Obtaining the identity of connected party in BLE cc2541

Other Parts Discussed in Thread: CC2541, CC2640

I have an application where I am designing a device based on Simple Peripheral Profile.

I need to implement a pairing mechanism in which I can add and remove parties to authorized users list.

Is there an available mechanism for this?

If not how do I get connected parties identity info so I can save it in flash?

Thanks,

    Hi Ozgur,

    I suggest looking at the GAP Bond Manager. Although you are using CC2541, there is a good explanation in the CC2640 BLE SW Developer's Guide (SWRU393). The description applies to CC254x.

    Best wishes

    Thanks for the reply.

    I was using

    "

    // get the connected parties id
              GAPRole_GetParameter(GAPROLE_CONN_BD_ADDR, connected_party);

    "

     

    to get the address of connected device, but I noticed everytime I reset my Iphone, it changes this address. I need to be able to remember the device, how do I get something like a MAC# that is permanently belong to the device I am connected to?

     

    Thanks,

    Hi Ozgur,

    The iOS device (and now Android 5.x) are using Random Addresses. See this link: smartstoreprivacy.org/.../about-mobile-location-analytics-technology

    If you are bonding, then the iOS will only then share it's public BD_ADDR. You cannot use the Auto Sync to Whilelist feature with these devices as they will re-connect with a Private Resolvable Address.

    Please search the forum for "iOS Whitelist" for more details.

    Best wishes
