Photon: green, cyan, red

Troubleshooting

The device does not show up in my AP’s logs so I too doubt it hits the cloud. I will test the server key asap. https://youtu.be/o7IqIUB5QFM

Video attached.

This looks like 2 “normal” orange not 1 quick red

I would try the Photon Cloud Debug firmware. That will log all sorts of information about your access points and the cloud connection, especially if you use the combined.bin method of flashing it. In particular, the details of the DNS resolution of the cloud server.

Nice tool Rick. Output below. I stopped it when it appeared to start repeating so I am only including data from the 1st loop.

Like I said cool tool - I modified my AP and now its making sense. The IP/gateway below is from my other location current should be 192.168.5.xxx This device has had its wifi table cleared at least 5 times why would this data be sticky?

Ah ha! Did you use a static IP address? That’s not cleared when you clear Wi-Fi credentials.

Or did you reserve and IP on the DHCP settings of the AP?

28

Rick & Paul, yes I used static IP but no I did not reserve DHCP.

29

Device is back online with Tinker and new static settings. Working fine - particle docs did hint to this “The addresses are stored persistently so that they are available in all subsequent application and also in safe mode.” shame on me for missing.

Thanks to all of you for helping resolve.

how did you clear the credentials? I also used a static IP.

31

I use this program to turn off static addressing:

#include "Particle.h"

SYSTEM_THREAD(ENABLED);

void setup() {
	Serial.begin(9600);

    // To switch back to dynamic IP, use:
    WiFi.useDynamicIP();

    // Turn on the D7 LED so we know the operation completed
    pinMode(D7, OUTPUT);
    digitalWrite(D7, HIGH);
}

void loop() {
}

To clear Wi-Fi credentials you hold down SETUP until the status LED blinks blue, and continue to hold down SETUP until it blinks blue rapidly, about 10 more seconds.

So I had to reconnect to the device to my network via the app. It worked! Strange that it didn’t recognize it from my stored devices.
