DN (Discover Node)

This command applies to the XBee 3 DigiMesh RF Module.

Resolves an NI (Node identifier) string to a physical address (case sensitive).

The DN command cannot be issued from within MicroPython or over BLE.

The following events occur after DN discovers the destination node:

When DN is sent in Command mode:

  1. The requesting node sets DL and DH to the address of the device with the matching NI string.
  2. The requesting node returns OK (or ERROR).
  3. If the requesting node returns OK (node found), it exits Command mode immediately with DH/DL set to the node that is found so that the next serial input is sent to the node designated by the DN parameter.

  4. If the requesting node returns ERROR, (node not found), it remains in Command mode, allowing you to enter further commands.

When DN is sent as a local Local AT Command Request - 0x08:

  1. The requesting node returns 0xFFFE followed by its 64-bit extended addresses in an Local AT Command Response - 0x88.
  2. If there is no response from a module within (N?* 100) milliseconds or you do not specify a parameter (by leaving it blank), the requesting node returns an ERROR message.
