MS Transceiver

I needed to repair the Bluetooth transceiver in my Samsung 4K Chromebook. I started experimenting with a rusty MS Transceiver that I thought it might be a Bluetooth compatible. 

But it wasn't. Instead, my Apple mouse started to connect and work. Regular BT mice didn't connect, for like 2 years.

this one is an ancient 56 k modem

This is it, a little rusty and crappy "transceiver" dongle

it started the recognition of BT mice by my defective inner BT transceiver. I don't have an old RF MS mouse to check does it work or not.
