Part Number: CC2564C

Hi Team Bluetooth,

My question is about the various versions of CC2564 and what level of BT-SIG Spec they are "compatible" with .. and which level of BT-SIG Spec "features" they each support.

For example.. the CC2564C is billed as “Bluetooth® 5.1 with Basic Rate (BR), Enhanced Data Rate (EDR), Low Energy (LE)” so it’s “compatible” with BT5.1 but I know it only supports BT4.2(?) features.. right?

I suggest that the web "titles" and datasheets be updated to provide this info.. for example for the CC2564C.. change it to..

CC2564C: Bluetooth® 5.1 Compatible (providing BT4.2 Feature Support) with Basic Rate (BR), Enhanced Data Rate (EDR), Low Energy (LE)

Please fill in the following table.. fixing inaccuracies and filling in the missing info “??”..

CC2564:

Web (www.ti.com/product/CC2564 ) says: “Bluetooth® 4.0 with Enhanced Data Rate (EDR), Low Energy (LE) and ANT”

BT-SIG Spec version it’s “compatible” with: BT4.0

BT-SIG Spec version “feature support”: ??

Stack/SDK version required to get this latest level of “feature support”: ??

Link to Stack/SDK version w/ latest level of this “feature support”: ??

 

CC2564A: Seems to be a Non-Existent Device

 

CC2564B:

Web (www.ti.com/product/CC2564 ) says: “Bluetooth® 4.0 with Enhanced Data Rate (EDR), Low Energy (LE) and ANT”

BT-SIG Spec version it’s “compatible” with: ??

BT-SIG Spec version “feature support”: ??

Stack/SDK version required to get this latest level of “feature support”: ??

Link to Stack/SDK version w/ latest level of this “feature support”: ??

 

CC2564C:

Web (www.ti.com/product/CC2564C ) says: “Bluetooth® 5.1 with Basic Rate (BR), Enhanced Data Rate (EDR), Low Energy (LE)”

BT-SIG Spec version it’s “compatible” with: BT5.1

BT-SIG Spec version “feature support”: ??

Stack/SDK version required to get this latest level of “feature support”: ??

Link to Stack/SDK version w/ latest level of this “feature support”: ??

 

For Reference:

 The CC2564 Datasheet (www.ti.com/lit/ds/symlink/cc2564.pdf ) only seems to say..

Changes from CC2560A and CC2564 to CC2560B and CC2564B Devices

The CC2560B and CC2564B devices include the following changes from the CC2560A and CC2564

devices:

• From a hardware perspective, both devices are pin compatible. From a software perspective, each

device requires a different service pack. When operating with the two devices using the supported

Bluetooth stack, the devices are integrated seamlessly and use remains identical for each device.

• Assisted mode for the HFP 1.6 (WBS) profile or the A2DP profile to enable more advanced features

without using host processing or power

• Support for the H5 protocol in the UART transport layer using 2-wire UART

• Enable 10 Bluetooth LE connections

Thanks, Merril

    Merril,

    There are a lot of questions/topics here. 

    - We are BT 5.1 compliant for both CC2564C and WL8, not compatible.  The TCRL2019-1 test suite that we passed indicates that we are compliant.  The features that are supported are not necessarily based on BT spec.  All new features when going from one BT spec to the next are considered optional.  The features that we support on our Dual mode BT devices are still in line with what we had supported with BT 4.2.  The only way to tell which features are supported is to look at the ICS details of the BT certification listing (QDID).  There you can see a line-by-line list of the supported features. Please refer to look https://launchstudio.bluetooth.com/Listings/Search and look at QDIDs 145296, 156966, and 156961.  

    - HFP 1.6 WBS and A2DP can be used simultaneously.  A2DP doesn't use the coprocessor, but A3DP does.

    - HW flow control should really be used, so H4 is required.

    Regards,

    Travis

    Hi Travis,

    Thanks.. This is still a bit confusing.  How can I tell..

    1. The max MTU size supported by each of the CC2564/CC2564B/CC2564C devices?

    2. Which stack versions are supported and which is the latest (and compatible) version for each of the CC2564/CC2564B/CC2564C devices?

    Thanks, Merril

    Hi All,

    Some add'l info from the factory on MTU sizes and stacks..

    1)      WRT ATT MTU size right.. this is stack dependent. With Bluetopia stack (ATTTypes.h)

       /* The following constants represent the minimum and maximum         */

       /* (respectively) MTU values that are allowable for the Attribute    */

       /* Protocol.                                                         */

    #define ATT_PROTOCOL_MTU_MINIMUM_LE                                 23

    #define ATT_PROTOCOL_MTU_MINIMUM_BR_EDR                             48

    #define ATT_PROTOCOL_MTU_MAXIMUM                                    517

     

    2)      Stack Versions – WRT Bluetopia stack versions.. The BT5.1 updated Bluetopia stacks are not yet publicly available.  Currently, released stack for CC2564C (BT4.2) and CC2564B (BT4.0) are -
