just turn on the HS to be paired and wait for about 3~4 seconds, connection will autom atically be

Appendix
Q & A
1. What's the power on (when just plug in USB port) status? Is it idle?
What does dongle do in idle mode?
=> If the dongle remembered prepaired device, it will try to connect the prepaired device once power on.
When in idle mode, the dongle will be connectable. It means if prepaired device is trying to connet the dongle
at this time; the dongle is available for connecting.
2. What's the timeout of pairing?
=> The dongle is trying to pair any device which is in pairing mode. The pairing time is set to 1min.
3. When BT link's accidentally broken, i.e. out of range or strong interference. How does dongle re-act? If it tries
to re-connect, then how long will it try to re-connect before give up and switch to idle mode?
=> Dongle will try to re-connect the device. We can set the re-connect time, now it is set to 10min.
Dongle doesn't
try to re-connect to speaker, if it is a clean disconnect.
4. How many paired devices can dongle remember?
=> Dongle could remember many devices (we have verified remembering 8 devices OK). It could set as
requirement. Now it sets to remember 2 devices.
5. How is the paging device list process implemented?
=> If dongle has paired with a device, it will remember the device's bd_addr and password and authorization
information and store this infomation in pskey. The dongle will remember the latest device and move the other
device remembered back.
6. What's the definition of "Connection Lost: Clean Disconnect" and “Connection Lost: Dirty Disconnect"?
=> "Connection Lost: Clean Disconnect" means dongle know why the connection is lost.
"Connection Lost: Dirty Disconnect” means dongle don't know why the connection is lost.
