T-BEAM V1.2 with AXP2101, battery charging.

[AndRZJt1]

Good morning,
I have T-BEAM V1.2 with AXP2101
I have a problem with displaying battery voltage and charging the battery.
After connecting the charger, the charging LED does not light up.
I have the following software installed: master_v0.9.4-B17-full

Please let me know if this problem can be solved.

Thank you and best regards

Hello, I have the same board and iam having the same or similar problem. The Battery status page does not show any information, no voltage, no temperature, or anything else.
Is there any solution for this please?

Thank you, Libor

Yes, may I ask you, is WiFi working on your T-Beam with the binary firmware image?

I have one T-Beam 1.2 now for testing, but I have the issue that it does not connect to an WiFi network (but WiFi works in AP mode). Changing the bootloader to 40 Mhz flash SPI (instead of 80 Mhz) eliminates the problem, but I do not understand why.

Also my travis CI credit for building the images has expired. devel20240419 is available as source (and should show voltage on the T-Beam 1.2) but not yet tested, and not yet built as ready to use image.

ok, thank you for the clarification.

@alx6ths can you send the compiled version (devel 20240514), I can't cope with the Arduino IDE configuration.
Thank you

@AndRZJt1 Hi, I'd love to help you with this, but I'm in a similar situation with Visual Studio Code and unfortunately I don't have such a file. The firmware file created during compilation is about 4 times smaller and cannot be used separately with the Flash Tool. I compiled it and uploaded it directly in Visual Studio Code. A friend helped me with it and I'm glad that it somehow worked out in the end.

Maybe someone can advise how to create a working bin file...

Its now available on the download page as binary image (and as update)
