请问如何修改MAC地址

//设置本地蓝牙MAC地址
uint32_t sd_ble_gap_address_set(ble_gap_addr_tconst*constp_addr);   用这个函数试试

void ble_address_change(void)
{
ble_gap_addr_t ble_addr;
sd_ble_gap_address_get(&ble_addr);
ble_addr.addr[0] = 0x99;
ble_addr.addr[1] = 0x99;
ble_addr.addr[2] = 0x99;
ble_addr.addr[3] = 0x99;
ble_addr.addr[4] = 0x99;
ble_addr.addr[5] = 0xff;


sd_ble_gap_address_set(BLE_GAP_ADDR_CYCLE_MODE_NONE,&ble_addr);
}
