Hi i have been trying to use moblie broadband by using data card with a huawei 4g dongle. The data card is totally working (singtel hi card)
the dongle i m using is huawei e3372 4g/lte
Thanks in advances for the all helps!
Setting up the 4G/LTE dongle
On the Jetson Nano, setting up the dongle will be a tedious process as the kernels themselves do not come with the driver(huawei_cdc_ncm) included. To do this, we have to build our own kernel.
Steps to configure the dongle:
Firstly, clone the BuildKernelAndModules in the Jetsonhacks Nano repository in github, GitHub - JetsonHacksNano/buildKernelAndModules: Build the Linux Kernel and Modules on board the NVIDIA Jetson Nano Developer Kit
Open the folder where it is downloaded, it should be in your home directory.
Once you located your buildKernelAndModules folder, run the following codes
- ./getKernelSources.sh
- ./makeKernel.sh
- ./makeModules.sh
- ./copyImage.sh
These steps will take awhile(especially the makeKernel and makeModules scripts)
Once everything is downloaded, run the ./editConfig.sh
In the config settings,
Enable these following settings :
Device Drivers —>
[*] Network device support —>
[*] PPP (point-to-point protocol) support – PPP
[M] PPP BSD-Compress compression – PPP_BSDCOMP
[M] PPP Deflate compression – PPP_DEFLATE
[M] PPP MPPE compression (encryption) – PPP_MPPE
[M] PPP over Ethernet - PPPOE
[*] PPP support for async serial ports – PPP_ASYNC
[M] PPP support for sync tty ports – PPP_SYNC_TTY
[*] USB support —>
<*> USB Serial Converter support —>
[*] USB Serial Console device support – USB_SERIAL_CONSOLE
[*] USB Generic Serial Driver – USB_SERIAL_GENERIC
[*] USB driver for GSM and CDMA modems – USB_SERIAL_OPTION
The * means it is built as a kernel, the M denotes it is built as a Module.
To enable these in the config file, type ‘y’ to enable it as a kernel, ‘m’ to enable it as a module.
Once this is done, save and exit the file.
Run ./makeKernel.sh and ./makeModules.sh to build the new kernels.
Run ./copyImage.sh to copy the image to the boot folder.
Reboot the jetson by:
Sudo reboot now
You should have successfully enabled the 4G huawei dongle! However, it will still not work as you still have not configured the APN for the dongle.
Ctrl+alt+t to open a new Terminal.
Install ModemManager and NetworkManager by running these 2 codes :
sudo apt-get install modemmanager
sudo apt-get install network-manager
Run lsusb to check if the dongle is connected
You should see this : 12d1:1506 Huawei Technologies
Once you confirmed that the dongle is connected, run mmcli -L to see if it is detected as a modem.If they mentioned “modemmanager process in the bus unavailable”, you have to enable ModemManager as a service and start it on boot:
sudo systemctl enable ModemManager
sudo systemctl start ModemManager
Run mmcli -L again and you should have detected a modem with a number at the end.
Run mmcli -L x (replace x with the number of the modem)
This will show you the full modem settings.
Check whether the dongle is configured and to confirm whether the device is
detected:
nmcli d
Next type this in the Terminal :
nmcli c add type gsm ifname ttyUSB0 con-name sandbox_lte apn
sandbox.singtel.com ipv4.dns “8.8.8.8,8.8.4.4”
Sandbox_lte is the connection name, it can be anything you set it to be.
sandbox.singtel.com is the APN and it has to be exactly the same.
Type these into the Terminal:
nmcli c edit sandbox_lte
goto ipv4
set dns 8.8.8.8, 8.8.4.4
verify
save
Activate
However, we failed at the last step, the connection activation was not successful
