7. Some Key Points That Our Opponents Can’t Do

a. DSP

 

The voice collected by the mic and the voice signal from the far end is mixed, filtered and strobe processed in DSP, then played by local SPK, and also needs to be transmitted to other devices through RF channel. DSP processing is also the core difficulty of the whole project. The difficulty of full-duplex intercom lies in not only letting others hear their voice, but also not being able to hear their voice locally, making the voice heard by others clear and low delay, and also considering reducing environmental noise and other issues. These problems are related to the knowledge of digital signal processing, Kalimba DSP programming, and so on.

          b. Bluetooth Pairing

 

Bluetooth pairing. The process of discovery, pairing, and connection between Bluetooth earphones are not very different from that between mobile phones and ordinary Bluetooth earphones. Because our scheme supports the function of shareme, the API for scanning and connecting other sink devices can be found in the sink routine (refer to sink “inquiry. C). When the master device enters the inquiry mode, the slave device enters the condisc mode, and the master device finds the slave device and initiates the connection request to complete the pairing. Note that the main device may be connected to other non-Bluetooth intercom headset devices, so you need to filter the searched devices during the inquiry process. The filter condition can be a device name or a profile type supported by the device. The latter method is adopted in this project.

c. Networking Tech

The scheme supports the connection of up to two devices at the same time, so the headphones can be connected in series by cascading. A reference application framework, namely TWC function (three-way conference), has been given in CSR ADK, but there is no special DSP processing. We can do it.
