Method and apparatus for registering new Bluetooth device
View Patent ↗An in-vehicle Bluetooth pairing method includes commencing an automatic Bluetooth connection procedure with a first user device when power is supplied to an in-vehicle head unit. A progress state of the commenced automatic Bluetooth connection procedure is checked according to a request of new user device registration. A disconnection procedure corresponding to the checked progress state is performed, and a pairing mode for the new user device registration is applied.
1. A Bluetooth pairing method for an in-vehicle head unit, the method comprising steps of:
commencing an automatic Bluetooth connection procedure with a first user device when power is supplied to the in-vehicle head unit;
checking a progress state of the commenced automatic Bluetooth connection procedure according to a request of a new user device registration;
performing a disconnection procedure corresponding to the checked progress state; and
switching to a pairing mode for the new user device registration.
2. The Bluetooth pairing method according to claim 1 , wherein the first user device is a user device having Bluetooth paired with the in-vehicle head unit before commencement of the automatic Bluetooth connection procedure.
3. The Bluetooth pairing method according to claim 1 , further comprising a step of:
displaying an automatic connection screen including a notification message notifying that the automatic Bluetooth connection procedure is being performed and an add new button for requesting the new user device registration on a screen of the in-vehicle head unit.
4. The Bluetooth pairing method according to claim 3 , further comprising a step of:
checking the progress state of the commenced automatic Bluetooth connection procedure when the add new button is selected.
5. The Bluetooth pairing method according to claim 4 , further comprising a step of:
cancelling the automatic connection procedure if the add new button is not selected.
6. The Bluetooth pairing method according to claim 1 , wherein the progress state comprises a state in which a link is connected and a state in which a profile is connected.
7. The Bluetooth pairing method according to claim 6 , further comprising a step of:
completing connection of the link and then disconnecting the link which is connected when the checked progress state is the state in which the link is connected.
8. The Bluetooth pairing method according to claim 6 , further comprising a step of:
completing connection of the profile which is connected and then disconnecting the profile which has been connected and the link which has been connected when the checked progress state is the state in which the profile is connected.
9. The Bluetooth pairing method according to claim 6 , further comprising steps of:
completing connection of the profile which is connected when the checked progress state is the state in which the profile is connected; and
disconnecting the profile which has been connected and the link which has been connected without attempting to connect the profile in a connection standby state when there is a profile in a connection standby state.
10. The Bluetooth pairing method according to claim 6 , further comprising a step of:
rejecting the connection request if a connection request from a second user device in the checked progress state is received.
11. The Bluetooth pairing method according to claim 4 , further comprising a step of:
cancelling the automatic connection if the add new button is not selected.
12. The Bluetooth pairing method according to claim 3 , further comprising a step of:
displaying, after the step of switching, a vehicle name and a passkey value on a user interface screen of the in-vehicle head unit if a connection request message from the new user device is received.
13. A non-transitory computer-readable recording medium comprising computer executable instructions which cause a controller to perform the method according to claim 1 .
