What is this?

An SMS-Gateway is a server that provides an API for sending and/or receiving SMS/Text messages. The E303 (and other Hauwei modems) provide a web GUI interface and an XML API for programmatic access. This contains a set of scripts to manage Hauwei modems, including sending/receiving SMS. It has been tested on the Hauwei E303 and E3372.

IP Addresses

Switching to CDC_Ether mode

For API Access, the device needs to run in cdc_ether modem (which is the usual default) Occasionally, it will boot into a different mode and a modeswitch command will be required

# Change to cdc_ether mode
usb_modeswitch -v 12d1 -p 1f01 -M '55534243123456780000000000000011062000000101000100000000000000'

What if 192.168.1.0/24 clashes with my LAN

This workaround is for Linux only.

# Create a network namespace for the HiLink 
sudo ip netns add sms
# Add the hilink to the network namespace and bring it online
sudo ip link dev enp0s29u1u6
sudo ip netns exec sms ifconfig enp0s29u1u6 up 192.168.1.100/24

# Run the hilink commands inside the network namespace 
sudo ip netns exec sms ./hilink_status
