This command applies to the XBee/XBee-PRO S2C DigiMesh 2.4.
Discovers and reports all devices found within immediate (1 hop) RF range. FN reports the following information for each device it discovers:
MY<CR> (always 0xFFFE)
SH<CR>
SL<CR>
NI<CR> (Variable length)
PARENT_NETWORK ADDRESS<CR> (2 bytes) (always 0xFFFE)
DEVICE_TYPE<CR> (1 byte: 0 = Coordinator, 1 = Router, 2 = End Device)
STATUS<CR> (1 byte: reserved)
PROFILE_ID<CR> (2 bytes)
MANUFACTURER_ID<CR> (2 bytes)
DIGI DEVICE TYPE<CR> (4 bytes. Optionally included based on NO (Network Discovery Options) settings.)
RSSI OF LAST HOP<CR> (1 byte. Optionally included based on NO (Network Discovery Options) settings.)
<CR>
If you send the FN command through a local AT Command (0x08) API frame, each response returns as a separate AT Command Response (0x88) or Remote Command Response (0x97) frame, respectively. The data consists of the bytes in the previous list without the carriage return delimiters. The NI string ends in a 0x00 null character.
FN accepts a NI (Node Identifier) as an argument.
See The FN (Find Neighbors) command for more details.
