n
The receiving node establishes a DigiMesh route back to the originating node, if there is space
in the routing table.
n
The
DH
and
DL
of the receiving node update to the address of the originating node if the
AG
parameter matches the current
DH
/
DL
of the receiving node.
n
API-enabled devices with updated
DH
and
DL
send an Aggregate Addressing Update frame
(0x8E) out the serial port.
Note
The
AG
command is only available on products that support DigiMesh.
Parameter range
Any 64-bit address
Default
N/A
DN (Discover Node)
Resolves an
NI
(Node identifier) string to a physical address (case sensitive).
The following events occur after
DN
discovers the destination node:
When
DN
is sent in Command mode:
1. The device sets
DL
and
DH
to the extended (64-bit) address of the device with the matching
NI
string.
2. The receiving device returns OK (or ERROR).
3. The device exits Command mode to allow for immediate communication. If an ERROR is
received, then Command mode does not exit.
When
DN
is sent as a
:
1. The receiving device returns 0xFFFE followed by its 64-bit extended addresses in a
2. If there is no response from a module within (
NT
* 100) milliseconds or you do not specify a
parameter (by leaving it blank), the receiving device returns an ERROR message.
Parameter range
20-byte ASCII string
Default
N/A
ND (Network Discover)
Discovers and reports all of the devices it finds on a network. If you send
ND
through a local API frame,
each network node returns a separate AT Command Response (0x88) or Remote Command Response
(0x97) frame, respectively.
Parameter range
N/A
