3.3. 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'. Hexadec-
imal 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
AT Command: AT%V
Binary Command: 0x3B (59 decimal)
Parameter Range (read-only):
0x2CCCA - 0x5BFFA
(2.80 - 5.75 decimal)
Number of bytes returned: 4
AT Command: ATAM
Binary Command: 0x40 (64 decimal)
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 Command: ATAP
Parameter Range: 0 - 2
Parameter

Default Parameter Value:0
Number of Bytes Returned:1
Minimum Firmware Version Required: 2.x20
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 inadvert-
ent entrance into AT Command Mode.
AT Command: ATAT
Binary Command: 0x05 (5 decimal)
Parameter Range: 2 - (ATST-3), up to 0x7FFC
[x 100 milliseconds]
Default Parameter Value: 0x0A (10 decimal)
Number of bytes returned: 2
Related Commands: BT (Guard Time Before),
CC (Command Sequence Character)
Refer to the ‘AT Command Mode’ section [p17] for
more information regarding the AT Command Mode Sequence.
