RE: Mesh with customize MAC address ??

Hi Guorong,

Could you give more information about what you want to achieve ? Do you want to change the new MAC address for mesh packet or you want to change the MAC address for PB-GATT or PROXY packet ?
Note that calling sd_ble_gap_addr_set () only change the MAC address for BLE PB-GATT or PROXY packet, not the mesh advertising packet.
I did a quick test here with calling sd_ble_gap_addr_set(), before start() and it worked fine for me:

int main(void)
{
    initialize();
    ble_gap_addr_t       m_my_addr;                                                              /**< Local GAP address. */

  m_my_addr.addr[5]   = 0xC0;
  m_my_addr.addr[4]   = 0xEE;
  m_my_addr.addr[3]   = 0xDD;
  m_my_addr.addr[2]   = 0xCC;
  m_my_addr.addr[1]   = 0xBB;
  m_my_addr.addr[0]   = 0xCA;
  m_my_addr.addr_type=BLE_GAP_ADDR_TYPE_RANDOM_STATIC;
  uint8_t  err_code = sd_ble_gap_addr_set(&m_my_addr);
  APP_ERROR_CHECK(err_code);
    start();
  

    for (;;)
    {
        (void)sd_app_evt_wait();
    }
}
