dwm_node_id_get

Gets the full UWB address of the node. The address/ID is a unique 64-bit number. It is derived from the fixed prefix 0xDECA, the MCU unique Chip ID, and the DW1000 unique Part ID in following format: 0xDECA + 28 bits MCU unique Chip ID + 20 bits DW1000 unique Part ID.

void dwm_node_id_get(uint64_t *node_id)

Parameters

input – (none)
output – Status code, node_id
node_id – ? 64-bit integer ? (UWB node address/ID)

C code example

uint64_t node_id;
dwm_node_id_get(&node_id);
printf("node ID = 0x%llx \n", node_id);

SPI/UART example

TLV Request
Type	Length
0x30	0x00

Type 0x30 means command dwm_node_id_get

TLV Response
Type	Length	Value (see error codes)	Type	Length	Value
0x40	0x01	0x00	0x4E	0x08	8 bytes in little endian
