Journey includes：First, the bluetooth connection unit of the first bluetooth equipment provides SDP services, and service describing, core are added in SDP services
The heart is to describe UUID and RFCOMM passages；Secondly, the bluetooth connection unit of the first bluetooth equipment and the second bluetooth are set
Pairing is performed between standby bluetooth connection unit；It is blue by the bluetooth connection unit of the first bluetooth equipment and second after successful matching
The bluetooth connection unit of tooth equipment sets up the SOCKET connections based on RFCOMM passages；After connection is set up, based on what is set up
SOCKET is connected, and RFCOMM is passed through by the bluetooth connection unit of the first bluetooth equipment and the bluetooth connection unit of the second bluetooth equipment
Passage carries out the up and/or downlink transfer of voice data；Wherein the first bluetooth equipment includes Bluetooth microphone, Bluetooth microphone
Earphone, Bluetooth audio device, audiphone, camera device；Wherein the second bluetooth equipment includes mobile phone, panel computer, laptop
Computer, PC, network machine top box.
To wherein be performed between the bluetooth connection unit of the bluetooth connection unit of the first bluetooth equipment and the second bluetooth equipment and matched somebody with somebody
To including：For ANDROID or PC systems, it is based only upon described UUID and RFCOMM Path Setups and plays the first bluetooth
Pair relationhip between equipment and the second bluetooth equipment, and for IOS systems, in the bluetooth connection unit of the first bluetooth equipment
Pairing is set up on the basis of inherently there is HFP/HSP and A2DP to service.
Wherein connected based on set up SOCKET, by the bluetooth connection unit and the second bluetooth equipment of the first bluetooth equipment
Bluetooth connection unit included by the up and/or downlink transfer that RFCOMM passages carry out voice data：For ANDROID or
For PC systems, based on the SOCKET connections set up, by the bluetooth connection unit and the second bluetooth equipment of the first bluetooth equipment
Bluetooth connection unit the up and/or downlink transfer of voice data is directly carried out by RFCOMM passages, and for IOS systems
For, in addition it is also necessary to a verification process, i.e., on the connections of the SOCKET based on RFCOMM passages set up, assisted by IAP1/2
After view is authenticated, EAP protocol is recycled to carry out the up and/or downlink transfer of voice data.
Further, RFCOMM passages can simultaneously transmit many line signalings, including multi-path audio-frequency data and control signaling.
Further, audio coding mode is Whole frequency band coding；Whole frequency band coded system include SBC, OPUS, Apt-X,
One of AAC.
Specific embodiment
