I have Direwolf TNC running on my MBP and it talks wonderfully to my IC-7000. Now I want to connect it to my Kenwood TH-D74 HT via Bluetooth. I can 'pair' the two together but it only lasts for a few seconds before disconnecting. This makes it impossible for direwolf to find it. Has anyone successfully paired there D74 to Big Sure for a lasting connection, and if so how?
