Tips for deploying reliable LTE Boron that stays up

[thrmttnw]

A search on HW watchdog may reveal that it has not been enough to secure reliability in the past for the Boron. In addition the Boron needs a 30s power down capability to be sure, like this example here:

Deep Reset Tutorial

This tutorial is a simple example of how to use the EN pin on the Argon/Boron/Xenon to power down the device for around 30 seconds. Say you have a Boron in a remote location. The device knows it’s having trouble connecting to the cloud. Maybe power cycling it would help. This simple circuit powers off both the modem and the nRF52 MCU using an external timer. Pulling the EN line low turns off the load switch powering the modem and the nRF52 MCU on the Boron. On the Argon and Xenon it powers off…
