LAUNCHXL-CC26X2R1: One Master - More Slave RTLS Solution

Abdurrahman Zeybey

Hello,

I have a setup that one master(BOOSTXL-AOA + LAUNCHXL-CC26X2R1) and two slave (2 x LAUNCHXL-CC26X2R1), try to get AoA measurement of both slave devices from master.

Actually the python code below indicates that it can connect both slave devices, but the AoA measurement payloads just come from one slave device.

Is it possible to get both of them?


print(f"Start scan for {scan_time_sec} sec")
scan_results = rtlsUtil.scan(scan_time_sec)
print(f"Scan Results: {scan_results}")

for scan_result in scan_results:
    try:
        print("Trying to Connect : " + scan_result['addr'])
        rtlsUtil.ble_connect(scan_result, connect_interval_mSec)
        print("Connection Success : " + scan_result['addr'])
        time.sleep(2)
    except:
        print("Error Connection : " + scan_result['addr'])

Trying to Connect : 80:6F:B0:EE:BD:67
Connection Success : 80:6F:B0:EE:BD:67
Trying to Connect : 80:6F:B0:EE:BB:AD
Connection Success : 80:6F:B0:EE:BB:AD

Hi,

As of today, the OOB embedded code does not support multiple slave connections. If you have a look at it you will see that there is only one connection handle available. As a result, when you ask the master to form the second connection, he basically erase the first connection.

There are two ways to achieve what you want:

- Modify the embedded code in order to support several slave connection. The example multi_role (stored in your SDK) can be a valuable source for you.

- Wait until the Q4 release: this configuration will then be supported

I hope this will help,

Best regards,

Hi Clément,

Would you happen to have an estimate on the Q4 release date? Is it likely to release this year or perhaps early January?

Thanks,

Max

Hi,

The date of the Q4 release has not been yet communicated. You can expect a release date for end of December - beginning of January.

Hi Clement,

I will try to modify master app with respect to multi_role example. Also I'm very excited to see one master-multiple slave and one slave-multiple master examples in the upcoming release. These are the important features to enable complete RTLS solution.

Kind reagards.
