5 Software and Tools
Huawei can provide the firmware, PC driver, dashboard, and software. The firmware
runs on the module; the PC driver and dashboard run on the PC and communicate
with the firmware to realize all module functions. Huawei can also provide the
software for upgrading the firmware and debugging the problems.
5.1 Firmware
The firmware is software on the module. It accepts commands and data from the host
through USB. The host can send AT commands to enable the firmware to connect,
disconnect, or query.
5.1.1 Version Descriptions
In the version number, the front digits is the firmware version that can differ which
version is newer. The upper bits (except the last two bits) has boarder meaning in the
version name. If the customer has special order to our common version, the order will
be implemented in special version. The version is named by last two bits, but the
front bits are still the common version.

A driver is a program running on the host system, which allows the host system to
interact with the Huawei wireless module. The driver communicates with the firmware
of the module by using the USB protocol.
