Device address fro public device address format

[Jeffery]

Hi In current Desktop 2 project, We know that software device stack takes 48-bit random device address from FICR registers (DEVICEADDR[1: 0]) for BTLE. Each nRF51 has unigue address. We are planning to apply public device address (compny_assigned + company_id) from IEEE. How can we replace FICR device address by it in nRF51? Then, no side effect at all.

Hi I tried your method to change device address but it seems not working. The below is test code. Using debug mode and seting breakpoint in _NOP(), the pointer was never stopped.

//Set new device address to software stack ble_gap_addr_t same_addr; same_addr.addr[0] = 0x00; same_addr.addr[1] = 0x01; same_addr.addr[2] = 0x02; same_addr.addr[3] = 0x03; same_addr.addr[4] = 0x04; same_addr.addr[5] = 0x05;

sd_ble_gap_address_set(&same_addr);

//Then, get the device address from software stack. err_code = sd_ble_gap_address_get(&ble_addr);
ASSERT(err_code == NRF_SUCCESS);

if((ble_addr.addr[0] ==0)&&(ble_addr.addr[1] ==1)&&(ble_addr.addr[2] ==2)&&(ble_addr.addr[3] ==3)&&     (ble_addr.addr[4] ==4)&&(ble_addr.addr[5] ==5)){
         __NOP();    
}

Hi there,

You need to set same_addr.addr_type to a value, in your case it would probably be:

BLE_GAP_ADDR_TYPE_RANDOM_STATIC

Hope this helps,
