BlueNRG unique IEEE board addresses?

Hello - I have run 4 different boards, X-NUCLEO-IDB04A1, from the debugger, stopping on a break point right after a call to hci_read_bd_addr() (which returns success), and all 4 boards had this same board address:

04:02:EC:25:00:FD In order to go into commercial production with a BTLE product, is it required to ensure unique board addresses? In other words, is it required to buy a block of addresses and ensure that each board produced uses exactly one of the block bought? Thanks, #ble-ieee-board-address

Hi,

A BLE Devices are identified using a public device address or a random device address.  Where the public device address shall be created in accordance with section 9.2 (''48-

bit universal LAN MAC addresses'') of the IEEE 802-2001 standard (

http://standards.ieee.org/getieee802/download/802-2001.pdf

) and using a valid Organizationally Unique Identifier (OUI) obtained from the IEEE Registration Authority (see

http://standards.ieee.org/regauth/oui/forms/

and sections 9 and 9.1 of the IEEE 802-2001 specification). Otherwise, you can use a random device address.

Thank you for the response. After digging in the spec a little more, searching for random address, I read and understand the option to use a randomly generated static address that meets the spec.

Hi ,

            Please tell me the procedure to generate Static Random address for BlueNRG. Because i also tried to read board address, but all the board gives same address.

Dear Customer,

Using the BlueNRG, you can:

- use the static random access genereted after each reset - set a specific static Random address using the command HCI_LE_SET_RANDOM_ADDRESS (therefore you know the address!!)

Anyway, there is not the capability to read the random address.

Instead using the BlueNRG-MS, the static random address is stored inside the Flash. The address is loaded when doing ACI_GAP_INIT. Hence, to overwrite the static random address the HCI_LE_SET_RANDOM_ADDRESS must be called after ACI_GAP_INIT.

To read the random address, you have to use the command:

ACI_HAL_READ_CONFIG_DATA (Offset=0x80).

To do this,  It nedded to download the latest version of GUI DK.
