UM-D-010 NDA Confidential DA14AVDDECT System Overview 2 Introduction Dialog's DA14AVDDECT module is a low power solution for wireless audio, voice and data applications in the 1.9 GHz DECT band. The module is also intended for users with little DECT experience, who wish to make a wireless audio system. 3 Features and benefits The DA14AVDDECT module is small and easy to use solution that can significantly shorten time to market compared to flat designs and save costs on expensive RF test equipment.

UM-D-010 NDA Confidential DA14AVDDECT System Overview 5.2 Software Architecture The firmware is provided as a binary, and the user application and NVS area are customizable for the end product. The user application can run either on the host MCU or on the embedded Arm processor (Co-Located or "COLA" application), which is shown in Figure 3. Figure 3: Software Architecture 5.3 Software Tools The SW tools provided in the Software Development Kit are shown in Table 2.
UM-D-010 NDA Confidential DA14AVDDECT System Overview 7 System Overview This chapter shows the high level block diagram of three different systems, which are based on the SW profiles listed in Section 5. The default settings of the example Cola application are used for the block diagrams. 7.1 Tour Guide System Figure 4 shows the high level block diagram of the Tour Guide system where FP is broadcasting audio up to 1024 PPs. Audio is encoded and transmitted by FP with a CELT codec.
UM-D-010 NDA Confidential DA14AVDDECT System Overview 7.2 Public Address System Figure 5 shows the high level block diagram of the Public Address system that can connect up to 4 PPs to FP at the same time. The setup shown in Figure 5 requires DQPSK modulation (or higher). The default example application uses DQPSK modulation where 4 PPs can connect to FP.
