Operation Description Basic Description: Bluetooth requires each of the Bluetooth communication between devices when a main role to be, and the other from the role in order to communicate, communication, it must be carried out to find the host to initiate pairing, after the uccess of the construction chain the two sides can send and receive data. A Bluetooth communication device that can switch between the two roles, usually working in slave mode, wait for the other master device to connect, if necessary, change the main mode, a call to the other devices. The main mode of a Bluetooth device to initiate the all, you need to know each other's Bluetooth address, and other information atching, matching is completed, initiate the call directly. 1>, The Square Bluetooth supplies A2DP and AVRCP profiles.The working requency is 2042MHz~2480MHz. It contains 79 channels. The frequency of its main ontrol chip is 16MHz. 2>,The audio is output via 16 ohm headphone speaker . 3>It is connected to DC 5V power charge via the Micro USB cable.

The complexity of the technical specifications, however, means that full and thorough testing is impractical for both technical and economic reasons. Furthermore, there is no guarantee that a test sample which has passed all the relevant tests conforms to a specification. Neither is there any guarantee that such a test sample will interwork with other genuinely open systems. The existence of the tests nevertheless provides the confidence that the test sample posses…
