Hello, I have ESP32 device and I’m trying to connect it to my Blynk. Yesterday it was working well. I reset my Blynk projects and devices but now when I try to connect it again, using quickstart with Arduino IDE, up-to-date blynk libraries, it keeps resetting itself, with this error message in log:
Connecting to blynk.cloud:80
Ready (ping: 327ms).
rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
and it reconnects itself again. In my blynk devices page it goes offline and online. How can I solve this?. I’m not pressing the reset buttons or pins and my board works well.
Have you made any changes to the watchdog sketch?
Exactly which version of the Blynk library are you using, and which version of the ESP32 core?
Have you tried all the normal stuff like rebooting your router, using a different USB power cable etc?
Pete.
Hello, I’m not sure I’ve made changes to the watchdog sketch.

I’m just editing my ssid and password to connect the WiFi. There isn’t a problem with it.
Blynk Library Version is 1.2.0
My board is ESP32-WROOM32 and Node32S is selected at Arduino IDE.
There wasn’t any problem yesterday but now it just resets itself.
Sorry, I was writing one thing and thinking another, which didn’t come out correctly.
I meant to ask if you’ve made any changes to the Quickstart sketch.
The Watchdog reference was because youre error relates to the Watchdog Timer (WDT) and I was wondering if you’ve added some blocking delays to your code that could cause this - but you haven’t.
You haven’t answered this question…
Go to Tools > Board > Boards Manager and search for ESP32 and tell us which version is installed.
And, you didn’t answer this question either…
Pete.
My ESP core is 2.0.7 .
Yes, I’ve tried all these steps. I also tried connecting with different ISP, but it doesn’t help either.
