Rebooting - Arduino IOT Cloud & ESP32 board

Development Tools Cloud IoT

Hi friends!

Hi, I'm having a problem with Arduino IOT Cloud & ESP32.
My sketch runs good until I apply ArduinoCloud.update() command. A reboot always occur after about 400 ArduinoCloud.update() executions (or 30 seconds sketch running). The serial monitor shows this message:

"Guru Meditation Error: Core 1 panic'ed (Unhandled debug exception).

Rebooting...

I've done an exhaustive search on this issue and I tried many solutions but had no success. When I comment ("//") the ArduinoCloud.update() command everything works fine. I have no idea what is going on.
I'm using a ESP32 DevModule board. Any ideas please?

Thanks a lot!

Paulo

Have you tried putting the backtrace into the ESP32 Exception Decoder to get more info?

Typically a EXCVADDR: 0x0000000 means something has went out of bounds.

Hi Idahowalker. Thank you very much for the reply. I'm a beginner and dont know how to do it. Could you help me?

4

Sure I'll try to help.

Have you tried using the words "how to use esp exception decoder" typed into your favorite internet search engine will get a result set. Look through the result set and pick a result. If it helps use it, if not select another result.

I did all the procedure and the result remains like this:

decoder results
decoder results1366×858 232 KB

It seems that something was missing in the stack trace or I did something wrong....

The code posted in code tags?

7

I made a simple debug using "Serial.print" and confirmed that the crash is at "ArduinoIotCLoud.update()" command line.
Firstly, it sometimes unexpectedly exits the void LE_ChecaSENS() (where the "ArduinoIotCLoud.update()" command line is) and goes back to the void loop(). It happens this way for a few times until the system reboots exactly when trying to run ArduinoIotCLoud.update() for the last time.

Did you undestand me? Sorry for my poor English.

8

Have you asked the people who wrote the ArduinoCloud.update() why their thing crashes?

9

Yes, I did it yesterday. No return until now.

10

which library is the arduinocloudediot using?

11

oops!

This library is DEPRECATED and is no more supported

12

ArduinoIoTCloud library.
I´m using ArduinoIotCloud Web Editor wich contains all updated versions of the libraries.

13

I'd never guessed that from looking at your code. Anyways, good luck.

14

I'll need it. Thank you!

Not quite sure if anyone from the IoT team did something today, but shortly after my post the things worked fine again. Thanks to Idahowalker for the help. I'm closing,
