Command Descriptions
Commands in this section are listed alphabetically. Command categories are designated between
the “< >” symbols that follow each command title. By default, XTend 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
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
<Diagnostics> %V Command is used to read the
current voltage of the XTend 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 module serial
number. The address is formed with bits 29, 28 and 13-0 of the serial number (in that order).
The value is displayed as a result of this command.
AT Command: ATAM
Binary Command: 0x40 (64 decimal)
AT (Guard Time After) Command
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)
<Command Mode Options> AT Command is used
to set/read the time-of-silence that follows the
command sequence character (CC Command). By
default, 1 second must elapse before and after
the command sequence character.
The default sequence used to enter AT Command
Mode is as follows:
•
No characters sent for 1 second [BT (Guard
Time Before) Command]
•
Send three plus characters “+++” [CC (Command Sequence Character) Command]
•
No characters sent for 1 second [AT (Guard Time After) Command]
All of the values in this sequence can be adjusted. AT Command is used to adjust the period of
silence that follows the command sequence character.
