dwm_mac_addr_set
Sets the MAC address of the BLE, UWB, Ethernet or Wi-Fi interface and needs reset to take effect. It Should not be used frequently since it writes the internal non-volatile memory. Factory reset is needed (dwm_factory_reset) to use the default MAC address. The two least significant bytes of the UWB MAC address must not be equal to 0x0000 or 0xFFFF. The BLE address can be either the Random or the Public BLE address. The Ethernet and the Wi-Fi address must respect the EUI-48 format, and the U/I bits must be set accordingly.
-
void dwm_mac_addr_set(dwm_mac_addr_t *addr)
- Parameters
input – addr_type, addr_value
addr_type – ? 8-bit integer ? (0=UWB address, 1=BLE Random address, 2=BLE Public address, 3=ETH address, 4= WIFI address, ETH and WIFI is supported only on the gateway)
addr_value – ? 6 bytes ? (6 byte long MAC address)
output: – err_code
C code example
dwm_mac_addr_t addr;
addr.type: NODE_ADDR_TYPE_UWB;
addr.bytes[0]: 0xAA;
addr.bytes[1]: 0xBB;
addr.bytes[2]: 0xCC;
addr.bytes[3]: 0xDD;
addr.bytes[4]: 0xEE;
addr.bytes[5]: 0xFF;
int rv: dwm_mac_addr_set(&addr);
if (rv != DWM_OK) {
printf("can't set node address, error %d\n", rv);
}
