I teach an IoT course using the Particle Argon’s. Several of my students are having the same issue. After flashing code, the Argon goes to blinking Green, then blinking Cyan, but never moves on to Breathing Cyan. We find that if we unplug from the USB port and replug in, then it goes through the sequence correctly to connect to the Particle Cloud.
I have had them follow the directions in: Device Blinking Cyan – Particle Support.
Basically we are doing this to update the keys:
- put your device in Listening Mode (blinking blue) - hold Mode button for 3 seconds
particle identify(note device ID)
- put device in DFU Mode
particle keys doctor <insert your device id>
- put device back in DFU Mode
particle keys server
- tab the reset button once
This has not fixed the issue.
(Also, is there a way, if I send the device ID to someone at Particle that they can look at the Cloud log to see why the connections are always working?)
