CC1310: Use OOK, Manchester Encoding,on the CC1310

Tan Sun
Intellectual 1810 points
Part Number: CC1310

We will design a sensor system, to connect many kind of sensor which from different vendor, it need set RF work under different mode.

It include:

1, 433M and 315M;

2, modulation :OOK and FSK;

3,code: Manchester Encoding, NRZ, BI-PHASE;

From TRM, can't find all register description about these setting.

Question are:

1, How to set working on 315M?

2,How to set  Manchester Encoding under FSK/OOK?

3, How to set  NRZ, BI-PHASE Encoding under  FSK/OOK?

Many thanks!

    Hi,

    Use SmartRF Studio and start with the 433 Mhz settings. If you don't get a link at 315 Mhz, I don't know if we can make it work.

    Please find some information in the proprietary rf users guide. But I don't think that manchester encoding/decoding is supported in OOK. If not, you would have to do it manually on the main core.

    Most probably you would have to implement that on the main core as well. Manually packet processing means: you set a sync word and a maximum packet length and disable variable length.

    If one of your protocols is not using a proper sync word, you will either get low performance or it will not work at all on the CC1310. That is especially the case with old protocols which just use a 0101010101... preamble followed by a single bit to mark the packet start. These protocols will NOT work on the CC1310. Although it is possible to hack something, I strongly discourage you from creating a product out of that.

    Please note that it is also not possible to receive FSK/OOK at the same time. You would need to switch the entire PHY configuration for that.

    Hi Richard,

    Thanks for your response.

    I know those are too many work mode to be compatible. But I don't want them work at same time. Just one mode in one time.

    So if they too complex to archive in one step, we can split them to simple, just like:

    1, If any sample code about OOK mode?

    2,  Manchester Encoding section in TRM is not clearly enough, can I find any sample code for Manchester Encoding with FSK? If "Others: Reserved" means more possible coding mode be supported by CC1310?

    The PER test in the SDK uses OOK:

    For Mancehster encoding you should look at hte link Richard posted and not the TRM. There are additional info in this post:
