The BC127-EXT is pin to pin compatible with the BC127 and has the same form factor and functionality. The difference between the BC127 and the BC127-EXT is that the BC127-EXT has Pins for an external antenna while the BC127 has an integrated antenna. The BC127-EXT is useful when the application requires an external antenna (for example to keep away the antenna from metal surroundings). Similar to the BC127, the BC127-EXT provides the following:
BC127-EXT is the newest generation of fully integrated Dual Mode Bluetooth and Bluetooth Low Energy (BLE) modules. BC127 offer better performances in every single aspect to the older Bluetooth Classical Modules:
Smallest Package: BC127-EXT comes running all the Bluetooth Stack and Codecs in a very small form factor at 11.8mm x 18mm. BC127-EXT comes with Bluetooth certification so customers will not need to have to go through certification if they use a certified reference design.
Highest Performances: BC127-EXT offers Bluetooth Low Energy and very low power consumption in every use case (<60mWatts while streaming music, <3mWatt connected Idle).
Audio Quality: BC127-EXT integrates all high quality Audio Codec such as aptX, AAC, MP3 and SBS high definition In addition the user can configure the module to transmit the Audio received via a high quality integrated Analog Codec (96dB SNR) or directly to a digital interface at a chosen configurable sampling rate.
Fully Integrated: BC127-EXT comes with Melody and offers a high level UART command interface that provides full control of all profiles needed such as HFP1.6 (Wide Band Speech HandsFree), A2DP/AVRCP 1.4 (Music Streaming), PBAP (Access to Phone Book) and connects to Android and iOS devices.
