public static ble address

[energy]

Hi,

We bought a mac bd addr pool from IEEE Where is the best way to store this mac adress during production ? We guess the type will be: BLE_GAP_ADDR_TYPE_PUBLIC

Do you have example for the init with public adress ? Is there any drawback of using static public address except security ?

Thanks

Hi energy,

You can store the address anywhere in the flash or in UICR region (there are CUSTOMER[xx] bytes available). However you will need to set the address manually through sd_ble_gap_adddress_set call (if you use Nordic Soft Device) e.g. like this:

// Local variables
uint32_t       err_code;
ble_gap_addr_t ble_gap_addr;

// ...

ble_gap_addr.addr_type = BLE_GAP_ADDR_TYPE_PUBLIC;
memcpy((uint8_t *)ble_gap_addr.addr, (uint8_t *)(NRF_UICR + 0x0080), BLE_GAP_ADDR_LEN);
err_code = sd_ble_gap_address_set(BLE_GAP_ADDR_CYCLE_MODE_NONE, &ble_gap_addr);
APP_ERROR_CHECK(err_code);

I don't see any problem in using Public static address except privacy concerns. Cheers Jan
