Device cannot reconnect upon exhausting a battery

[dotchetter]

Describe the bug
Intermittent issue with the device, where on battery upon charging after complete depletion the device will not
connect to Arduino IoT Cloud but appear to work normally otherwise.

To Reproduce
Let the device exhaust a battery without USB plugged in.
Charge battery separately.
Plug in battery to the device to make it start up.

Expected behavior
The device boots up after a newly charged battery is connected and functions normally by connecting to Arduino IoT Cloud as expected.

The issue seems related to UART, where debug prints in the ArduinoIotCloud library can soft lock the device if no UART reciever is
detected on USB. This is purely speculation, but repeatedly proven in tests and provocation.
