Button Command Sender

This example demonstrates a common ArmorLink pattern: local firmware logic sends Commands into the network.

The button remains normal application code. ArmorLink only transports the command.

Complete Example​

#include <ArmorLink.h>

#define BUTTON_PIN 4

ArmorLinkModule module(
    "Left Hand",
    ArmorLinkModuleType::Hand
);

bool lastButtonState = HIGH;

void setup()
{
    Serial.begin(115200);
    delay(500);

    pinMode(BUTTON_PIN, INPUT_PULLUP);

    ArmorLinkOptions options;
    options.nodeName = "Left Hand";
    options.enableGateway = false;
    options.enableEspNow = true;
    options.enableBle = false;
    options.enableSerialLogging = true;
    options.defaultLogTarget = "Chest";

    ArmorLink.begin(module, options);
}

void loop()
{
    ArmorLink.loop();

    bool currentState = digitalRead(BUTTON_PIN);

    if (lastButtonState == HIGH && currentState == LOW) {
        onButtonPressed();
    }

    lastButtonState = currentState;
}

void onButtonPressed()
{
    ArmorLink.debug("Button pressed");
    ArmorLink.sendCommand("Helmet", "Facemask", "toggle");
}

Matching Action on the Target​

module.actions()
    .add("toggleFaceplate")
    .label("Toggle Faceplate")
    .section("Faceplate")
    .command("Facemask", "toggle")
    .onExecute([] {
        toggleFaceplate();
    });

Sending to the Gateway​

ArmorLink.sendCommand("Chest", "BTN_L1", "SINGLE_CLICK");

Use this when the Gateway acts as a central controller.

Broadcast Commands​

ArmorLink.broadcastCommand("Flaps", "toggle");

Every module receives the command. Only modules with a matching Action react.

Typical Use Cases​

  • Hand controllers
  • Hidden suit buttons
  • Reed switches
  • Voice recognition modules
  • Gesture controllers
  • Sensor-triggered actions
