I added it and set it to zero. It wasn't working either so I tried the other power save mode (WIFI_PS_MIN_MODEM instead of WIFI_PS_MAX_MODEM) a...

Re: mDNS time to live

Indeed, the protocol must be prefixed with an underscore. I ended up using Bonjour Browser on Windows to see if my service was correctly registered and it works far better than Service Browser on Android. There should be no problem now.

mDNS time to live

Hello, I am using the mDNS APIs however I don't see any option to set the TTL of my mDNS service. The service is visible on an Android smartphone with the application "Service Browser" but only for a brief period of time (I would say one second). However I need my service to be always visible and I ...

Re: Sleep modes and Wi-Fi

Thanks. I also found in the forums a really interesting document about low power solutions : https://www.espressif.com/sites/default ... s_en_0.pdf

But it's only for the ESP8266, is there any other one for the ESP32 ? I couldn't find it.
