I’m using Argons in a classroom, and I’ve had the following issue happen to two devices so far, and they have become unusable.
I can’t point to a specific cause, but the devices are operating normally and at some point there is a flashing error. From then on, the devices are always breathing cyan but flashing keeps timing out.
Here are some things I’ve tried:
- Flash device from Workbench and Web IDE while breathing cyan–device times out
- Put device into DFU and run
particle updatefrom CLI . This finishes normally, and I try to claim device again. I’m able to connect to Argon from iOS app, but after I select the wifi network, the app hangs at “connecting device to the internet via wifi”.
particle serial wifi. I’m able to input the wifi network and the device then starts breathing cyan. I can see the device as being online and I can even ping it (in the iOS app). However, when I try to flash it, it times out again (this happens from Web IDE, Workbench, or iOS app).
I thought it might be a bad device when it happened once, but now that a second device is unusable, I’m guessing something else is going on.
