Written to be used during my thesis work. +Uses the BG96 chip with AT commands, connected through GPIO and serial pins of a Linux machine. Should be easy to adapt the code to other devices using AT commands. +Requires libgpiod. +Compiled and tested with Clang 11.0.1 aarch64. + +Compiling +CMake is used in development. +For development, "celnetmon" target can be used to work in the build folder. +For release, "install" target creates and puts the executable in "./bin". + +Usage +Make sure to create a "celnetmon.cfg" config file in the same folder with the executable. An example "celnetmon.cfg.example" is included in the repo. + +"celnetmon --init" +Powers the BG96 chip on, initiates the GNSS system, configures and connects to the network. + +"celnetmon --publish" +Collects network telemetry and GNSS location, publishes the data to the specified MQTT server in the config file. + +"celnetmon --stop" +Powers the chip down. + +A-GPS technologies are not implemented. For that reason, GNSS takes some time to establish. +Telemetry data that is collected are: +- Network operator name +- Roaming status +- Tracking area code +- Cell ID +- Technology +- Band +- Channel +- Network Time +- GPS location +- Signal quality indicators (BER, RSRP, RSRQ, RSSI, SINR)
