I recently purchased a PR55-21 Azure Gateway and several PR52-10A sensors for a new project, and I am having trouble getting the gateway to stay connected.
I followed the configuration guides for the gateway, and I can connect successfully to the WIFI network. When I save the configuration with the connection string and WIFI details the green light on the gateway will turn green for a few seconds, and then transitions to a steady blinking red light. When I check the IOT hub the device shows as disconnected.
I tried a factory reset, but that did not change anything.
I thought maybe it might be my WIFI network blocking ports, so I built a node.js project to simulate sensor communication to Azure IOT hub. I ran that on the same network with the same Azure connection string and that was able to send telemetry normally, so I think the WIFI network is not the issue either.
Is there anything else I can check to troubleshoot the issue I am having? The gateway config is basic, DHCP enabled, Azure connection string and WIFI network information.
It is just a steady blink, no pattern of flashes.
When I exit configuration mode it will stay a steady green for several seconds, then a steady blinking red.
I do not think that the Wifi network or azure connection string is wrong, I have triple checked that.
I can see a connection being made on the access point for the WiFi, and can get a connection in azure for a second.
I build a node.js project to test the connectivity and on the same wifi with the same azure connection string that works perfectly, which is why I think it is something with the gateway itself.
Also, the issue I am seeing matches the issue Here perfectly and that turned out to be an issue with the gateway itself.
