- In current implementation Autoconnecttimeout max value is
16384[0x4000] msecs.
- Since some controllers need some more time to respond to cmd
'LE Extended Create Connection' hence increased this
Autoconnecttimeout max value to 20480[0x5000] msecs.
For ex:
- In some controllers, If we include LE-Coded PHY in the initiating
PHY List, BLE INIT scheduler selects the 1M and Coded PHY scanning
as an initiator in round robin manner, and due to this available
bandwidth gets distributed between 1M and Coded PHY, and this
results in longer time taken for connection establishment by
the controller.
- If ref device is advertising at 1.5 sec intervals, with create
connection timeout of 4 sec, the controller gets only 2 opportunities
for the connection. Without the inclusion of LE-coded PHY,
DUT takes ~3.8 sec for the connection establishment.Hence as described
in above point with the inclusion of LE-coded PHY it is difficult to
achieve 100% connection success with the device having
adv interval of 1.5 sec.
Hence increased Autoconnecttimeout max value to 20480[0x5000] msecs.
