LTE

note

For an API reference, see API Reference/LTE

The LTE module handles all the cellular communication. The API offered to the user allows for starting and stopping cellular communications, as well as registering callback for a disconnect event.

To connect to the cellular network, call Lte.begin(). When this function returns, the modem is connected to the network. The disconnect callback is registered through the Lte.onDisconnect(discCallback) call. The callback have the signature void myCallback(void).

caution

Remember to connect the Antenna to the board before running any examples that use a wireless feature (i.e LTE, MQTT) or web service (i.e AWS, HTTP)

Example

#include <lte.h>
#include <log.h>
#include <led_ctrl.h>

static volatile bool disconnected_event = false;

void disconnectedFromNetwork(void) {
    disconnected_event = true;
}

void setup() {

    Log.begin(115200);
    LedCtrl.begin();
    LedCtrl.startupCycle();

    Lte.onDisconnect(disconnectedFromNetwork);
    Lte.begin();
} 

void loop() {
    if (disconnected_event) {
        Log.info("Got disconnected!");
        disconnected_event = false;

        // Do something when disconnected, e.g. reestablish connection...
    }
}
