Even if you have the expertise, finding, downloading, and updating Vodafone Mobile Broadband Modem () drivers can still be a tedious and messy process. Locating the right Vodafone Mobile Broadband Modem () driver on ZTE Corporation's website can be very difficult, and can often take a lot of time searching. Don't worry, because these PC problems will probably be fixed after updating your USB Modem drivers. When the operating system that your device depends on gets an update, drivers can suddenly stop working with it. Vodafone Mobile Broadband Modem () errors can be related to corrupt or outdated device drivers.
ZTE has created these "mini software programs" specifically for Vodafone Mobile Broadband Modem () to enable this commiunication. You can then use BSD Sockets or any high-level component ( HTTP Client, NTP Client).Device drivers enable your hardware to be able to communicate to the operating system. To connect to the internet you must establish a PPP connection. You'll notice that this "Hello World" program is a little more complex that others, as we're using the mbed RTOS to manage the memory and processing resources/requirement of the USB Modem driver and the TCP/IP stack.
There are various other "hello world" programs that demonstrate SMS, NTP, Socket and Websocket interfaces, as well as management commands (check balance, link status, etc).
This example application uses the VodafoneUSBModem and the HTTPClient interface, enabling the mbed to fetch a URL over HTTP, and print the contents. In the example show, an external linear regulator board has been used to provide a high current regulated 5V supply from a 9V wall adaptor. Because of the high current that the USB dongle requires, it is not possible to power it from the Vu pin on the mbed.
