Any updates on this ?, does anyone know when this will be working again?

Thanks,

@toffifee The raw outputs are beyond the ken of mortal man, except Accel which can easily be observed by placing it on a stationary level surface and observing that the accel values are stationary and one of the axes, usually Z is showing 1.00 (gravity).
Roll it onto its side and the 1.00 should move to another axis.
The other two outputs Gyro and Mag are best left to a positioning algorithm.

Hello @paydogs

my M5PaperS3 running the factory test shows about 4.19 V when fully charged and still on USB-C. When I remove external power it drops to about 4.12 V.

The soft reset seems to do the job (12 hours of measurements uninterrupted)

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 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.

Hello @scroggyg

the added 5 V power switch I use to fully turn the modem off when I want to use M5Tab5 without modem (without the need to de-solder it.

The other modification to control the POWERKEY of the modem via GPIO (instead of the default auto power on) of the modem is required for two cases:

firstly to restart the modem in case it becomes unresponsive to AT commands and secondly to get it out of PSM (power save mode).

Thanks

Hello @scroggyg

in UIFlow2 under Hardware you can find the Watch Dog Timer (WDT) module.

I created a example in the UIFlow2 Project Zone: M5Tough_Watchdog_Test_UIFlow2.2.8

Thanks
Felix

@Felix22 @hacxx
it will support in the future!

Hello @hacxx

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.

Thanks
Felix

Hello @hacxx

please refrain from posting in year old threads which are already resolved. Thank you.

谢谢你的详细反馈，确实非常有价值。你提到的问题确实容易让初学者误解，尤其是在使用不同型号（如Atom Lite vs Atom S3R）时。建议文档中明确标注不同设备的引脚差异，并在示例代码中加上你说的注释说明，能大大提升用户体验。希望官方尽快更新网页和示例，减少后续用户的困扰。再次感谢你的分享！

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.

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.

UIFlow2 can feel odd due to inconsistent block behavior, limited error feedback, and occasional cloud sync issues, making it tricky for users to debug and manage projects efficiently.

@robmiles me, too. Acturally I bought two module. One is bought from first batch (with debug board), the other is from second batch. All use with Core 2 AWS. But the one of first batch LLM-module already dead (can't work anymore). Still can not find way to solve this.
