I’ve installed a Photon on a client site, ensured it connected to wifi, and ran it for one day before the internet connection gave out. The device tried to find a wifi connection (it was still available, PCs could connect to it) but remained on a flashing green status LED.
Shipped down a second micro controller, connected to the wifi, but after three days it started the same pattern going into flashing green LED mode.
The wifi is 2.5GHz, channel 1. Photon is powered by USB on a surge protector. The circuit is wired to drive a WS2812B array of LEDs. Using the Particle Cloud API to send commands, with a delay on requests so we don’t trigger an API limit (it’s currently set to 5s intervals at peak). I’ve ensured that both Photons are running on the latest firmware.
I understand that the Photon is 5V tolerant, but wanted to rule out that as an issue. If I unplug the LEDs I continue to have the same issue.
Any help is appreciated, would love to be able to solve this without sending down a third device.
