LAUNCHXL-CC26X2R1: rtls_example_with_rtls_util.py raise error "=== ERROR: No one of the nodes identified as RTLS MASTER ==="

Part Number: LAUNCHXL-CC26X2R1


I also try to control a RTLS_Master (Example Project from SimpleLink SDK 5_10_00_48) - on a LaunchPad CC2642R1 / CC2652R1 with BOOSTER - via the rtls_example_with_rtls_util.py.

As already mentioned in other forum entries and the documentation, I adapt the COM-Port for the master device.

If I run the Visual example the LaunchPad is identified as "Master" and everything works fine.

But if I execute the connection via IDE (Spyder) or Command Line, the master board is not identified.

Unfortunately, the created Log-File gives no further Information.

Do you have any idea why your "out of the box" example is not working?


  • Hi Sebastian,

    Make sure no other program running on the computer attempt to access the COM port used by the board (COM4 in your case).

    Make sure the python scripts and the embedded code come from the same SDK version. If not already done, review the README file in the rtls_agent folder and make sure to update all the python packets required.

    If none of the previous help, please check if you manage to use the serial COM port using PySerial.

    Keep us updated,
