Frankly Bluetooth is user unfriendly as there are profiles and more to consider. You can't just pair it and be done.
I have no idea what an Argus bluetooth 4 is (google that and didn't find one thing or the right thing?)
When I pair with my phone I do so over a SPP (profile) there are others and well, I have to install some app for the phone to sync with. I suggest you demand support from all the parties or start packing and getting refunds.
Bluetooth 4 is supposedly standard in this machine but it does not seem to be present, so I purchased Argus bluetooth 4 and plugged the dongle in.
Despite a couple of months experimenting I cant get it to work. I have a bluetooth receiver which will pair with my phone and works well. But try it with the computer and ....zilch
Try to find the reason and the computer insists either that I have not switched it on or alternatively that the user has disconnected it. There is no switch on the dongle, a blue light is on so we know it is working but can't get any further.
Anyone got any good ideas?
