IoT air quality checker device never connects to iot cloud

[quetzlthethird]

I've never done electronics and wanted to give it a try. So, I got the /iot-air-quality-checker-bundle and then followed the step-by-step guide exactly.

Device works great except that it does not connect to the IoT Cloud. Under devices, its always listed as "offline". I've followed the troubleshooting guide and deleted/ re-associated the device and thing multiple times.

Code is identical to code in the step-by-step guide (except for the thingID and network details)

Any advice on how to debug this would be appreciated!

Hello!

Did you check the serial monitor output? Did it print the message "Connected to IoT Cloud"?

@eclipse1985

"Connected to IoT Cloud"?

It does not print that message:

This is not the serial monitor output, it's the compilation/upload output. Check here how to open it (see " 7. Editing the Sketch" section)

[quetzlthethird]

of course its something so basic.

device could not connect to the wifi. I retyped the name/password and this time I did this it fixed the issue. device connects and is writing to the dashboard. thanks @eclipse1985 !

Great! Glad to hear you solved your issue!
