[SOLVED] Diagnose Bluetooth incompatibility between two devices

[Martin 8653]

I have a Logitech K380 keyboard with Bluetooth (3.0 BR/EDR), which I can use just fine with my laptop (3.0 BR/EDR) and phone (4.2 BR/EDR/LE), but not with my TV (4.2 BR/EDR/LE). The TV is a Samsung GU43TU8079 and has a system setting menu for Bluetooth keyboard and mice. The TV also recognizes my headphones (4.2 BR/EDR/LE).

Is there anything beyond the Bluetooth version and type (Classic BR/EDR and Low Energy LE), which must match in order to have the devices see each other?

theres no hidden magic for bluetooth, u put keyboard in pairing mode, then u connect to it with another device
for your tv u can add bluetooth devices from here:
Settings > General > External Device Manager > Input Device Manager > Bluetooth Device List
bt device will appear only if its discoverable (in pairing mode) or if its paired already it will be listed aswell

The Bluetooth version does not need to match for many devices, they are mainly backwards and forward compatible unless specified. But... that does not mean that some devices, chipsets, drivers, firmware, etc... won't have issues with talking to other devices, it happens. I've seen laptops that refuse to connect to some speakers/headphones but work with others or stability issues with only specific things.

I have tried it again and followed the menu again, but it just doesn't find the keyboard. I've uploaded a video of that.

So if it doesn't connect, there is just nothing one can do? It is just the way of Bluetooth that it just doesn't always work?

Did the keyboard come with it's own connector dongle for wireless or only Bluetooth? Often TVs with a USB port work with a wireless keyboard/mouse dongle connected to it.

That particular keyboard doesn't have USB. But I could try a USB keyboard with the TV.
