When my central receives a scan from the client, it has the client's address in a CYBLE_GAPC_ADV_REPORT_T data structure.  My central can connect to the client using this address.  But in my client code, I get (I assume) my client's address by calling CyBle_GetDeviceAddress.  THese two addressed don't match, why?

If routine CyBle_GetDeviceAddress() is called while the client is advertising, the address returned matches what is in the advertising packet received by the Central.

Hello,

Could you please let me know how you configured your client device whether it is GAP peripheral or central.

Can you please share your project ?

Thanks,

P Yugandhar.

Thanks for your reply.  I have two CY8CKIT-042-BLE kits.  I also have two projects, one is a client and one as central.

The Client configuration:

     Profile:Custom

     Profile role: Server (GATT Server)

     GAP role: Periferal

The Central configuration:

     Profile:Custom

     Profile role:Client(GATT Client)

     GAP role: Central

My central is able to connect to the client and read/write data from/to the client.  Everything works.  My question is a curiosity question.  When I call  routine CyBle_GetDeviceAddress() on the client, I get a different address than advReport->peerBdAddr my Central receives in the following code snippet in the callback routine when receiving a scan result.

case CYBLE_EVT_GAPC_SCAN_PROGRESS_RESULT:

     advReport = (CYBLE_GAPC_ADV_REPORT_T *) eventParam;

The advReport->peerBdAddr address is what my central uses to connect to the client.

Again, everything works but I don't understand why the address obtained by call CyBle_GetDeviceAddress() on the client is not the address obtained by the Central from the scan.

I don't think sharing my projects would add any more useful information.

Note: BLE device with GATT role as server and GAP role as Peripheral is a Peripheral device with server configuration.

Thanks,
