Compatible Bluetooth adapter for Kali Nethunter

Hi all,

I have recently installed nethunter on my Nexus 7, after much research iv found the internal WiFi and Bluetooth cards don't work too well and are not compatible.

The nethunter git hub page has details on WiFi cards which are compatible but the link for bluetooth appears to be dead. I have read the LM540 is compatible however the cheapest I can find is £60 which is alot more than I wanted to spend, it is also a little overkill for my needs as it's high gain which I don't really need.

Does anyone have experience of adapter which work? Or even if there's adapters with a certain chipset which I should look for.

Thanks in advance
