WB-L20B Automatic Start-up Items Check script /etc/init.d/S90init-stuff for WB-L20B startup items, here will explain how to configure and edit each programwhich will run at the start of device. 1.To reviewscript S90init-stuff: vi/etc/init.d/S90init-stuff, as shown in figure 3-1: Figure 3-1 Automatic Start Scripts 2. Script content is as follows:  gpsd.sh -- GPSD configuration script, through which user can configure GPSD serial port and baud rate, the gpsdbaud rate is 115200.  run_wireless.sh -- Load Wi-Fi driver module, after running this script, device will act as an AP, waiting wireless terminal to access by Wi-Fi.  run_ap.sh -- Hostapd configuration script, through whichuser can set IP address pool for client devices.  run_bt.sh -- Bluetooth module loading script, after running this script,Bluetooth function is

IV. WB-L20B Software Use Guidance 4.1 Device Network Interface Introduction After login system, input command “ifconfig” to view device network interface information, as shown in figure 4-1:
WB-L20B User Guide 9 Figure 4-1 Network Interface Info Through “ifconfig”command, there are five network interfaces on the device, namely eth0, lo, usb1, wave0 and wlan0. Eth0 is Ethernet interface, lo is local loopback interface, wave0 is DSRC communication interface and wlan0 is Wi-Fi interface. Please note that SIM card is not plugged in, usb1 interface won't appear. 4.2Wi-Fi Use Guidance Type in command “ifconfig” to view device network interface information, as shown in figure 4-2: Figure 4-2 Wi-Fi Interface The default interface for Wi-Fi is wlan0and default IP address is 192.168.110.1, this is the AP address forother devices to connect to. User can change this IP address by editing corresponding configuration file. See the next section for detail. 4.2.1 Modify Wi-Fi IP Address and Assign IP Address Pool Use vi to open /etc/udhcpd.conf, find “start” and “end” items.
WB-L20B User Guide 10 Figure 4-2-1Wi-Fi Assign IP Address Pool Change the start and end configuration in green spot to modify the address pool of AP.The default IP addresses for client is in 192.168.110.0 segment, totally 10 addresses (From 192.168.110.110 to 192.168.110.120). Note that if you want to modify default address, please make sure that “opt router” item in udhcpd.conf has the same address segment as AP address segment, shown in figure 4-2-2 highlighted in green. Figure 4-2-2 Wi-Fi IP Address Detailed Info 4.3Ethernet Use Guidance 4.3.1 ManuallyConfigure Ethernet Interface IP Address Connect WB-L20B to PC via Ethernet cable, log in and input“ifconfig eth0 up” and“ifconfig eth0 192.169.5.200 netmask 255.255.255.0”. Then eth0 IP address can be seen, as shown in figure 4-3. Note thatWB-L20B and PC must configure in the same network segment. Figure 4-3 ManuallyConfigure Ethernet Interface
WB-L20B User Guide 11 4.3.2 AutomaticallyAcquire Ethernet Interface IP Address Connect WB-L20B to router via Ethernet cable, input “udhcpc -i eth0”, then WB-L20B’s Ethernet interface can obtain IP address automatically, as shown in figure 4-3-1. Figure 4-3-1 AutomaticallyAcquire IP Address 4.4 4G Network Interface Use Guidance Usb1 is the 4G network interface.WB-L20B obtained IP address 10.144.119.118from server. The existence of this address stands that the device is capable of accessing to Internet, as shown in figure 4-4. Figure 4-4 4G Network Interface 4.5 System Upgrading Introduction 4.5.1 Upgrading File Preparation First of all, prepare the upgrade file such as kernel;copy upgrading file to any path of the device. To do this, user can use Linux SCP command under Linux or SSH, WinSCPunder Windows. Now takingWinSCP as an example, the access configuration steps are as follows: 1) Open the WinSCP, configuration interface will appear as shown in figure 4-5; 2) SelectSCP as protocol, use 192.168.2.100 as host name, default 22 as port number, “root” as
WB-L20B User Guide 12 user name and “victgen” as password.Click "login" to complete access. (If host key related security warning appears, select "update".) After accessing using WinSCP shown in Figure4-5-1, with PC’s file directory on the left and WB-L20B file directory on the right.Then user can do file operations. As user has root privilege, please be cautious when applying operations. 4.5.2 Parameter Introduction Viewsys_update.sh under /opt/scripts directory, this script supports four kinds of upgrading, including DTB, Uboot, Kernel and FS. User can use command line to upgrade. (For example,./sys_update.sh -x /xxx/xxxxxx.xxx) 1) -x to distinguish four types of upgrading files:  -d stands for DTB upgrading  -u stands for Uboot upgrading  -k stands for Linux Kernel upgrading  -f stands for Filesystem upgrading  -d、-u、-k、-f can be used in any combination, this means that not only one type upgrading file, but multiple combination files can be used for upgrading. For example,-u, -k, -d, and -f using at the same time means the device needs to upgrade using DTB, Uboot, Kernel and FS files at the same time. Note that parameters are all lowercase letters. 2) /xxx/xxxmeans that upgrade file can locate in any path. 3) xxx.xxxstands for upgrading file name, this name can be user defined and has no format requirements
