3 Software Operation Guide
3.1 Button
ED-GWL2110 has a user-defined button. On the back of GWL2110 PCBA, it is connected to the GPIO23
pin of CPU, which is high by default and low when the button is pressed.
We use the raspi-gpio command to test, and query the GPIO23 pin when the key is not pressed.
raspi-gpio get 23
GPIO 23: level=1 fsel=0 func=INPUT
Level of 1 indicates that the GPIO23 pin is high.
When the key is pressed, query the GPIO23 pin.
raspi-gpio get 23
GPIO 23: level=0 fsel=0 func=INPUT
Level of 0 indicates that the GPIO23 pin is low.
3.2 LED Indication
ED-GWL2110 has an RGB tricolor LED indicator. Corresponding to the GPIO pin of CPU is as follows:
RGB LED PIN
GPIO
Blue
GPIO16
Green
GPIO20
Red
GPIO21
When the GPIO output is low, the corresponding LED is valid.
We use the raspi-gpio command to operate, and the configuration parameter is op, which means output

3.3 Ethernet Configuration
ED-GWL2110 has an adaptive 10/100/1000 Mbsp Ethernet interface.
The official system of Raspberry Pi uses dhcpcd as the network management tool by default.
Static IP can be set by modifying/etc/dhcpcd.conf. For example, eth0 can be set, and users can set
wlan0 and other network interfaces according to their different needs.
interface eth0
static ip_address=192.168.0.10/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1
3.4 LTE 4G
Before using 4G, we need to add ourAPT library first. All the images given by our company have been
added with this library, so users don't need to add it manually.
sudo apt update
sudo apt install ed-ec20-qmi

EDATechnology Co.,LTD–Electronics Development Accelerator
Automatic dialing is not started by default. If users want to start automatic dialing, they need to enable
LTE lte-reconnect.service service.
sudo systemctl enable lte-reconnect.service
sudo systemctl start lte-reconnect.service
After successful dialing, you can use the ifconfig command to see the wwan0 network port.
If you need to setAPN additionally, you need to modify the dialing command in/usr/share/ed-ec20-
qmi/LTE-reconnect.sh.
$BSP_HOME_PATH/quectel-CM -4 -f $LOGFILE &
The quectel-CM dialing configuration information is as follows:
$BSP_HOME_PATH/quectel-CM -4 -f $LOGFILE -s <APN> &
Restart lte-reconnect.service after setting.
sudo systemctl restart lte-reconnect.service

3.5 WiFi
ED-GWL2110 support 2.4 /5.8 GHz IEEE 802.11 b/g/n WiFi。
The official system of Raspberry Pi uses dhcpcd as the network management tool by default.
sudo raspi-config
1. Choose 1 System Options。
2. Choose S1 Wireless LAN。
3. Select your country in the Select the country in which the pi is to be used window, and then select

3.7 SD Card Extended Storage
3.7.1 Mount
You can install the storage device in a specific folder location. It is usually done in the /mnt folder, such
as /mnt/mydisk. Please note that the folder must be empty.
1. Insert the storage device into the USB port on the device.
2. Use the following command to list all disk partitions on Raspberry Pi:
sudo lsblk -o UUID,NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL,MODEL
Raspberry Pi uses mount points/and /boot. Your storage device will appear in this list, along with any
other connected storage devices.
3. Use the Size, Label and Model columns to identify the name of the disk partition that points to your
storage device. For example, sda1'.
4. Run the following command to get the location of the disk partition:
sudo blkid
For example, display, /dev/sda1
5. Create a target folder as the mount point of the storage device. The mount point name used in this
example is mydisk. You can specify a name of your choice:
sudo mkdir /mnt/mydisk
6. Mount the storage device at the mount point you created:
sudo mount /dev/sda1 /mnt/mydisk
7. Verify that the storage device has been successfully mounted by listing the following:
ls /mnt/mydisk
tip：No-Desktop system will not automatically mount external storage devices.

User Manual of ED-GWL2110
EDATechnology Co.,LTD–Electronics Development Accelerator
3.7.2 Unmount
When the device is turned off, the system will unmount the storage device so that it can be pulled out
safely. If you want to uninstall the device manually, you can use the following command:
sudo umount /mnt/mydisk
If you receive a "destination busy" error, it means that the storage device has not been unmounted. If no
error is displayed, you can safely unplug the device now.
3.7.3 Set Automatic Mount in The Command Line.
You can modify the fstab setting to mount automatically.
1. First, you need to get the disk UUID.
sudo blkid
2. Find the UUID of the mounted device, such as 5C24-1453.
3. Open the fstab file
sudo nano /etc/fstab
4. Add the following to the fstab file
UUID=5C24-1453 /mnt/mydisk fstype defaults,auto,users,rw,nofail 0 0
Replace fstype with the type of your file system, which you can find in step 2 of "Mounting storage
devices" above, for example, ntfs.
5. If the file system type is FAT or NTFS, add umask = 000 immediately after nofail, which will allow all
users to have full read/write access to every file on the storage device.
Information about more fstab commands can be viewed using man fstab.
3.8 RTC
The default shipping system image will integrate the RTC automatic synchronization service we wrote,
so guests can automatically synchronize the clock without setting it, and can use RTC without feeling.
The general principle is:
When the system is turned on, the service automatically reads the saved time from RTC and
synchronizes it to the system time.
If there is an Internet connection, the system will automatically synchronize the time from the NTP
server and update the local system time with Internet time.
When the system is shut down, the service automatically writes the system time into RTC and
updates the RTC time.
Because button cell is installed, although the equipment is powered off, RTC is still working to time.
In this way, we can ensure that our time is accurate and reliable.
WARN：If it is the first time to boot, because there is no effective time in RTC, synchronization

User Manual of ED-GWL2110
EDATechnology Co.,LTD–Electronics Development Accelerator
may fail, so just restart it directly. When rebooting, the system time will be written into RTC for
normal use.
If you don't want to use this service, you can turn it off manually:
sudo systemctl disable rtc
sudo reboot
Re-enable this service:
sudo systemctl enable rtc
sudo reboot
Time to read RTC manually:
sudo hwclock -r
2022-11-09 07:07:30.478488+00:00
Manually synchronize RTC time to the system:
sudo hwclock -s
Write the system time into RTC:
sudo hwclock -w
Trouble Shooting
Please first check whether there is an rtc device (/dev/rtc0) mounted:
ls /dev/rtc0
If not, maybe you used the official standard system, but didn't install our BSP package. Please install ed-
rtc package to enable RTC automatic synchronization.
Other possible checkpoints:
Is CR1220 installed in button cell?
NTP network time protocol, you need to connect to the Internet to synchronize the time
automatically, and you need to open the port (UDP, 123), otherwise the synchronization will fail.
3.9 Watch Dog

You need to install ed-gwl2100-wdt.dtbo to use watchdog module. File link: todo.
Users need to put it on the device after downloading it. You can use scp command to copy the file to the
device directory:
scp /path/ed-gwl2100-wdt.dtbo pi@ip-address:/home/pi
sudo cp /home/pi/ed-gwl2100-wdt.dtbo /boot/overlays
sudo chmod +x /boot/overlays/ed-gwl2100-wdt.dtbo
And add the following at the end of /boot/config.txt:
sudo nano /boot/config.txt
dtoverlay=ed-gwl2100-wdt
3.10 GPS
ED-GWL2110 gateway integrates L76K GPS module, which is connected with UART0 serial port of
CPU. The module reports GNSS information through NMEA 0183 general protocol output statement.
3.10.1 Pin Configuration
The WakeUp signal of L76K GPS module is connected to GPIO4. If the pin module is pulled down, it will
enter standby mode, and if it is pulled up or suspended, it will return to continuous mode. The Reset
signal is connected to GPIO5. Pulling this pin low for 100ms will reset the module. SET signal is
connected with GPIO6, which is used to configure the satellite combination. When the pin is suspended
or high level, the satellite combination is GPS and Beidou, and when the pin is low level, the satellite
combination is GPS and GLONASS.
