As a kind of UART interface data cable’s alternative and audio transimission solution, this module can directly connect with the computer or other external processor,realizing transparent,wireless data and audio transimission between other devices like bluetooth module, Headset service, Headset Gateway, bluetooth mobile phones,bluetooth PDA etc.
The Bluetooth module can establish a connection with and a single or multiple Bluetooth devices simultaneously for data and voice transmission, when more than one connection, the user can send data to a specified Bluetooth device.
Bluetooth BTM51 series module provides security certification functions, when the user sets and uses security certification, the connected device must do authentication, only the users which passes the authentication can communication with the bluetooth. When need authentication, the module will indicate the user to input PIN code, then user input the correct PIN code; if the module are set as automatic PIN code response model, this process can be finished by the module automatically, without user intervention.
