Is there any way to communicate with UPS without disable RPi's bluetooth? #2

according to the README

we need to edit /boot/config.txt with enable_uart=1 dtoverlay=disable-bt

the second command will disable the bluetooth

how to use UPS_GUI_demo.py with bluetooth on?

On a raspberry pi4 this works. I am able to use uart communication and bluetooth enabled.

It is possible to enable the bluetooth and use the UART port located at /dev/ttyS0 instead of /dev/ttyAMA0 for the UPSPACK, by fixing the video core frequency in /boot/config.txt.

enable_uart=1
core_freq=300

The reason is that the baudrate of the raspi's mini UART module is affected by the VPU core frequency. reference

The serial interface is not required in normal operation (shutdown_check.py), Only for firmware updates and demo programs.

I have both on rpi4 by adding another uart (only certain models of pi have these)

let me know if you need help with this config
