◆ deployment_id_from_iid()

uint16_t deployment_id_from_iid ( const uip_ipaddr_t * ipaddr )

Get node ID from the IID of an IPv6 address.

Parameters

ipaddr The IPv6 (global or link-local) address that contains the IID

Returns: Node ID from a corresponding IID

◆ deployment_id_from_index()

uint16_t deployment_id_from_index ( uint16_t index )

Get node ID from index in mapping table.

Parameters

index The index in the deployment mapping table

Returns: Node ID at the corresponding index

◆ deployment_id_from_lladdr()

uint16_t deployment_id_from_lladdr ( const linkaddr_t * lladdr )

Get node ID from a link-layer address, from the deployment mapping table.

Parameters

lladdr The link-layer address to look up for

Returns: Node ID from a corresponding link-layer address

◆ deployment_init()

void deployment_init ( void )

DEPLOYMENT_MAPPING: A table of struct id_mac that provides ID-MAC mapping for a deployment.

Example with four nodes: In configuration file: #define DEPLOYMENT_MAPPING custom_array In a .c file: const struct id_mac custom_array[] = { { 1, {{0x00,0x12,0x4b,0x00,0x06,0x0d,0xb6,0x14}}}, { 2, {{0x00,0x12,0x4b,0x00,0x06,0x0d,0xb1,0xe7}}}, { 3, {{0x00,0x12,0x4b,0x00,0x06,0x0d,0xb4,0x35}}}, { 4, {{0x00,0x12,0x4b,0x00,0x06,0x0d,0xb1,0xcf}}}, { 0, {{0}}} }; Initialize the deployment module
