Does anyone have any idea what could cause the following:
Two identical units - one works fine, the other doesn’t.
The one that is not working well takes forever to connect (green flashing) - sometimes not being successful for hours.
Both devices are running the same firmware and device-OS (currently 3.0.0, but also tried others without success)
However, when I download the cloud debug firmware everything works perfectly - the device connects within a minute (light blue glow) every single time - so obviously, the antenna, radio, and registration must be fine, right? The serial monitor, as far as I can tell, reports connectivity as expected.
But, when I download the custom firmware, the behavior described above is constantly present, and is identical regardless of various SYSTEM_MODE (with appropriate code for each) - but is only present on one of the two devices I have on hand. I am using SYSTEM_THREAD(ENABLED).
I hope someone here might have some insight, and I would highly value any pointers or suggestions!
