(WIFI) STA get disconnect after esp_restart() is used.

[Jayshree Shivalkar]

Hi,

Currently we are working on stable esp-idf 4.2 version, "Merge branch 'bugfix/ppp_deinit_failure_v4.2' into 'release/v4.2'" for our project.

As of now we are facing some issue of Wifi disconnect issue after esp_restart(); as normally it used to work fine with the lower version but facing issue after porting with our application with 4.2 release version. As of now after esp_restart(); our device get reboot but further it won't connect with Wifi. For better understanding i have attach the Debug logs after restart which are coming internally from wifi components. Would you please let us know if anything is missing or any changes need to do in menuconfig which can fix this issue.

I have just tested the following code on an ESP32 (DOIT ESP32 DEVKIT V1) void setup() { Serial.begin(115200); WiFi.disconnect(); delay(1000); //Wait for ESP.restart(); } Is is possible to have the STA connected to an Internet-connect AP, so the But as long as I use the default IP, etc., all seems fine.

Hi, thanks for your reply we have use esp_restart(); on successfully download and then installation of firmware through over the air.
Our device get reboot once firmware is install, but unfortunately device is unable to reboot and further all tasks are suspended and get get due to wifi task is suspended. Would you please let us know if anything is missing or any changes need to do in menuconfig which can fix this issue?

-When we tried to find out the Wifi disconnection issue we got reason as 8 i.e (WIFI_REASON_ASSOC_LEAVE = 8).
-Still we are facing issue if you have some solution for this then let us know.

Thanks in advance,
Jayshree Shivalkar.

-We are not disconnecting Wifi before restart. Because once device get restart it should automatically need to connect with Wifi and notify user about Firmare been updated.
-Please try to restart and check without Wifi disconnection.
