Part Number: CC1310
Other Parts Discussed in Thread: CC1312R, CC1312R7

Our product failed to pass japanese TELEC certification in the carrier sense case.  The certification regulate that device should have the ability to sense the jamming sigal(carrier wave) in specific frequency and stop radio transmission.  The following picture is the regulation of carrier sense case.

My CC1310 software  is base on SDK example Ti 15.4-stack coprocessor. How could i implement this feature?  Is there any examples or projects for reference?

    Hi, you are correct that there are specific requirements around carrier sense to meet Japanese ARIB requirements. We have implemented support for this in the newest SDK (v6.10) for CC1311R, CC1312R, CC1312R7 devices, see release notes: https://dev.ti.com/tirex/explore/node?node=ABtW7La1LY-rjF6oV5OdyQ__BSEc4rl__LATEST 

    Since there was extensive development and test effort required, we currently do not have plans to backport this to the CC1310 release, Note that all the CC131x devices mentionnend above can be pin compatible with CC1310 in the 7x7 package.

    The other option you have is to implement a proprietary RF protocol based on the prop RF examples in the CC1310 SDK. We have customers who have done this successfully.
