I've bought a second hand arduino bt-v06.
When I connect it to the power, led 13 turns on.
But if I try to add a device to my Windows 7, I can't find it, even my phone can't.
Is it a problem about visibility? I don't know what the previous owner programmed.
Even when the Arduino boots, it isn't visible.
I don't have a programmer to reset the bootloader.
Okaay, I've finally got it working.
The problem was probably caused by a wrong power supply.
The label on the adapter said 5,0 V DC, but I guess that was a mistake.
When I replaced the power supply by another adapter, 4.5 v, the bluetooth device appeared.
I don't have a multimeter to test the adapter at the moment, but I guess it doesn't work correctly.
Good luck with fixing your problem!
