Tearing hair out with simple WiFi

Postby dylanakbt » Tue Apr 03, 2018 10:05 am

This can't be as hard as I'm making it... I just want to respond to a GET request.

I have the esp32 connecting to a WiFi network just fine, and it's also running some BLE beacon scanning. I tried to use the http_request example code but whenever xEventGroupWaitBits fails the chip errors, aborts and I get some stack error...

Code: Select all

(path) (xEventGroupWaitBits)- assert failed!
abort() was called at PC 0x40090418 on core 0
There needs to be a simple way to do this. I assume I have the right example for what I'm trying to do. Can anybody point me in the right direction with this?

Pretty hard to say from those lines alone... can you post some more lines of the error (specifically a backtrace would be useful) and/or the crashing code?

For anyone stumbling across this post with a search, the problem was that I had forgotten this line (a little silly on my part!):

Code: Select all

my_event_group = xEventGroupCreate();
So I was waiting on an event group that didn't exist.
