Functional description
5.5.3
5.5.4
V1.2 detailed functionality - Faster connection
● User perspective - Faster connection
This feature gives the User about 65% faster connection on average when enabled
compared to Bluetooth spec 1.1 connection procedure.
● Technical perspective - Faster connection
The Faster Inquiry Functionality is based on a removed/shortened random back off and also
a new Interlaced Inquiry Scan scheme.
The Faster Page functionality is based on Interlaced Page Scan.
V1.2 detailed functionality - Quality of service
● User perspective - Quality of service
Small changes to the BT1.1 spec regarding Quality of Service make a large difference.
Allowing all QoS parameters to be communicated over HCI to the link manager enables
efficient bandwidth management.
Here after a short list of user perspectives:
1. Flush timeout enables time-bounded traffic such as video streaming to become more
robust when the channel degrades. It sets the maximum delay of an L2CAP frame. It
does not enable multiple streams in one piconet, or heavy data transfer at the same
time.
2. Simple latency control allows the Host to set the poll interval. This provides support
for HID devices mixed with other traffic in the piconet.
