I am wondering if anybody has deployed LTE Boron to remote sites and had them reliably stay up for months on end, and if so, 1) what Device OS you were using and 2) any tips/tricks to make this happen, short of an external power switching watchdog circuit. I ask amid extreme frustration as just thi…

The video explains whats going on better than me but yes you are correct, you have been using a software watchdog and not the hardware watchdog which is better. I’m not sure why they have not given us access to the hardware watchdog as the video shows you how to do but I’m sure there is a reason fo…

@RWB Thank you for this! I can’t believe that this isn’t common knowledge. Maybe I was the odd idiot and everyone else knew this, but I doubt it, because I’ve spent a significant amount of time on these forums and working with Particle Boron since May 2019, and I never until now knew that Applicatio…

I write this as I try to get the azure integration properly functioning (particle plaftorm is currently wrapping my json object in a string) for an industrial use case and this thread is worrying the hell out of me.

I didn’t find that video until a few months ago but then again I had put the IOT stuff down for awhile as I dealt with the curve balls life threw at me over the last 9 months. The Application watchdog is doing what I need it to do now and I haven’t needed to enable the Hardware watchdog yet but if …

@thrmttnw Thanks for sharing this. I had already read that thread and 1) concluded it didn’t help me, being unable to order custom PCBs and solder tiny SMD components, and 2) was unable to answer the following question: Are you saying that a Boron power cycle must be at least 30 seconds for it to h…

[image] Paul_M: Are you saying that a Boron power cycle must be at least 30 seconds for it to have a cleansing effect? From posts and my own experience 10 seconds is too little, 15 second may be just about enough so 30 seconds to be sure as according to the link quoted. [image] Paul_M: I…

Just wanted to chime in here and say, if you do go the external watchdog route, don't use the Deep Reset Tutorial posted above if you want maximum reliability. The EN pin has an inherent flaw, whereby it locks up the Boron if anything else that attaches to the boron can backfeed more than a minimal…

@hwestbrook Thank you for sharing this. I think you’re right: there’s no way to use Particle Boron LTE for reliable, permanent remote monitoring without having an external supervisory circuit that will depower/repower the Boron after a period of time goes by that the Boron doesn’t send it any “I’m c…

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:
