Sending Control Data Using CC8530

Other Parts Discussed in Thread: CC8530

Hey there,

I'm thinking of using CC8530 for my senior design class. The project I'm working on required audio and data to be send via Bluetooth(wireless). From the description page, CC8530 is promoted to be able to send and receive 4 audio channels which fits perfectly. However, I could not find anywhere in the data sheet if CC8530 is also able to send and receive 16 bits of data. 

If the CC8530 can in fact send and receive data, is there any maximum number of bits of data it can transfer?

Thanks

    Hi,

    The maximal number of bits transmitted over the air per sample is 16 bits. We have, on the other hand,  a format called PCME24 thatsupport 24 bit dynamic range but still only 16 bit transmitted.

    Some info about PCME24 from the User's guide:

    The PCME24 format interleaves the incoming 24-bit samples, as done by the PCM16 format, and then
    converts four and four 24-bit samples into micro-blocks of four 15-bit sample values and a common 4-bit shift value, thereby using the same data bandwidth as PCM16. By shifting the 15-bit window within the 24-bit sample space according to the highest sample value in each 4-sample block, the format achieves 15-bit signal-to-noise ratio and 24-bit dynamic range. With identical data bandwidth and transport mechanism, the PCME24 format offers link robustness identical to that of the PCM16 streaming format.


    Best regards,
    Johan
