Command Descriptions
Commands in this section are listed alphabetically. Command categories are designated between
the "< >" symbols that follow each command title. By default, XTend RF Modules expect numerical
values in hexadecimal since the default value of the CF (Number Base) Parameter is '1'.
Hexadecimal values are designated by the "0x" prefix and decimal values by the "d" suffix.
%V (Board Voltage) Command
<Diagnostics> %V Command is used to read the
current voltage of the module circuit board.
Sample Output:
5.02 V (when ATCF = 0)
5051F (when ATCF = 1) *
5.02 (when ATCF = 2)
* When CF = 1 (default), a hex integer is shown
that is equal to (voltage * 65536d).
AM (Auto-set MY) Command
<Networking & Security> AM Command is used
to automatically set the MY (Source Address)
parameter from the factory-set serial number of
the module. The address is formed with bits 29,
28 and 13-0 of the serial number (in that order).
The resulting value is displayed as a result of this command.
AP (API Enable) Command
<Serial Interfacing> The AP command is used to
enable the module to operate using the frame-
based API operation.
AT (Guard Time After) Command
<Command Mode Options> AT Command is used
to set/read the time-of-silence that follows the
command sequence character (CC Command) of
the AT Command Mode Sequence (BT + CC +
AT). By default, 1 second must elapse before and
after the command sequence character.
The times-of-silence surrounding the command
sequence character are used to prevent
inadvertent entrance into AT Command Mode.
Refer to the ‘AT Command Mode’ section [p18] for
more information regarding the AT Command Mode Sequence.
