I have a stm32wb55 as bluetooth serial device, and I can pair it with a phone and can get an output but on the PC with rfcomm it doesn't work.
I want an rfcomm alternative because it doesnt work and is also departed, I tried it on my rok 5b with armbian and my tower pc with archlinux. I tried to connect it with rfcomm and it didn't work. It closed after a few seconds with screen and picocom.
I want to use the output and input in a c++ program on my pc/sbc.
