Compiling code - Older compiled code will not work for MQTT but identical newer will - How is it possible?
We have a situation where we are connecting to AZURE IOT HUB
For some reason all our systems will go down and stop. Rebooting won't work, reloading the same firmware won't
If we then take our firmware and recompile it and push it to the device communication will work.
We cannot figure out how this could happen.
It is the same sketch just compiled at different times
The system can run for weeks to months
