ssh communication over Ethernet and USB Ethernet
It is also possible to communicate with the WB50NBT CLI from the host using ssh over USB Ethernet and if
required Ethernet.
USB Ethernet
You will need the USB A to USB B cable for this operation.
The USB Ethernet IP address defaults to 192.168.3.1.
Plug the USB A connector into your host and the USB B into the USB Device connection on the BB40NBT board.
IP Address Setup
On Ubuntu the USB drivers should load automatically. The IP address of the host connection will need to be
configured manually to match the following.
Address:192.168.3.2
Netmask: 255.255.255.0
Gateway: 192.168.3.1
DNS servers: 8.8.8.8
Once the connection to the WB50NBT has been established an ssh client (e.g. putty) can be used on the host to
connect to port 22.
Ethernet
If required, it is possible to connect via ssh to the WB from the host over Ethernet however this first requires
modification of the /etc/network/interfaces file on the WB to change the default behavior of the Ethernet port.
This first requires using the serial or USB Ethernet interface as described above to access the WB over the CLI.
Further instruction on changing the /etc/network/interfaces file is available in the Reference Manual.
Laird CLI Basics
The Laird CLI provides a command line interface to control the Wi-Fi features of the WB50NBT.
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 changes to
sdc#
.
