[Bluez-devel] SSP testing and BlueZ

[Bluez-devel] SSP testing and BlueZ

[David Stockwell]

While attempting to test SSP with 3.34-3.35, I found that I was unable 
to pair with SSP; I was able to pair with the legacy 
pin-request/response mode.  I checked the HCI level of my aging BT 
dongle (somehow this sounds a bit "dirty"), and found that it was only 
HCI 1.1 compliant.  Replacing it with a BT2.0+EDR compliant dongle, I 
found that it still would not pair with SSP.

Consulting with CSR, they confirmed that unless both devices are 
Bluetooth HCI 2.1 compliant, SSP will not work; it will always fall back 
to Legacy pairing.

I searched yesterday for HCI 2.1-compliant dongles, and found only one, 
from Logitec (not Logitech) in Japan.  These are not available in the US 
market.

So much for SSP testing, for me at least.  Fortunately for me, my app 
does not need this enhanced security...

you can update CSRs BT2.0 with 2.1 Firmware. That should work. I think
you can download the firmware on the csr support site.

I will give this a shot.  Thanks.  Will also need to see if my even 
newer dongle can be upgraded.
