EH-MB05 is a class 2 Bluetooth® 2.1+EDR (Enhanced Data Rate) module. It is based on CSR’s BlueCore5-Multimedia. With internal DSP and audio codec, it provides a fully compliant Bluetooth V2.1+EDR specification for data and voice.

With ehlink@ AT command stack through UART, designers can easily customize their applications to support different Bluetooth profiles, such as HS/HF, A2DP, AVRCP, SPP, HID and etc.And with the build in firmware the module can also be connected with Apple’s Authentication Coprocessor to build an iAP over Bluetooth application.
