It’s remained in Safe Mode overnight, which is what it should do. The console event log was also open overnight for event logging and it’s clean this morning. The issue was either some Particle Cloud back-end conflict with our account, or there’s some oddities with my local router and/or ISP.
The very essence of Safe Mode is for a device to connect to Cloud, so when this device was getting booted off the Particle Cloud while running our user code, I opted to see how Safe Mode behaved. The cloud connectivity operated the same regardless of how it was running (Safe Mode or User Code). It would initially connect to cloud then drop connection after 30 seconds or so.
What made this so odd is we have other P-Series devices that were running the same User Code and they were all happily connected to Particle Cloud and doing their thing.
Strange behavior… a bit unnerving as our fleet size continues to expand.
