[Common BLE] Filter to connect ?

[MainOFF]

Hi. I have a central device call C_Board. It is scanning to find device has name is "123456" . This meaning is any device has name "123456" can connect to C_Board. Have any solution to choose device to connect? Thank for help.

i have a function for this :

static bool is_valid_address(ble_gap_evt_adv_report_t const * p_adv_report)

{

if(p_adv_report->peer_addr.addr[0] == periph_addresses[0][0])
{//matches first byte of address 0
    if((p_adv_report->peer_addr.addr[1] == periph_addresses[0][1]) &&
       (p_adv_report->peer_addr.addr[2] == periph_addresses[0][2]) &&
       (p_adv_report->peer_addr.addr[3] == periph_addresses[0][3]) &&
       (p_adv_report->peer_addr.addr[4] == periph_addresses[0][4]) &&
       (p_adv_report->peer_addr.addr[5] == periph_addresses[0][5]))
    {
        return true;
    }
    else
    {
        return false;
    }
}
else if (p_adv_report->peer_addr.addr[0] == periph_addresses[1][0])
{//matches first byte of address 1
    if((p_adv_report->peer_addr.addr[1] == periph_addresses[1][1]) &&
       (p_adv_report->peer_addr.addr[2] == periph_addresses[1][2]) &&
       (p_adv_report->peer_addr.addr[3] == periph_addresses[1][3]) &&
       (p_adv_report->peer_addr.addr[4] == periph_addresses[1][4]) &&
       (p_adv_report->peer_addr.addr[5] == periph_addresses[1][5]))
    {
        return true;
    }
    else
    {
        return false;
    }
}
else
{
    return false;
}

}

And on the top , you declare your address board you want to connect :

static uint8_t                  periph_addresses[2][6] = {{0x76,0x4a,0x55,0x10,0x40,0xe5},{0xb6,0x70,0x30,0xba,0xbb,0xdd}};

Thanks for your help! I am going to test your code immediately. ( Can you say Vietnamese ?)

and how can I get address of board which I want to connect?
