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 address of the device with the matching NI string.
The address selected (either 16-bit short address or 64-bit extended address) is chosen based
on the destination device's MY command configuration.
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 local AT Command API frame:
1. The receiving device returns the 16-bit network and 64-bit extended addresses in an API
Command Response frame.
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. In the case of
an ERROR, the device does not exit command mode. Set the radius of the DN command using
the BH command.
When DN is sent as a local AT Command frame - 0x08:
1. The receiving device returns a success response in a AT Command Response frame - 0x88.
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.
