SPK-A Bluetooth module is  also based on OVC3860, which  is designed for product design of Bluetooth speakers. The characteristics of high integration, small size, just with a few external components will be able to achieve its powerful features. With A2DP, AVRCP transmission and remote control protocol any Bluetooth audio device (such as: Bluetooth-enabled mobile phone, computer Bluetooth adapter, etc.) to establish a connection, to achieve high-quality stereo audio stream wireless receiver, and audio player remote control. BLK-MD-SPK-B Bluetooth stereo receiver module to the user interface, remote control buttons work the status indication interface, stereo audio output interface.

Compared with BC05B

  • SPK-B just supports Bluetooth V2.0+EDR , BC05B supports Bluetooth V2.1+EDR
  • SPK-B is cheaper
  • SPK-B supports Power-On auto paired , but BC05B need software Power-Down and Power-On ,then into auto pair mode.

 

ultra-long-range Bluetooth module designed for ultra-long-range wireless data transmission and build using CSR’s BlueCore4-Ext chip follow V2.1 + EDR Bluetooth specification. The module supports UART, USB, SPI, PCM, SPDIF interface, support for the SPP Bluetooth serial protocol, with advantages of low cost, small size, low power consumption, the transceiver sensitivity high transmission distance, just with a little external components will be able to achieve its powerful features.

Max distance up to 200 meters with IPEX interface 24DB antenna. Use 5DB antenna about 50-70 meters.

    I have purchased a BLK-MD-SPK-A module for installation in a Hi-Hi amplifier to receive Bluetooth signals from a Laptop PC. I have fitted it and it is powered by 5v DC. I need automatic connection i.e. (no buttons or commands) which the unit apparently supports but I can find no information about how to enable this function. Can you help.
    Thanks
