MAC Address
Each SimpleLink Wi-Fi device is manufactured with a unique MAC address. The user can overwrite this
default MAC address. The configuration is persistent with no dependency on the system-persistent
configuration. Setting a MAC address takes effect only after reset, and can be set by the Image Creator.
NOTE:
When configuring a new MAC address, the original MAC address is still used for Image
Creator development mode. For more information, refer to the
CC3120/CC3220 SimpleLink
Wi-Fi and Internet of Things Image Creator User's Guide
Example:
_i16 Status;
_u8 MAC_Address[6];
_i16 Role;
MAC_Address[0] = 0x8;
MAC_Address[1] = 0x0;
MAC_Address[2] = 0x28;
MAC_Address[3] = 0x22;
MAC_Address[4] = 0x69;
MAC_Address[5] = 0x31;
Status
= sl_NetCfgSet(SL_NETCFG_MAC_ADDRESS_SET,1,SL_MAC_ADDR_LEN,(_u8 *)MAC_Address);
if
( Status )
{
/* error */
}
Status = sl_Stop(0);
if
( Status )
{
/* error */
}
Role = sl_Start(NULL,NULL,NULL);
