XBee‐PRO® 900 OEM RF Modules
Node Identification Commands
AT
Name and Description
Command
Node Discover - Node Discover. Discovers and reports all RF modules found. The
following information is reported for each module discovered.
MY<CR>
SH<CR>
SL<CR>
NI<CR> (Variable length)
PARENT_NETWORK ADDRESS (2 Bytes)<CR>
DEVICE_TYPE<CR> (1 Byte: 0=Coord, 1=Router, 2=End Device)
STATUS<CR> (1 Byte: Reserved)
ND
PROFILE_ID<CR> (2 Bytes)
MANUFACTURER_ID<CR> (2 Bytes)
<CR>
After (NT * 100) milliseconds, the command ends by returning a <CR>. ND also accepts
a Node Identifier (NI) as a parameter (optional). In this case, only a module that
matches the supplied identifier will respond. If ND is sent through the API, each
response is returned as a separate AT_CMD_Response packet. The data consists of
the above listed bytes without the carriage return delimiters. The NI string will end in a
"0x00" null character.
Sleep Commands
AT
Name and Description
Command
SM Sleep Mode.
Sleep Options.
Options include:
SO
0 bit = Preferred sleep coordinator.
All other bits are reserved.
Wake Time
Units of msec, represented in hex.
Note: The minimum valid value for ST is a function of SP, NN, and NH.
ST
If the user attempts to set the value of ST too low, it will be increased automatically to
a minimum effective value.
Sleep Time
SP
Units of 10 milliseconds, represented in hex. The value of ST will be adjusted upwards
DigiMesh
Mesh Commands: Network Level Commands
AT
Name and Description
Command
Network Hops Set or read the maximum number of hops expected to be seen in a
NH network route. This value doesn't limit the number of hops allowed, but it is used to
calculate timeouts waiting for network acknowledgements.
Network Delay Slots Set or read the maximum random number of network delay slots
NN
before rebroadcasting a network packet. One network delay slot is approximately 13ms.
Network Route Requests Set or read the maximum number of route discovery retries
NQ
allowed to find a path to the destination node. If NQ is zero, RREQ will only be sent once.
Mesh Network Retries Set or read the maximum number of network packet delivery
MR attempts. If MR is non-zero, packets sent will request a network acknowledgement, and
can be resent up to NR+1 times if no acknowledgements are received.]
Security Commands
AT
Name and Description
Command
Security Enable Enables or disables 128-bit AES encryption. This command parameter
EE
should be set the same on all devices.
Security Key Sets the 16 byte - 128-bit network security key value. This command is
KY write-only. Attempts to read KY will return an OK status. This command parameter
should be set the same on all devices.
