WI-FI Connectivity

All my 3 Photons got disconnected from Wi-Fi occasionally and shows a dark blue “breathing” light (even though there’s still a good signal and the router is very close).

I saw a few posts here with a similar issues but quite different.

Does anyone know a solution?

Many thanks

Breathing dark blue means the device network module (Wi-Fi for a Photon) is on, but not connected. Since there is no network, of course there is no cloud connectivity, either.

This mode can only be entered if the user firmware requests this mode. If the network is inaccessible, the device would be stuck in blinking green, not breathing dark blue.

The most common is a code path where you’re able to call WiFi.on() but not WiFi.connect() in SEMI_AUTOMATIC mode. If that’s not the cause, it’s hard to say without the source code or a detailed log when the problem is occurring.
