BTM51 series of Bluetooth module
As a kind of UART interface data cable’s alternative and audio transmission solution, this module can connect directly with the computer or other external processors, realizing transparent, wireless data and audio transmission among other devices like Bluetooth module, headset service, headset Gateway, Bluetooth mobile phones, Bluetooth PDA etc.
The Bluetooth module can establish connection with a single or multiple Bluetooth devices simultaneously for data and voice transmission. When more than one connection is established, the user can send data to a specified Bluetooth device as well.
Bluetooth BTM51 series module has security certification function. When the user sets and uses security certification, the device to be connected must do authentication. Only the users which pass the authentication can connect with the Bluetooth module. When need authentication, the module will indicate the user to input PIN code. If the module are set as automatic PIN code response model, when the user input the correct PIN code, this process can be finished by the module automatically, without user’s intervention.
