I am using a DOIT ESP32 DEVKIT V1 and the device/thing are online. I can view it working in the Device Status History window; however, all that it shows is a solid blue running graph of some kind with no variation. Just an inch tall blue horizontal bar, endlessly streaming in real time.
I can upload code revisions to the ESP32 board over wifi.
What I cannot do is view the Serial Monitor over wifi, which is all I really want to do (in addition to uploading code revisions).
I have never tried to use Serial in a cloud app, I doubt it would work. I have used a combo MQTT and serial library. You write one message and it goes out on Serial if attached but also as an MQTT message that I then view on my Pi4 MQTT viewer thingy.
If you need communication via the network, you'll have to implement that separately.
Since you are using Arduino Cloud IoT, you can use the "Messenger" dashboard widget, which provides bidirectional communication with the Thing, similar to the Serial Monitor:
Ok. I was hoping for a more simple solution (hence the subscription to the Cloud Editor).
I may yet refer to that technique for a future project. This one it's more a "fun to have" than anything to do with the core functionality of the sketch.
I'll give it a try.
Appreciate the rapid response so I didn't end up spending the next four hours trying to make it work.
