    Define unique LED patterns for user actions, system states and events This document describes how the device can be configured and used. Figure 1.1 shows a possible user case for a multi-channel audio Soundbar (based on a CSR device with an 8670 IC wireless subwoofer speaker).

  • Page 6: Hardware

    These use either the CSR Bluetooth example CNS10001v4 (CSR8670) or DEV-PC-1645 (BlueCore5-Multimedia) design boards. Notes: A DEV-PC-1309 interface board and suitable SPI interface, such as a CSR 132 USB-SPI converter, is required to program and debug both BlueCore5-Multimedia and CSR8670 devices. 2.1.1. Backing Up the Development Board Before flashing the application to the hardware CSR recommends clearing all the PS Keys from the development board.

  • Page 7: Getting Started

    If using a BlueCore5-Multimedia device (DEV-PC-1645B development board), merge the subwoofer_configuration_1645.psr file. Select from the menu. Build Active Project (F7) Build Select from the menu. Run (F5) Debug The application is now running on the hardware. Page 7 of 28 © Cambridge Silicon Radio Limited 2014 CS-310152-UGP1 www.csr.com...

    LEDs), the remote device must discover and initiate pairing. The default restriction level has been disabled, so any remote device is allowed to pair with the ADK 3.0 Subwoofer. Page 22 of 28 © Cambridge Silicon Radio Limited 2014 CS-310152-UGP1 www.csr.com...

  • Page 23: Connecting With The Paired Device

    While the device is in connecting state and it is continuously paging the paired device, the amount of time between each reconnection attempt is configurable using the Application Features configuration, described by section 4.1, the default value is 10 seconds between each reconnection attempt.

The EQ banks can be configured using the CSR Universal Frond End application and then downloaded to the ADK 3.0 Subwoofer. 5.5.3. Wired Mode Volume Control When in wired mode, buttons are used to control the audio gain of the output signal.

    Configurable timers exist to allow the timers between each process to be changed to suit different hardware requirements. Section 4 describes the configuration options available for these timers. Page 25 of 28 © Cambridge Silicon Radio Limited 2014 CS-310152-UGP1 www.csr.com...
  • Page 26 For amplifiers that do not support MUTE I/O lines, a digital mute is applied by the DSP application (where the lowest possible gain is applied to the audio stream), this process is unlikely to take more than 10 ms which CSR recommends as the default configuration.
