    PSOC 4100 BLE device address


      For the public mac address used for bluetooth we have used the "silicon generated" numbers generated from the Wafer ID and X-Y die

      as explained in Setting Bluetooth Device Address – KBA211407


      is the numbers in this situation unique?


      if not could we have situations with several devices with the same address?


      we use PSOC 4100 BLE

          When the 'silicon generated' box is checked. This will make a unique address for each device which can have a maximum combination of 2^24 device address. This generation of address is automatically taken care inside the BLE Stack.

          Note: The silicon-generated “Company assigned” option does not guarantee a unique device address. For mass production, Cypress strongly recommends that the device address be programmed into the user’s SFLASH location (row 0 of user SFLASH) via the SWD interface. For more information, please refer to page44 in BLE Component datasheet v3.63.
