Other Parts Discussed in Thread: CC2564

Hi all,

       I want to know about the maximum achievable data transfer rate using CC2564. Can anyone please tell me how much data rate we can achieve practically.

thanks

    Hi Kumar,

    The throughput will depend on the host and profile. For instance, the SPP throughput is higher with a TM4C MCU than a MSP430 MCU.

    Some benchmark numbers for SPP profile running on a MSP430 MCU are in the link below.

    Hi,
    Thanks a lot for your reply.
    As per the document referred by you, max data rate can be up to 670kbps approx in either ways. But my doubt is this data rate can be achieved practically or its just theoretical value. I am newbie working on classic bluetooth. I have to start working on a project with two profiles running simultaneously related to headset profile and profile which supports file transfer at higher rate. My host is going to be TM4C MCU and data will be transmitted to and from mobile phone(android application). Although i do not agree with but one of my friend has told me that bluetooth stack has not been designed yet for MCU for file transfer greater than around 20kbps(stack from other vendor). Throughput around 300kbps is also enough for me if i can achieve it.
    thanks

    Hi Kumar,

    The numbers shown in the wiki were obtained from actual measurements between two MSP430 + CC256x setups. Couple of points below:

    1) The numbers may vary if using a different peer device, i.e. BT dongle, BT phone, etc

    2) The tests were performed without any other user tasks running in the MSP430. The data was sent from an internal buffer. On the receiver side, the data was received and put into a buffer.

    Hi Miguel,
    Thanks for this useful information. I will do some test on this once i get the evaluation kit.
