Re: panic when shutting down mqtt client after publishing
You should do something like
I had similar problems when calling these functions twice. The second time crashed the app.

Re: Help with deactivating wifi please
Just disable the SoftAP by calling esp_wifi_set_mode(WIFI_MODE_STA). Calling esp_netif_create_default_wifi_ap is only necessary at the start of the app (one time and then no more). If you need to reactivate the SoftAP, just call esp_wifi_set_mode(WIFI_MODE_APSTA) and if you need to reconfigure it, c...

Station <-> SoftAP brigde (not eth)
Has anyone succeeded in creating a bridge between Station and SoftAP? So that devices connected to the SoftAP are transparently integrated into the same subnet as the Station is. Phone <-> Router <-> ESP_A <-> ESP_B Station of ESP_A might get an IP 192.168.1.2 from the router and is accessible from ...

Re: SPI mode promotion?
Looking at file "sdkconfig", CONFIG_ESPTOOLPY_FLASHMODE is either "dout" or "dio". The other two modes are not being used despite the drop-down menu in menuconfig lists them. Is that a bug or a limitation of some kind (and I overlooked it in the manual somewhere)?

Re: SPI mode promotion?
Today I looked at the header of my compiled .bin files. In menuconfig I chose "qio" mode, however spi_mode (third byte) is 2, which is "dio". Then I tried to compile the other modes using menuconfig, one after the other. In mode "dout" the value changes to 3, which is correct. All other modes result...

Re: Restarting WiFi causing increased temperature
Do you use power management? Dynamic frequency, light sleep, etc.?
The SoftAP is off?
Or maybe it is a problem with modem sleep: esp_wifi_set_ps and esp_wifi_get_ps are some keywords.

Re: How do I determine whether WIFI SSID and others config has been configured
I use if (config.sta.ssid[0]) [...] to check if the string is empty. I don't know if there is a better or official way. On the ESP8266 there was wifi_station_get_ap_info() which returned the number of stored credentials. BTW, compared to the ESP8266 there are more APIs missing, for example wifi_stat...

120 second timeout in WPS
The 120 seconds which WPS waits for an answer, is this a requirement for a standard of some kind? Or would it be possible to make it customizable in the future? In IDF 4.4.1 there is this misleading definition: /** * @brief WPS starts to work. * * @attention WPS can only be used when ESP32 station i...
