Problem connecting my ESP32 to the WiFi router

Need Help With My Project
1

Hi.

I have a problem connecting my ESP32 to the WiFi router. Inside the Setup function my program sometimes stays stopped in the line:

Blynk.begin(auth, ssid, pass);

Normally I have to reset the ESP32 board 3 or 4 times to get connected to my router’s WiFi, I would like to know if this has happened to someone else. My routes is a Linksys WRT54GL which is very close to my ESP32.

Thanks

you should enable blynk serial debug and check, maybe it will provide additional info. also, do not forget that esp32 core is still very buggy, so, can happen anything.

Thanks wanek.

Sometimes when the ESP32 does not connect to WiFi on my router, I get the following message.

Other times that does not connect to WiFi does not even get the last 3 lines of the previous message.

Thanks.

i do not have too much experience with esp32, but based on the above message it seems the issue is rather esp32 core related than blynk. make sure you have the latest arduino ide, esp32 core, blynk lib.

if the problem still persist, you should ask on the esp32 forum / github what that error message means.
