Package hilink is a Go package for working with Huawei Hilink devices (ie, 3G/4G modems and WiFi access devices).
Install in the normal way:
$ go get -u github.com/kenshaw/hilinkTo use the Go API, please see the full API information on Go ref.
There is a convenient command line tool, hlcli that makes
working with the API extremely easy:
# install hlcli tool
$ go get -u github.com/kenshaw/hilink/cmd/hlcli
# display available commands
$ hlcli help
# get help for a subcommand 'smslist'
$ hlcli help smslist
$ hlcli smslist --help
# get network connection information from non-standard API endpoint
$ hlcli networkinfo -endpoint http://192.168.245.1/
# send sms with verbose output
$ hlcli smssend -to='+62....' -msg='your message' -v
# send ussd code with verbose output
$ hlcli ussdcode -code -vThis was built for interfacing with a Huawei E3370h-153 (specifically a Megafon M150-2) device, popular in Europe and Asia. It was flashed using a custom firmware and WebUI that enables the extra features.
Here is the relevant information taken from the API using the hinfo tool:
$ cd $GOPATH/src/github.com/kenshaw/hilink
$ go build ./cmd/hinfo/ && ./hinfo

}This API is currently incomplete, as I only have one type of Hilink device to test with and because I have not attempted to do an exhaustive list of all API calls. That said, it should be fairly easy to write a new API call by following the existing code. Pull requests are greatly appreciated, and encouraged!
Because the documentation available for the E3372h-153 is so poor, especially for the version that I have (M150-2, identified by the "HardwareVersion" of CL2E3372HM), and very little is available in English, I have decided for posterity to record my notes on installing modified firmware here. These notes should also work for other Huawei devices, but make sure you are using the correct firmware for your device! Incorrectly flashing your Hilink device, or using the wrong firmware will likely brick your device.
Huawei modems with older firmware (circa 2014 and older) are commonly referred to as "stick" devices. These devices can sometimes be flashed with the newer "hilink" firmware versions, however as I only have one hardware revision available to me, I cannot definitely say which can or cannot be flashed. My rudimentary investigation leads me to believe that the vast majority of the Huawei modems on the market can be updated to a Hilink version of the firmware.
For reference, all "stick" firmware starts with "21." and all hilink firmware starts with "22." While some people have had success with getting the stick firmware to work properly with Linux, I personally have not been successful doing that. Additionally, those who have reported getting the stick firmware to work, have reported significantly lower than 4G speeds.
The primary difference between "stick" and "hilink" firmware, is that the stick firmware exposes standard serial ports to the host that work as standard modems. These also have a standard tty interface that one can access and control the internals. The "hilink" firmware instead provides a standard USB ethernet device, with its own subnett'd network and exposes a web interface for controlling the software over the ethernet device. By default, that network provides standard DHCP and is configured to issue addresses in the range of 192.168.8.100-200.
Note that a hilink device can be put into "debug" mode which then exposes a
number of standard /dev/ttyUSB* that can then be used to send AT commands.
This can be done by using this API or by using the usb_modeswitch command
line tool. Please see Go ref or
the usb_modeswitch manpage.
Occassionally when a hilink device is plugged in, the Linux kernel/udev does
not recognize it, and does not properly put the device into hilink mode. The
latest versions of usb_modeswitch are able to deal with this:
$ sudo usb_modeswitch -v 12d1 -p 1f01 -V 12d1 -P 14dc -JThe Huawei E3372h-153 device is a 4G LTE USB modem that works with with all international 4G frequencies. The same hardware is sold as a "stick" model and a "hilink" model -- please see the comments above. Other companies may distribute this same hardware version under other names, and will usually be labeled a E3372h-153 device. I am not sure if the -153 is specific only to Megafon or not, as I have seen others listed (but have not bought) with that model number.
If it is sold as a "stick" model (sometimes listed on the packaging as a E3372s) then it will have the older firmware, and will need to be flashed / updated. Additionally, the stock firmware is missing many useful features, and should be flashed to a modified firmware version.
- Write down the IMEI number listed on the modem (needed if it is running the 'stick' firmware)
