TODO: Write a small intro here
Install usb_modeswitch and wvdial:
sudo apt install usb-modeswitch wvdialNote: If the installer gets stuck on wvdial, run: sudo killall wvdialconf
Update the file /etc/wvdial.conf so it looks the same as the files in this repository.
NOTE: Remember to set the correct pin of the SIM card, or disable the PIN on the SIM card and remove the PIN line from the config. It is recommended to remove the SIM pin as this removed the bound of which 4G modem to use on the drone.
Add the following files at the following locations:
- The file
2001:ab00, in the./usb_modeswitch.d/directory, to/etc/usb_modeswitch.d/, with:
sudo cp ./usb_modeswitch.d/2001\:ab00 /etc/usb_modeswitch.d/
- The file
modem_attachment.shto/usr/sbin/and make it executable with:
sudo cp modem_attachment.sh /usr/sbin/
sudo chmod +x /usr/sbin/modem_attachment.sh
- The file
modem-attachment.serviceto/etc/systemd/system/with:
sudo cp modem-attachment.service /etc/systemd/system/
- The file
lte-dwm222.rulesto/etc/udev/rules.d/with:
sudo cp lte-dwm222.rules /etc/udev/rules.d/
Add the following lines to /etc/network/interfaces, so the connection is directly used:
# 4G connection
auto ppp0
iface ppp0 inet wvdial
Now after a reboot the 4G stick will be detected automatically.
Make the modem switch from USB Storage Mode to Modem Mode:
sudo usb_modeswitch -v 0x2001 -p 0xab00 -M "55534243123456780000000000000011062000000100000000000000000000"Load serial drivers to communicate with AT interface:
sudo modprobe option; sudo sh -c "echo 2001 7e35 > /sys/bus/usb-serial/drivers/option1/new_id"Connect to the internet using wvdial:
sudo wvdial &You should now have a working 4G LTE connection!
