ESP32-Wrover Random Reset

[abrinlee]

I am attaching to the Cayenne network and passing data but it appears I am missing an exception handler...

Here is the error

This issue may be an issue with the espif arduino library for the ESP32 the debug shot is for the libpp.a file in the esp32.

Yeah, that could be a bug in the ESP32 board package. If you try with an example sketch that just makes a WiFi connection to a server and doesn't use the Cayenne library do you still get the error? If so, you might try opening an issue at https://github.com/espressif/arduino-esp32/issues.

[abrinlee]

It does happen even with a standard WiFi connection. We can close this issue here.

Unfortunately I think they still are having some silicon issues that need resolved.

Okay, thanks for checking. I'll close this issue.
