We have a product that uses the Photon that is currently in production. Some of these devices freeze after a couple of hours of normal operation (in normal operation the photons are connected to the cloud). When the Photons freeze, they become unresponsive, and the LED is stuck in either solid green or off. After a power cycle, the photons appear to work fine.
According to this https://docs.particle.io/tutorials/device-os/led/photon/#solid-colors the firmware is getting stuck while connecting to the router (because it gets stuck while blinking green).
We are running system version 1.2.1 and are connecting to a WPA2-PSK network.
Has anyone experienced a similar issue or have any insights into what is going on here?
