LAUNCHXL-CC26X2R1: Merge of RTLS master and passive

Part Number: LAUNCHXL-CC26X2R1


Hello,

The RTLS toolbox for CC26x2 (SDK 3.20) describes a setup of 3 launchpads: master, slave, and passive. The forum post [1] explains the necessity of separating master and passive due to limited resources. Is this still true for CC26X2? Is there an example of merged master and passive roles?

Thanks,

Igor

    Hi Igor,

    EDIT: Allow me to correct myself. We intend to not have this limitation in the Q3 SDK  (SDK 3.30) for CC26x2. In the SDK 3.30 the RTLS toolbox for CC26x2 will enable the master to take the IQ data per the BLE 5.1 specification.

    At this point, the passive is needed to do AoA and take IQ data. In the next SDK, the passive will not be needed for the CC2642 but can be valuable in certain use cases for things like car access. The passive application is actually a connection following application and requires the master and the slave to be connected to work.

    For you, you can start evaluation of AoA with the passive following a connection between master and slave where the slave device is transmitting the CTE. In the future, you will be able to use just master and slave and take IQ data with the master.
