I’ve got 3 initial prototypes which use an E0 (LTE) as the controller.
First one (top) is operating normally an as expected. Second and third are both nonresponsive and displaying a status LED pattern that doesn’t match anything in the documentation. I have validated that they are receiving the correct voltage (4.8-5VDC) and have tried swapping sources between the 3 and they retain the current behavior. Reset/Mode buttons do nothing except temporarily turn off the status LED. I cannot boot them into safe mode or DFU mode. I cannot reach them over serial w/ CLI.
Any ideas what might be happening with these devices?
