If anyone has time I could really use a hand…
I have a few questions to hopefully help me understand my incredibly frustrating situation a bit better. I am having the most awful time of it trying to figure out where my network instability lies.
Firstly, I’d like to say that my problems, frustratingly, seem to be random. I can’t marry up disconnects or packet loss with events on my network or with my “broadband” connection.
I’d also like to say I’m now running the Photons off a Ubiquiti UniFi AP…
Question: Does a recent
handshake timestamp indicate a Photon or a Core has disconnected and reconnected? Or simply that it’s “checked in”? Anecdotally I would say it indicates a broken cloud connection that gets re-established but I’d like to have this confirmed.
Question: would putting two Particle devices within two feet of each other affect their network stability?
Question: Why might a device go for a day with rock solid uptime (no recent handshakes) and then disconnect/reconnect every half hour until it’s physically reset with the reset button?
Question: How could I check whether my network has constant access to the Particle cloud? With a ping? I’d like to correlate failed pings to the Cloud from a computer with handshakes if poss…
Question: Anyone doing MQTT with a Photon - have you needed to change the default
#define MQTT_DEFAULT_KEEPALIVE from 15 to another number? I’m worried that in so doing I might give the impression of a more solid connection but in reality I’m just allowing for a more lossy connection and masking the problem?
EDIT: It’s super bizarre. So this morning, in my house, I’ve physically disconnected from power a Photon. THAT Photon has had a stable connection now for three hours. The other three, which were NOT disconnected from power, all have the exact same recent handshake of 10:59. I don’t get it… Same WiFi access point, all about equidistant from it.
