Hi all,
My team and I have been using the Particle Boron for a few years now in our products, and we have a device back from the field that is blinking green. We made sure to include graceful modem shutdown in our firmware to avoid this issue, as according to the previous app notes posted. Today I ran the cloud-debug code, courtesy of @rickkas7 (thanks for that helpful tool) on the device and got these logs back (attached below). Wondering if anyone might be able to provide some guidance on interpreting these? Thanks in advance for the help!
