I make a product that includes a photon. The product is sold to our customers so I need some help without being able to do much myself in terms of adjustments or investigations into router settings, etc.
The issue:
The photon is able to wake up (device is battery powered and uses deep sleep) send reading, but the photon gets NO confirmation from server that a reading was sent. Furthermore, OTA updates fail. RSSI is reasonable at -65.
Attempted resolution:
Assuming it was an issue with the photon, I replaced the device containing the photon, but the new device behaves in the same way. Therefore I am assuming this to be a network configuration issue.
I have a two customer sites that seem to be affected by this issue. I have asked customers about routers and strange configuration settings. They claim to use a stock airport extreme. Any theories or experiences are very appreciated!
