Guru Meditation Error: Core 1 panic'ed (StoreProhibited)

[kbickham]

Working on my senior design project. This is only part of my code, I even went back and broke down some of the float/double conversions. It just crashes.

If you have a Guru Meditation Error or Backtrace, please decode it: https://github.com/me-no-dev/EspExceptionDecoder

@kbickham please decode the backtrace you have posted using the exception decoder in the issue template.

It would appear that you are attempting to access data from a null pointer. The decoded backtrace will point you to which code is causing it.

[kbickham]

I'm not using any explicit interrupt and don't believe I could be hitting cap on ram.

Apologies, I actually tried to go through and clean up some some stuff in the program and that's what I got. The decoded backtrace for above is actually:

From what I read..the ram usage is an issue for a lot of people? This version of my code isn't even utilizing any internet protocol of any kind, I was just reading from 3 sensors (mlx90614 ir sensors, as7263 spectrometer, and a loadcell through an hx711 amplifier/adc)

[atanisoft]

@kbickham the decoded stack doesn't match any of the code you have provided in this issue. It appears that sendGData() is attempting to use a null object in it's call to tcpip_adapter_stop().

[kbickham]

Changed my ide version/reinstalled tools and boards. May not be accurate...I have 24 hours to finish a project, I'll repost pertinent info asap.

[kbickham]

Pretty sure it was the dev version of wifimanager. I cut down the mem use and switched to only using a captive portal. Assuming I should go ahead and close this?
