Hi there, I've been having similar problem with the Create agent.
About a week ago I had a first try with the IoT cloud, everything went well and code was uploaded to my ESP32 easily. I tried again last night but my browser wasn't detecting the ESP32.
I can use the local IDE easily and upload/run code fine.
I have tried re-installing the create agent, and "Generate and Install HTTPS certificates", still nothing. I then tried installing the create agent on others' Mac computers, still nothing... Is something going on with the driver software?
After "Generate and Install HTTPS certificates", the create agent was being recognised at the end of the installation instructions, where as it wasn't before, but still no devices being recognised.
This is caused by a bug recently introduced into Arduino Cloud that affects ESP32 and ESP8266 boards. I have submitted a formal report to the Arduino Cloud Developers and will report back here if I have any news to share regarding a resolution.
For now, please use Arduino IDE when you need to upload Arduino Cloud IoT Thing sketches to ESP32 and ESP8266 boards via the serial port.
You can use the Arduino Cloud sketchbook integration feature of Arduino IDE 2.x to get convenient access to all your Arduino Cloud sketches (including Thing sketches) for use in Arduino IDE:
You can continue to use Arduino Cloud to set up IoT Devices, Things, and dashboards, to write and compile sketches, and to interact with the Thing via dashboards. The only problem is the inability to upload to the board via the serial port. The bug does not occur when using a non-IoT sketch so you can work with non-IoT sketches in Arduino Cloud, including uploading them to ESP32 and ESP8266 boards, just as always.
Thank you @ptillisch for your solution to this problem. I was able to get my Thing working by pulling my sketch in the Arduino IDE!
I hope they fix this problem as soon as possible.
Good news, everyone! The bug that caused Cloud Editor to not recognize the serial ports of ESP32 and ESP8266 boards has now been fixed. I apologize for any inconvenience this has caused you.
There is one remaining problem you should be aware of: if you have multiple Arduino boards (or other devices that produce serial ports) connected to your computer, Cloud Editor might pick the wrong port to use. I have submitted a report about this problem to the developers. For now, please disconnect any additional Arduino boards from your computer before opening an Arduino Cloud IoT Thing sketch in Cloud Editor when using a serial port to upload to the board.
Please give it a try and let us know if you still have any problems.
