CC2564MODN: Bluetooth Module for Helicopter Infotainment System

Prodigy 20 points
Part Number: CC2564MODN
Other Parts Discussed in Thread: CC2564, , CC2564C

Tool/software:

Dear TI,

I am exploring Bluetooth module options for integrating into a helicopter and small aircraft infotainment system. Below are the key requirements and considerations for our application:

  1. Application Context:
    • The infotainment system will be used in helicopters and small aircraft.
    • Primary use includes streaming multimedia content and phone calls.
  2. Key Features Needed:
    • Support for streaming multimedia content from the infotainment system to wireless headsets.
    • Support for streaming audio from mobile devices to the infotainment system.
    • Dual role (master-slave) with bidirectional audio support (mobile device <-> infotainment system <-> headset).
    • Exclusion of direct mobile-to-headphone connections to simplify the user experience.
  3. Technical Specifications:
    • Latency: AptX-LL (low latency) or equivalent is necessary to ensure lip synchronization between audio and video (below 22ms).
    • Interface: Compatibility with I2S interface supporting plain PCM (uncompressed), stereo, 16-bit at 48kHz.
    • Simultaneous Connections: Ability to pair with both a mobile device and a headset simultaneously, routing audio from the mobile device to both the headset and the infotainment system.
  4. Additional Features:
    • Standalone operation without an external MCU, if possible.
    • Support for firmware customization to tailor the functionality (SDK).
    • OTA
    • Analog input/output support is a plus. 

I am looking forward to your response.

Best regards,
Emanuele Cardani

    Hello  Emanuele,

    The CC2564 would be the device that best fits your use case here at TI.

    It can support all the key and technical features you have listed.

    However it is a transceiver type device that will need a host MCU to run on top of. The CC2564 communicates to the host device via HCI commands and a Bluetooth stack. TI offers the Bluetopia bluetooth stack for free use and supports MSP432 and STM32 MCU hosts. The Stack also has Linux host support. The stack can be ported over to different MCU hosts but that endeavor would not be something TI would support.

    OTA would be possible depending on what MCU is chosen. The Bluetopia stack supports file transfer profiles.

    Another thing to mention is that the CC2564MODN is no longer able to be certified by the btsig for new devices, thus you wont be able to market the product as bluetooth certified as the 4.2 specification is now deprecated. However we do have the CC2564C which is 5.1 certified and not deprecated.

    TI does not sell a CC2564CMOD but there are 3rd party partners such as BDE that create some modules.

    Best,

    Thanks for your support.

    Besides the STM32 and the MSP, are there other officially supported MCUs like TIVA?

    About the latency, do you have report?

    Does the simultaneous connection support simultaneous streaming?

    I must route audio (music or phone calls) from the mobile to the Infotainment system and from the infotainment system (I2S) back to the connected headset.

    Best regards,

    Emanuele

    Hi Emanuele,

    Apologies for the late reply.

    Those are the only officially platforms supported for the Bluetopia 5.1 bt stack that is offered by TI.

    We do not have reports on latency I can offer you.

    Yes the chip does support simultaneous streaming.

    The last point is possible and has been done with many of our customers.

    Best,

    Rogelio
