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.

Thanks
Felix

Hello @paydogs

I was just about to suggest that from your video it looks like the battery might be flat.

Glad you figured it out.

Thanks

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 @kuriko

thank you for this information. I just retried M5StampPico with UIFlow1 and changed the Start Mode to USB Mode and back to Internet Mode. In both cases I get the blue light. So I guess it's not connected to the server.

Thanks
Felix

@marnix201
The blue LED indicates that it is currently working in USB mode or is not connected to the server

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 @marnix201

I can confirm there seems to be an issue with UIFlow1 firmware for M5StampPico as I get the same result: solid blue light.

I also tested with M5AtomLite / UIFlow1: same issue - blue light.

However when I use an M5StackCore it connects ok to UIFlow1.

Note: above tested with UIFlow1 firmware 1.14.5

BTW: Any reason you are using UIFlow1? I tried M5StampPico with UIFlow2 and that worked for me.

Thanks
Felix

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
