None
Stop
1 bit
Flow Control
None
8. Press OK to save the settings and to return to the terminal.
Note: Assuming all settings have been set properly, you should now be able to communicate with
the WB45NBT. The terminal presented now is the Linux shell onboard the WB45NBT, and
behaves likewise.
9. Slide the Power switch (shown in Figure 2) to either the From DC Jack or From USB Power Port to
match your chosen method of powering the BB45NBT board to apply power to the WB45NBT. The Red
LED D20 will light on the BB45NBT board.
Wait until the WB45NBT has completed booting and you see the prompt:

Important Note About “No Serial Output”
In some BB45NBT boards, the UART_3V3 jumper nearest the Debug UART port can become loose or
unseated, which results in no serial output.

Laird CLI Basics
The Laird CLI provides a command line interface to control the Wi-Fi features of the WB45NBT.
The Linux shell prompt is represented by the “#” symbol. From the prompt, enter sdc_cli to start the Laird
CLI. When the Laird CLI starts, the prompt will change to “sdc#”.
Full information on the commands available within the CLI is available from the Laird website.
Information regarding using the CLI commands is also available by typing help at the sdc# prompt.
Additional help is available for the commands iface,profile,global and auto-profile using the syntax
<command> help at the sdc# prompt.
To see the status of the WB45NBT, type status at the sdc# prompt. The returned status should resemble
the following.
Status: AP mode
Config name: Default
SSID:
Channel: 0
RSSI: 0
Device Name:
MAC: 00:17:23:e0:38:e4
IP: 192.168.1.1
AP Name:
AP MAC:
AP IP:
Bit Rate: auto
Tx Power: 0 mW
Beacon Period: 0
DTIM: 0
The WB45NBT defaults to start in AP mode. This allows the user to associate and attach to the WB45NBT as
one would a normal access point and use the integrated Laird WebLCM tool to configure the WB45NBT. The
Status line highlighted in yellow above shows that the WB45NBT is operating in AP mode.

To exit from the sdc# prompt at any time, enter the command exit. You will be returned to the Linux shell
prompt, #.
Configuring the WB45NBT with WebLCM
Once the WB45NBT is operating in AP mode, you may configure the WB45NBT using the WebLCM tool. To
configure the device, complete the following steps:
1. Associate your computer with the WB45NBT by scanning the available Wi-Fi access points in your area.
Connect to the wb45n_xxxxxx AP where xxxxxx is the last 3 octets of the MAC address (highlighted in
blue in the status example above). For the device example above, the device’s SSID name would be
wb45n_e038e4.
Note: Wi-Fi access is protected by WPA2-PSK level security. When prompted by your computer’s
Wi-Fi client, enter the default password, which is lairdtech.
2. Open your web browser and enter the IP address 192.168.1.1 in the address bar. The WebLCM server
uses a secure link running over the https protocol. The certificates used will not be signed by your
browser, so you will see a warning similar to that shown in Figure 5 (this example shows the warning
in Google Chrome):
Figure 5: Accept the certificate issued by the WB45BNT
3. Click Proceed Anyway button (or the equivalent to “Continue” on your browser).
4. Log in to the web server. The user name is root and password is summit. When you log in, you are
directed to WebLCM’s Status tab as shown in Figure 6 .

Figure 6: The WebLCM Status tab
5. Click the Wifi tab to display the profiles page. Here, you may add your required Wi-Fi profiles.
6. When you have added a profile or profiles to the WB45NBT, you must select a profile to make active.
Select the desired profile from your list and click Activate. The profile will now be active when AP mode
is disabled.
Note: You must create an active profile prior to disabling AP mode.
7. To disable AP mode, click the Advanced tab and then click Disable in the AP Mode section.
8. Check the status of the AP connection by typing sdc_cli status at the command line in your terminal.
Note: The web server that hosts the WebLCM on the WB45 is passively waiting for a connection
attempt to the WB45 on port 80. Once a connection attempt is made on that port, the
WebLCM will become active for a period of 10 minutes. If no activity is detected for 10
minutes then the web server will return to a passive state where it is waiting for a connection
on port 80.
