The master - slave relationship of Bluetooth communication
Bluetooth technology for each pair of devices between the Bluetooth communication, must be a main role, the other from the role in order to communicate, communication, must be found by the main side, initiated pairing, chain success, the two sides that Can send and receive data. In theory, a cheap bluetooth speaker can communicate with seven Bluetooth slave devices at the same time. A device with Bluetooth communication can switch between the two roles, usually working in slave mode, waiting for other master devices to connect, and when needed, convert to master mode and initiate a call to other cheap bluetooth speakers. A Bluetooth device in the main mode to initiate a call, you need to know each other's Bluetooth address, paired password and other information, pairing is complete, you can directly call.
Bluetooth call process
The Bluetooth host device initiates a call, first looking for a Bluetooth device that can be found around it, and the slave cheap bluetooth speaker needs to be in a ready state, such as a Bluetooth headset that requires keystrokes to enter a searchable state, Device to find from the end of the Bluetooth device, and from the end of the Bluetooth device to match, then need to enter the terminal device PIN code, the general cheap bluetooth speaker default: 1234 or 0000, stereo Bluetooth headphones default: 8888, there are cheap bluetooth speakers do not need to enter PIN code, such as NSP-228 Bluetooth speakers.
