I have a fairly new Boron (Device OS: 4.0.2) that until recently has been working just fine (I've been testing DHT sensors). I set it aside for about a week to work on something else. When I returned to work on the Boron, I noticed a few strange things. When I plug it in the USB port, it breathes cyan, and shows as online in the console as well as command line via "particle list". The "Last heard" and "Last handshake" in the console show current timestamps, but all other attempts to communicate with the Boron fails. I've tried Ping and Signal, and they both return "The device was unreachable by the Particle cloud within 15 seconds."
Any attempt to flash, upgrade, etc. via the command line fails. For example, when I try "particle serial inspect" on the command line, I get the following error:
%particle serial inspect
Device: e00fce683ec2aa070cf01e7c
Platform: 13 - Boron
Could not inspect device: Memory allocation error
For reference, "particle serial inspect" works just fine on my other Boron and a Photon.
Any ideas on what might be causing this, or other suggestions for troubleshooting? Thanks!
