Firmware occasionally fails to parse setup POST #5
Description
When submitting WIFI data from the /setup page, saw this in the serial log:
_Unexpected Request : OPEN_POST / HTTP/1.1
Sending 404
The device then stopped responding to all further requests from the page. Wouldn't respond to further POSTS or to GETs at http://169.254.1.1. Nothing appeared in serial log. Only a hard restart of the device fixed it.
