Examples
connection.on(CONNECTION_EVENTS.DEVICE_CHANGE, ({ port, state, type, device }) => {
console.log(`${device.name} ${state}`);
});
connection.on(CONNECTION_EVENTS.OUT_DEV_CONNECTED, ({ device }) => {
console.log(`Output connected: ${device.name}`);
});// Using the short alias (CONN)
connection.on(CONN.DEVICE_CHANGE, ({ device, state }) => {
console.log(`${device.name} ${state}`);
});
