It holds information related to your location and therefore making devices available for two-way communication. IP or Internet Protocol defines the set of commands directing the setup of data transferred through the internet or any other local network.Īn IP address is the identifier that enables your device to send or receive data packets across the internet.

The following sample code makes the led connected to the digital0 port blink.Next → ← prev IP address An IP address represents a unique address that distinguishes any device on the internet or any network from another. Code is programmed through the web interface and then published to the MCU board. It allows Javascript or Python programming of the MCU-PT microcontroller. Real world MCU are for example Arduino boards like the Arduino Yún ShieldĪn IoE programming editor is included in the Home Gateway web interface. The Home Gateway relies on the remote control API eventually programmed on the MCU-PT to get the sensor's status. The MCU-PT is connected to the gateway which only sees the microcontroller board but not the IoE components. These smaller sensors or actuators are connected to a microcontrollers (MCU-PT) card. IoE components in Packet Tracer 8.2 Connecting IoE componentsĪs they don't have ethernet interface, IoE components can't be directly connected to the Home Gateway. MQTT protocol and applications have been added in Packet Tracer since version 7.1 to improve communications between IoT devices Sensors: these components sense the Environment (photo detectors, temperature sensor), the area around them (RFID, metal sensor), or interactions (potentiometer, push button).Actuators: these components manipulate the Environment, themselves, or the area around them.Boards: microcontrollers (MCU-PT), single boarded computers (SBC-PT), and a special device called Thing which are used to create self-contained physical objects like coffee makers or smoke alarms.There are three subcategories for Components : These are simple devices that only communicate through their analog or digital slots. They typically does not have a network interface and rely on the MCU-PT or SBC-PT for network access.
