Part Number: NX.KCWAA.001
Greetings, I'll ask this question in the Google ChromeOS forums too, but I doubt the answer will be what I want to hear.
I'm a bit of an electronics hoarder and traditionalist, and I've been using an ancient "Belkin F8Z492" Bluetooth audio sink dongle. It's AC-mains powered by a wall wart, and it converts BT output into 3.5mm wired audio, for speakers, headphones, whatever.
Since it's so very old, I suspect that newer Bluetooth implementations are incompatible, or refuse to pair with this device. My phone won't seem to recognize it, although Windows 10 on a 2018 Lenovo still works.
Literally, the symptom is that the Belkin does not appear on any scan. I can't see it, so I couldn't pair or connect if I tried. Even if I ask for it by name or address. Yes, the dongle is always "BT visible" to other devices. Yes, I've eliminated the question of interference or signal strength, of course; the difference in visibility is very noticeable between the two types of devices. In fact, a neighbor was able to pair their phone quite easily to it through walls, 'cause there's no security feature on this device. I've got clear line-of-sight and limited RFI, although this is a busy community with a lot of WiFi and BT signals in the air.
Is this a compatibility issue, or is there something else I can do to get this working?
