have now checked it with the second M5Paper but this can also log on to the WLAN and also syncronize. But just the first time, then I am also with this an active connection on the M5Paper displayed but in the WLAN of the router but he is grayed out (so no longer connected) and a second syncronisieren fails!

Have this morning the M5Paper connected to the WLan, which is displayed to me on my router and on the M5Paper.
But if I then go to "Sync Time" writes me the M5Paper WLAN not connected !?

Is there perhaps a bug in the software?

After I have reloaded the factory test software with the M5 Burner, logged into the network, set the time zone and then perform the function Sync Time works, but then I see how the M5Paper disappears again from the WLAN on my router and at another attempt with the function Sync Time the function no longer works!

It would be nice if I had it too. Unfortunately I can't find a supplier in Germany who delivers it.

Hello M5Stack Freaks,
Do any of you already have one of the new sensor Ampmeter Unit (ADS1115) or Voltmeter Unit (ADS1115) !

@felmue

You write (One thing that is not clear to me is whether the 18650C HAT can charge its battery on its own, e.g. w/o M5StickC installed. Does it have its own charging IC?)

The 18650C HAT is charged exclusively via the USB port, no M5StickC is required! The USB port is only for charging, otherwise the USB interface has no function!

@flatline69 ,

I just tested your setup, I have several M5StickC with blue 5V sticker and also two 18650C HAT.
I built the M5StickC with blue 5V sticker two pieces and the two 18650C HAT together and also screwed them together. But the M5StickC don't get warm!

Either, as @felmue writes, it is because of the charge current if it is not set to 100mA.
Otherwise it would be interesting which version of the 18650C HAT you have, because there are probably 2 versions of it. Unfortunately there is no version imprint in my version, but according to the documentation there should be no difference except for the additional mounting option.

So I guess in the end:

1. the charge current in the M5StickC is higher than the 100mA.
2. because you got an (Error 22) message that the internal battery is defective (deep discharge)
3. the M5StickC is defective (internal battery defective)
4. the 18650C HAT is defective, loose or defective components on the board lead to your result!

Good luck skink

@m5stack

Mh there are Barometric Pressure Unit (BMP280) & 6-Axis IMU Unit (MPU6886) supported, but what about the other units !

TVCO/eCO2 Gas Sensor Unit (SGP30)
Hall Effect Unit (A3144E Hall Sensor)
Voltmeter Unit (ADS1115)
Ammeter Unit (ADS 1115)

When are these units transferred to the UIFlow software !

Hello Felix,

Thank you, I have tested your program and it works perfectly. Thank you very much for that !
