CCS/LAUNCHXL-CC26X2R1: Multi_role connecting devices: Unknown Cmd Status: 0x2025::0x00

Part Number: LAUNCHXL-CC26X2R1

Tool/software: Code Composer Studio

Hello,

I am using LAUNCHXL-CC26X2R1 & my project is based on multi_role example.

SDK simplelink_cc13x2_26x2_sdk_3_40_00_02.

I am connecting 2 units: 1st one advertises, 2nd scans & connects to it.

I get some unknown commands in multi_role_processStackMsg():

I've looked for those commands in hci_tl.h:

#define HCI_LE_READ_LOCAL_P256_PUBLIC_KEY     0x2025

#define HCI_LE_GENERATE_DHKEY                             0x2026

#define HCI_LE_CONNECTION_UPDATE                      0x2013

But for some reason these commands doesn't show up in the TI BLE5-Stack API Documentation of the HCI Constants.

What are those commands? Is there anything I should do about it?

Thanks,

Amit

    Hi Amit, 

    What functionality have you added to the multi_role project? Did you see this kind of behavior using the unmodified multi_role project? 

    Thanks,

    Hey Elin,

    I get the same results on the base project of Multi-Role. This is a print that occurs when reaching a command type that doesn't have a case handling it on the function processStackMsg, and the base code of the Multi-Role project doesn't handle these commands as well.

    In order to resolve these unhandled commands, I need to know what they mean, however, as stated before, I cannot find those on the API reference. I will appreciate if you can elaborate what it means.

    It is important since I sometimes get a pairing error number 11 (which I believe that it stands for: SMP_PAIRING_FAILED_DHKEY_CHECK_FAILED)

    I suspect that these two issues are connected, but I don't have a way to make sure of that.

    Hi Amit, 

    Apologies for the delay and thank you for providing more details to your problem.

    Since you are experiencing the same issue using multi_role project straight from the SDK I will try and reproduce your issue using your setup. Are you using two CC26X2R1 LaunchPads? Are you using multi_role on both or does the second device use another project like simple_peripheral?

    Thanks, 
    Elin

    Hey Elin,

    Yes. I am using two CC26X2R1 LaunchPads, multi_role on both sides.

    Thanks,

    Amit

    Hi Amit, 

    Just tested and I don't see the issue you are describing.

    Thanks,
