This command applies to the XBee/XBee-PRO S2C DigiMesh 2.4.
The command reports the following information after a jittered time delay:
SH<CR> (4 bytes)
SL<CR> (4 bytes)
DB<CR> (Contains the detected signal strength of the response in negative dBm units)
NI <CR> (variable, 0-20 bytes plus 0x00 character)
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 settings.)
RSSI OF LAST HOP<CR> (1 byte. Optionally included based on NO settings.)
<CR>
If you send FN (Find Neighbors) in Command mode, after (NT*100) ms + overhead time, the command ends by returning a carriage return, represented by <CR>.
ND accepts an NI (Node Identifier) as an argument. For more details, see Directed node discovery.
Broadcast an ND command to the network. If the command includes an optional node identifier string parameter, only those devices with a matching NI string respond without a random offset delay. If the command does not include a node identifier string parameter, all devices respond with a random offset delay.
The NT (Network Discovery Back-off) setting determines the range of the random offset delay. The NO (Network Discovery Options) setting sets options for the Node Discovery. For more information about options that affect the behavior of the ND command, see the description of NO.
WARNING! If the NT setting is small relative to the number of devices on the network, responses may be lost due to channel congestion. Regardless of the NT setting, because the random offset only mitigates transmission collisions, getting responses from all devices in the network is not guaranteed.
