Hey look, thinking
is different than talking exactly
. First one give ideas. Second one misdirect..
I attaching a shot:
This glasses uses BCM20730 Bluetooth 3.0 chip
. I can't see any other chip (can't remove the plastic shield due cracking risk).
Bluetooth 3.0 is normal since this devices needed to save power. Bluetooth 3.0 has "Enhanced Power Control". But this probably means BT 2.0 sniffers doesn't work for capturing packets from this device. Or do they?
And unfortunately. there is no BT 3.0 eavesdropper. Or there is?
Also BT 3.0 features
Unicast connectionless data
Permits service data to be sent without establishing an explicit L2CAP channel. It is intended for use by applications that require low latency between user action and reconnection/transmission of data. This is only appropriate for small amounts of data.
I bet this goggles using this protocol.
When I connect glasses to PC's USB port, gives
Code: Select all
[302994.803057] usb 4-2: new full speed USB device number 98 using ohci_hcd
[302995.206138] usb 4-2: device not accepting address 98, error -62
[302995.206223] hub 4-0:1.0: unable to enumerate USB device on port 2
Means no go...
Anyway, I don't have any BT 3.0 device. It's selling from ~$5 at ebay
We could also eavesdrop BT device at TV with cheap hardware.
