Product is as advertised and works as it should.
OK!
The seller is trying to help me, but the Bluetooth CAT Interface is defective. We tested with Yasu FT 817ND, FT 817, FT 857D. Bluetooth connects randomly and disconnects itself, the software crashes. We tried another Bluetooth CAT Interface which is in a black box with a wire and a connector, everything works fine. I'm throwing away this Bluetooth CAT Interface, and I'm going to buy one that's in a box with a wire and a connector.
