ND (Network Discover)

This command applies to the XBee®-PRO 900HP RF Module.

Discovers and reports all devices found in the network. For each discovered device, the following information is returned:

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.)

After (NT * 100) milliseconds, the command ends by returning a <CR>. ND also accepts NI (Node Identifier) as a parameter (optional). In this case, only a device that matches the supplied identifier responds.

If you send ND through a local API frame, the device returns each response as a separate AT_CMD_Response packet. The data consists of the bytes listed above without the carriage return delimiters. The NI string ends in a 0x00 null character.
