Purchased particle Boron and Argon in march this year, been using both in the exact same way and have both been flawless.
In the last two weeks, i noticed the i2c LCD connected to my Boron no longer shows anything on the display. I have spent 2 weeks testing, factory resetting, reflashing, trying example sketches, all to no avail. Device would receive flash OTA ok and via USB however the i2c bus seems to be unresponsive. As a last-ditch effort I have tried factory resetting the device but now it will not reconnect to the cloud dashboard. The sim shows as active but the device does not appear in my devices.
I am happy to try and get it connected to my account using CLI over serial but my main concern is that the i2c bus is in fact dead.
