You already know it doesn't but it's not about the dongle here. The dongle is the hardware and the pairing is done with software. Since it's mostly a software issue it's sort of the wrong question.
I find pairing to be a small minefield of requirements, drivers, settings and more. If you have only paired a few things or none, it's bewildering. If you have been pairing without trouble you may think this is alarmist.
My bet is that a good setup PC software and drivers will pair over this dongle.
I know it's a hard concept but the dongle doesn't do the pairing. It's just a radio.
I have tried to pair Act2fit on my desktop wit Trust bt 4.0 dongle with no success.
Has anybody got it working in similar environment?
Thanks in advance
