Introduction
The X-CUBE-CELLULAR Expansion Package enables connectivity over cellular networks. The network access technology
depends on the cellular modem used. It can be 2G/3G as well as LTE Cat M1 or NB-IoT.
This user manual provides:
• A brief content description of the X-CUBE-CELLULAR Expansion Package for STM32Cube
• Instructions to start the hardware composed of a board based on an STM32 microcontroller associated with a modem, and
to exchange data through a cellular network by means of X-CUBE-CELLULAR firmware
