I was also trying to use the IPv6 over BLE feature. However, this dongle only supports Bluetooth 4.0 and the one required is 4.1 at least. I carried on searching newer Bluetooth USB dongles, but I was unable to find them .
I've just bought a RevPI DIO. Is it possible to connect to any wireless (Wi-Fi, Bluetooth, XBee, etc...) module ? Can it be done using the USB port, for instance?
