2.4.3 Configuration Using a USB Cable
The evaluation board uses a USB cable to allow the host computer to communicate with
the RN131/171 module on the evaluation board.
The following instructions describe how to use a terminal emulator to go into Configura-
tion mode, send commands to find networks, associate with an access point and save
configuration.
2.4.3.1 CONFIGURE THE MODULE USING A TERMINAL EMULATOR
Either the TeraTerm (for Windows OS) or CoolTerm (for Mac OS-X), terminal emulator
program can be used. Also legacy evaluation boards uses a USB-to-serial cable for
connecting the evaluation board with the computer/laptop. When using either of the
RN131/171 evaluation board, use the COM port to which the USB-to-serial cable is
connected.
The following are the steps to communicate with the module using a terminal emulator:
1. Determine the COM port that is assigned to the USB cable (the port is COM9 in
the example shown in Figure 2-4).
2. Open the available terminal emulation program and specify the COM port.
3. When using TeraTerm, go to Serial option and select the COM port number from
the drop-down menu.
4. The serial port with the required settings are as follows:
- Baud: 9600
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
5. Type the commands through the terminal emulator program and to the assigned
program.
Note: COM port number can be found as follows:
- For Windows OS: Go to the Windows Device Manager, from System Tools. In
the Device Manager, browse and expand the selection for serial ports (COM &
LPT). Use TeraTerm for other configuration settings and monitoring.
- For MAC OS: When using CoolTerm, view and select the port from the same
terminal emulator application.
