Thank you for your reply I use the same code but i won't get mac id it shows only 000000

_u8 macAddressVal[SL_MAC_ADDR_LEN];
_u8 macAddressLen = SL_MAC_ADDR_LEN;
sl_NetCfgGet(SL_MAC_ADDRESS_GET,NULL,&macAddressLen,(_u8 *)macAddressVal);

UART_PRINT("\n\rMAC Address: %02x:%02x:%02x:%02x:%02x:%02x\n\r\n\r",
macAddressVal[0], macAddressVal[1], macAddressVal[2], macAddressVal[3], macAddressVal[4], macAddressVal[5]);
