Crash? #1

Closed brahmafear closed 8 years ago

brahmafear commented 8 years ago

Hi Scott,

Awesome code. I'm trying to replicate some of your work but am seeing my unit generate exceptions and stack overflows to serial console. I can successfully upload simple blink sketches as well as more complicated MQTT sketches, but every time I attempt using the code here, I get a dump.

I'm familiar with Arduino and ESP8266 but new to some of the JSON and EEPROM libraries you are using.

Any thoughts on things I can check next? Thanks in advance.

Can you copy/paste the serial console crash output here and relevant lines of your program. My guess would be its getting all of the libraries squared away.

Sorry, just getting back to this now. Here's is a dump of the crash I'm seeing after uploading the code. Seems to be some sort of exception (29?) generated during the connect phase. Any ideas?

Think I have a clue on this -- if the saved JSON file does not have the same IDs as what the sketch tries to extract, the module resets. Ie, if I run the program, save a JSON file, alter the program and add new JSON fields, upload to module, run -- module will crash. Workaround is to format spiffs or change the JSON file name whenever changing the JSON format.
