It looks like the error may be related to a missing or incompatible binary for your Intel Mac. Try running M5Burner using Rosetta, or check if there’s an x64-compatible version of M5Burner available. Also, make sure you’ve given M5Burner full disk access in macOS settings. Reinstalling the app or using Terminal to manually erase and burn via esptool could also help.
@felmue Finally got it working correctly. In addition to your code, I initialised the Pahub, and then changed the dip switch to 0x71. Additional units work fine when assigned to 0x71.
Thanks for the help!
I don't recommend this product. This is what it looks like after being in a barely damp plant overnight! No wonder I couldn't get any readings! IMG_9390.jpg
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.
please stop posting incorrect / not very useful information. W5500 is different from ENC28J60 and therefore EthernetENC or UIPEthernet library cannot be used for W5500. Thank you.
It sounds like the battery may be dead or disconnected internally. Warning 22 usually points to a battery issue. Since it powers on with USB but not on its own, try opening the case carefully and checking the battery connection. If that looks fine, the battery might need replacing. You could also try a full reset by holding the power button for 6–10 seconds.
They need to be in close proximity. The magnet is on the outside of the case so it should be possible to get it off without opening it. On the inside there would just be the back of the plastic indentation.
I will try grinding a part of the edge of the magnet away with a dremel tool and then prying the magnet out with a screwdriver, but I am concerned about breaking the case, but I hoped someone else may have done it.
@ulver Thanks for your kind comment. Yes, I hope my work will generate more interest on the LLM Module Kit. Looking forward to seeing announcements of advanced projects on the LLM Module Kit here soon.
@ajb2k3 There was no previous firmware that I installed. This was an out-of-the-box installation. I downloaded the latest update - I think 2.2.7 - and that's when the problem occurred.
Also, when I went to press burn, there was no opportunity to erase before burning.
