I manage a small fleet (~200) of Electrons running 0.7.0 DeviceOS. They are installed all over the country and I don’t have access to the devices. The Electrons are powered by a 5V, 2A power supply.
Some of the Electrons are offline (11 devices) and when I enquired about the device state, they informed me that it is blinking cyan. I confirmed this by looking at the video. It is a slow blink. I asked the person to do a power reset and it is online now. I repeated the same to other devices that are offline. They are also online now.
I am running
DeviceKeyHelper to restore device keys and I also have an application watch dog to reset the device if necessary.
- The slow cyan blink tells me that the device is connected to the network but failed to connect to the Particle cloud.
- A power reset seems to fix the problem.
- The problem seems to persist on one or two devices i.e. they do come online but disappear after sometime.
I am trying to find the root cause of this cyan blink and a potential fix for the problem. I am trying to avoid irritating strangers on the phone by repeatedly requesting a power reset.
Any suggestion is appreciated. I am not entirely sure if it is my code that is causing this problem as I am operating the Electron in semi-automatic mode.
