Huawei HiLink Modules
The Huawei HiLink modules provide access to the HTTP API for Huawei USB modems. The E3531 modem is specifically supported but the modules may work for other Huawei USB dongles that provide the HiLink HTTP interface.
The modules provide access to the HiLink API which is not the same as accessing the dongle through AT commands over a serial device.
The API allows you read and send SMS messages, start and stop your data connection and monitor your data usage. HiPi::Huawei::E3531 provides the interface for the only currently tested USB device.
