🔬 Test setup

RTLS System

This RTLS System setup guide contains information from Ti developer hub containing information about the hardware setup and additional information for a working test environment.

From dev.ti.com

This page contains information about how to setup the AoA demo from Ti and which control commands are accepted by RTLS Control software.

Software Setup

For a working AoA example, there are three different roles which take care of the calculation and the function of AoA.

RTLS Master

• For RTLS Master and RTLS Slave projects, the configuration -DRTLS_LOCATIONING_AOA in build_config.opt file that is located in the project directory, controls the build.
• To build AoA, keep the option uncommented: -DRTLS_LOCATIONING_AOA
• Master role will not collect I/Q samples

RTLS Slave

• For RTLS Master and RTLS Slave projects, the configuration -DRTLS_LOCATIONING_AOA in build_config.opt file that is located in the project directory, controls the build.
• To build AoA, keep the option uncommented: -DRTLS_LOCATIONING_AOA
• Slave will send out a constant tone at the end of connection packet and it will not collect I/Q samples

RTLS Passive

• RTLS_LOCATIONING_AOA must be defined in predefined symbol/preprocessor symbol.
• Passive will collect I/Q samples
• When using AoA raw output mode (AOA_MODE_RAW), consider the following:
  • Connection interval of BLE must be at least 300ms to accomodate outputing all of the samples (a large 2k bytes chunk)
  • Large amounts of heap will be used to support this mode
