Sending AT Commands
AT commands are short text strings that can be sent to the modem to set, remove and query modem's configuration
parameters. BlueVue Device Manager is a software application that provides a graphical user interface designed to avoid
manual entry of AT commands. However, not all configuration commands are available in BlueVue. Additionally, BVDM
is only available in Microsoft Windows operating systems. For these and various other reasons, some users may want to
send AT commands to the modem.
The full list of AT commands and their description is in the
AT Command Reference
manual, available at
IMPORTANT:
After sending AT commands to configure the modem, you must send
AT&W
to save the changes.
Otherwise, they will be lost the next time the modem resets. You do not need to send AT&W after
each command: you can send it just once after you’re done configuring the modem.
Note:
AT commands must end with a Carriage Return character. If you are not using a Windows
operating system, you may have to configure your terminal emulator software or telnet client
software to end lines with a Carriage Return (0x0D or \r).

Sending AT commands over an IP connection
If you can reach the modem using a crossover Ethernet cable, or a USB cable, or remotely to the modem's WAN IP, AT
commands can be sent by performing a TCP (telnet) connection to the modem on port 6070. Here is an easy way to do
this
in
Windows:
1)
Click the
Start
button, then
Run
.
2)
In the Run window, type
command
and click OK. A command prompt window will open.
3)
Type
telnet xxx.xxx.xxx.xxx 6070
(replacing the x’s with the modem’s IP) and press
Enter
. By default, the modem's IP will be 192.168.0.1 for Ethernet, and 192.168.111.1 for
USB. If connecting to a remote modem, you will need to know its WAN IP.
4)
If the modem is password protected, you will have to enter its password.
5)
You should get a "Welcome to BlueTree Wireless" message. You can now
send AT
commands
.
12.5.2
Sending AT commands over a serial connection
If connected to the modem using a straight DB9 serial cable, AT commands can be sent using a terminal emulation
software. The terminal and the modem must be using identical serial port settings to communicate. By default, the
modem uses 115200 bps, 8 data bits, no parity, 1 stop bit, and hardware flow control. Below is an example for
connecting to a modem with default serial port settings.
