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.

Hey,

I haven’t run into that issue, it might be best to do a copy-paste into the Particle support forum. I’d be interested to hear what the way forward was.

Does core not support this through local (AU) warranty?
