The MTSCellularInterface library implements the mbed-os CellularInterface for the cellular radios on MultiTech Dragonfly devices.

MTSCellularInterface provides TCP and UDP sockets, SMS messaging capabilities, and GPS location*.

After cloning this repository, run the setup script (setup.sh or setup.bat) to generate the version header and clone required dependencies.

To get started with MTSCellularInterface, you just need a pointer to the library.

• Most cellular radios require an APN string to be set before the radio can be used for SMS, TCP, etc.
• The radio will not usually be able to connect until it is registered with the network.

#include "MTSCellularInterface.h"

int main() {
    PinName radio_tx = RADIO_TX;
    PinName radio_rx = RADIO_RX;

    MTSCellularInterface* radio = new MTSCellularInterface();
    assert(radio);

    const char apn[] = "<your APN>";

    // wait for registration
    while(!radio->is_registered()){
        wait(2);
    }

    // connect
    if (radio->connect(apn)) != NSAPI_ERROR_OK) {
        // connection failed - handle the failure
    }

    // connection succeeded
    // SMS, socket, etc functions should be available
}

The Dragonfly-Examples repository demonstrates how to use common MTSCellularInterface features.

The MultiTech Dragonfly mbed platform page has features, pinout information, and other documentation and resources.

* Not all radios support GPS. GPS location requires a lock on GPS satellites, which may not be possible indoors.
