Unit ENV-Pro and Core2 for AWS

KC5JIM

I had this code (https://flow.m5stack.com/?examples=unit_env_pro_demo) working on my Core2 for AWS for several years. I re-purposed the Core2 for a short time, and now when I try to load the code with flow.m5stack.com, it says connecting for about a second, and the says disconnected. I have loaded UIFlow_Core2 1.14.4 with no problems. I have entered the API in UIFlow.

OK, it loaded, but when I select it under App and click on run, it restarts and comes back to the main UIFlow menu with App, Flow, and Setup.

And now it's back to saying disconnected in UIFlow. I've tried multiple USB cables and ports.

Any suggestions?

@KC5JIM Disconnected usually means that UIFLOW2 has lost connection to the server.
Have you erased the old firmware before burning the latest updated version for UIFlow2 for the AWS?

I have erased. This particular app is written in UIFlow1, so I've been installing UIFlow rather than UIFlow2.

It sounds like the Core2 isn’t maintaining a stable connection with UIFlow. A few things to try:

1. Reflash the firmware with the latest stable UIFlow_Core2 version using M5Burner, and ensure "Internet Mode" is selected.

2. Double-check that the Device Name/API Key in UIFlow matches what's shown on the Core2 screen.

3. Disable any firewalls or antivirus that might block the connection.

4. Try using UIFlow Desktop IDE instead of the web version for better stability.
If issues persist, test on another PC to rule out local system conflicts.
