Board

NINA-W101, NINA-W106

Device Description

EVK-NINA-W101 from u-blox

Hardware Configuration

ESP32 I'm running the v2.0.15 (Not listed in the Issue form)

https://www.u-blox.com/en/product/evk-nina-w10

Version

v2.0.14

IDE Name

Arduino 1.8.19

Operating System

Windows 11

Flash frequency

80Mhz

PSRAM enabled

no

Upload speed

921600

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

Regards
Paolo

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