CC2564C: Data rate and transmit power configuration

Max Shaffer

Part Number: CC2564C
Other Parts Discussed in Thread: CC2564

We are using the CC2564C/Bluetopia stack in Classic mode with the A3DP profile to stream audio.

Is it possible to configure Bluetooth stack such that the CC2564 will not use EDR2 or EDR3? If so, which function calls should I use?

Is it possible to set a maximum transmit power (say +4dB)? If so, which function calls should I use?

Thanks!

    The Bluetooth stack does not have control over which modulation type is used for data transfer. The modulation type used by the controller for a given connection would depend on the remote device's capabilities (a.k.a. feature set) and the local device's network topology. For the CC2564C controller, selecting the appropriate modulation type for any given connection is handled internally to the controller without any stack level API. That being said, why would you need to disable the fastest modulations in the first place?

    You can use the VS_Set_Max_Output_Power API from the BTVS.c of the TI dual-mode Bluetooth stack for this.

    Thanks for the reply Vihang.

    We have two Bluetooth radios in close proximity on our hardware. We would like to dial down the transmit power on the CC2564 and (if possible) change the modulation scheme to see how it affects our other radio.

    Follow up question: When would the CC2564 controller select EDR3 modulation?

    Thanks!
