LAUNCHXL-CC26X2R1: LAUNCHXL-CC26X2R1, BOOSTXL-AoA pairing with smartphone

Part Number: LAUNCHXL-CC26X2R1
Other Parts Discussed in Thread: SYSCONFIG

Hello,

I am working on RTLS with launchpad CC26XR1 and boostxl-AoA. these boards are loaded with rtls project files: Master, Slave and Passive

After building the projects and flashing the launchpads. I executed rtls_ui using the computer. my questions are

1. Is it possible to pair these devices with smartphone?

2. Is it necessary that smartphone should have version bluetooth 5.1 to support the AoA algorithm?

3. RTLS_UI error when placing the boostxl-AoA vertically while the launchpad is placed in horizontal surface?

It would be great if the questions are answered asap

Thank you

Best regards

Prathap

    Hi,

    1- Yes it is possible to pair the rtls_slave device with a phone. The rtls_master has a central role so you will probably have some troubles to pair your phone with it (phones are generally only working as central). The rtls_passive cannot be paired because the rtls_passive does not use a full BLE stack but a micro-BLEStack (please review the BLEStack User's guide for more details.

    2- The phone needs to have the ability to send or receive a CTE, if not no AOA calculation is possible.

    3- This should not happen.

    I hope this will help,

    Regards,

    Hi.

    Thank you very much for your reply

    I would like to pair RTLS_master to smartphone and also generate a passkey

    which line should I edit for pairing and security?

    Lets say, If I have the smartphone that supports 5,1 direction finding. RTLS_Passive collects the I/Q sample with micro BLE stack?

    Best regards,

    Prathap

    Hi,

    Regarding the pairing question, please consult the SimpleLink Academy.

    As you mentioned, passive RTLS devices use the Micro BLE Stack.

    Hi,

    I tried the pairing and security tasks with project zero, it works fine

    But, with rtls_master project I tried removing the custom stack from rtls_master.syscfg, as it does not support multiple stack and I get the following errors:

    Please advice

    Best regards

    Hi,

    If you remove the "Custom" stack from SysConfig, AOA won't be available anymore. Please do not modify this in SysConfig.

    Instead, review the application files (especially rtls_slave.c). You will see that all the code required for pairing / bonding is already available. Modify this code directly to fit your requirements.

    Kind regards,
