Description

I've encountered a problem using the library when the WiFi connection is lost due to a fading of the WiFi signal between the ESP32 module and the router. If the connection is lost, the library is no longer able to restore it again. The conditions for reproducing the problem are as follows:

Hw: EVK-NINA-W101/106 based on ESP32 https://www.u-blox.com/en/product/evk-nina-w10 Board lib package: ESP32 2.0.15 installed Sketch example: See attached,

How to reproduce the problem: The app Mailbox_Change_Notification connects to internet via a router. Move slowly the EVN-NINA-W102 (ESP32) board far from the router wifi range, until the ESP32 will lost the Wifi connection (do not switch off the router and then switch on it, to simulate the Wifi drop, otherwise the problem doesn’t occurs). Wait some second (1 minutes, see Serial.Dump, wait for that time or more, shorter time couldn't trigger the problem) with ESP32 position out of Wifi range of the router, then slowly enter the ESP 32 EVK in the range of the Wifi router. The result is that the sketch is not able to reconnect to the WiFi

The Module is moved closed to the Access point, but it doesn't reconnect. Is the AutoReconnect procedure set by default ?

chipguyhere commented 5 months ago

Is there more than one access point providing this same SSID?
