CC2564B-EVM +MSP430F5529 experimenter board

Other Parts Discussed in Thread: MSP430F5529

Hi,

I am having some query regarding the profiles I need to implement in the Bluetopia stack with MSP430F5529 and CC2564B dual mode bluetooth. I am trying a proof of concept here where

1. A TMP006 temperature sensor is interfaced through I2C and sends the data via BLE (SPPLE profile) on CC2564B.

2. It is also capable of transmitting audio through the CC2564B (classic mode) taking the audio sink as my reference design.

Now the problem I am facing is to implement both the SPPLE(for temp. data) and A2DP(audio) profiles on the same module.

How will I be able to switch so as to transmit Serial data (temperature) via BLE continuously and as soon as I try to transmit audio it is switched to BT classic, transmits the audio and is switched back to BLE again to transmit the temperature. 

I am new to this so having a few confusions.

Thanks,

Gaurav

  • Hi,

    SPPLE and audio are are different links(please see the Bluetooth specifications for more detail.).

    Mind that MSP430F5529 has only 128KB of flash, which might not be sufficient for running two profiles.

     

  • Hey Sundeep,

    Thanks for your prompt reply.

    Yes, I got your point. Both are two different profiles i.e SPP(LE or classic mode) and A2DP. Now since CC2564B-EVM is a dual mode module, will I be able to implement both the profiles simultaneously switching over from one to another as mentioned earlier, maybe on an interrupt basis. And if MSP430F5529 with 128kb flash won't support both the profiles, I can switch to a higher end controller, but first I should be aware of the ground rules i.e is that a possible option. If possible, then atleast can you pour me a few initial steps so that I can get an overall idea.

    Thanks,

    Gaurav..
