CCS/CC2650: 5Mbps proprietary mode support (need to sign NDA?)

Teddy
Intellectual 850 points
Part Number: CC2650
Other Parts Discussed in Thread: CC1310, CC2640R2F, CC2640

Tool/software: Code Composer Studio

I checked the current SDK support of this cc2650 module (e.g. for cc2650 launchpad) for 5mbps support and do not find any. I'd like to confirm from you about this true?

On the other hand, I also look around in this fourm for the similar issue with cc2650 higher speed support and noted that NDA is required to sign for the 5mbps example or patch release. Is this also true?

Please advise me, and well appreciated for this as we are looking for a suitable module for 5mbps support.

Thank you so much.

    Hi Teddy,

    What is your use case for 5 Mbps?

    We can provide settings for this mode, but I would rather recommend you use 2 Mbps instead. This is because the 5 Mbps configuration has quite a significant overhead, the preamble is very long for example, so 2 Mbps is often a better alternative.

    Regards,

    Thanks for your reply.

    We need high throughput for image transfer at 2.4GHz, at least 4Mbps or more, and low power consumption. We've ever used cc1310 for the similar purpose at 915MHz but this time need 2.4GHz. We understand the necessary overhead for the 5Mbps throughput.

    I am appreciated if you can provide me the settings for 5Mbps support. We will start software development based on the cc2650 launchpad.

    As I cannot find the SDK for cc2650 launchpad on TI website, which software or examples should I use for 5Mbps testing if I get the settings, e.g. rfPacketErrorRate?


    Thanks

    Hi Teddy,

    I have attached 5 Mbps settings for CC2640R2F.

    Does the cc2650 share the same setting as cc2640r2f for the 5mbps support? We will use cc2650 as the hardware.

    Thanks

    Hi Teddy,

    You must use the CC2640R2F due to availability of SW. We are not able to support this on CC2650.

    We are still evaluating the cc2650 and cc2640r2f, and do not yet decide to use which one as development, how about if we really want the 5mbps support for cc2650 and what should we need to follow to do, e.g. contact our local TI FAE and sign NDA for the software setting, etc.? Thank you so much

    Hi Teddy,

    We do not offer the same level of SW support for CC2650 and there is no SW roadmap for the device. As such, I would highly recommend using the CC2640R2F.

    Thank you. I am clear now.

    I read the cc2640r2f datasheet and it does not have the rf relevant specification for the 5mbps. Instead, I found them from the cc2640 datasheet as below. Does the cc2640r2f share the same rf 5mbps specification as cc2640? and can I use the same 5mbps software settings of cc2640r2f that you provided me on the cc2640? Thanks.

    The 5 Mbps performance would be the same on CC2640R2F as on C2640.

    The SW settings I provided can only be used on the CC2640R2F, not the CC2640.

    OK, thanks. What is the maximum payload size that can be used for the 5mbps setting on cc2640r2f? I see a comment on the example rfPacketErrorRate from simplelink cc2640r2 sdk v2.40.00 that can be in maximum 4K byte but is hard-coded now to 254 byte. Is it right?

    Hi Fredrik,

    Can you provide 2Mbps configuration file by cc2640r2f proprietary mode for me?Thank you very much.
