Modes
Transmit mode
When DigiMesh data is transmitted from one node to another, the destination node transmits a
network-level acknowledgment back across the established route to the source node. This
acknowledgment packet indicates to the source node that the destination node received the data
packet. If the source node does not receive a network acknowledgment, it retransmits the data.

Command mode
Command mode is a state in which the firmware interprets incoming characters as commands. It
allows you to modify the device's configuration using parameters you can set using AT
commands. When you want to read or set any parameter of the XTC RF Module using this mode, you
have to send an AT command. Every AT command starts with the letters AT followed by the two
characters that identify the command and then by some optional configuration values.
The operating modes of the XTC RF Module are controlled by the
but Command mode is always available as a mode the device can enter while configured for any of the
operating modes.
Command mode is available on the UART interface for all operating modes. You cannot use the SPI
interface to enter Command mode.
Enter Command mode
To get a device to switch into Command mode, you must issue the following sequence: +++ within one
second. There must be at least one second preceding and following the +++ sequence. Both the
command character (CC) and the silence before and after the sequence (GT) are configurable. When
the entrance criteria are met the device responds with OK\r on UART signifying that it has entered
Command mode successfully and is ready to start processing AT commands.
