[Bluez-devel] Re: Bluetooth and HAL

[Paul Ionescu <i_p_a_u_l@yahoo.com>]

Hi Marcel,

I'll remove the ChipVersion then, and I have some more questions:
How do we tell if we have a BT 1.0 or BT 1.1 or BT 1.2  adapter ?
By looking at HCI and LMP numbers ?
Do we need a separate bluetooth.version too ?
Do end user programs really need HCI and LMP version/revision ?


Thanks,
Paul
