IoT relies on exchanging information between a myriad of devices and sensors, all of which need to communicate with each other and often with the cloud or other servers. The most exciting Internet of Things features are the possibility of using data transmission between nodes, between nodes and servers, and the ability to read measurements and control the behaviour of devices remotely. All these features use networking functionality. IoT networking is the backbone of the IoT ecosystem, enabling devices to collect and transmit data, receive instructions, |

| Network programming is specific to IoT devices. It uses hardware built into the microcontroller or as an external communication coprocessor connected to the main MCU using one of the popular embedded systems protocols. Many IoT MCUs include a variety of programmable communication radios. Wired communication is possible with external modules (if at all). On the low ISO/OSI layers, the most popular implementations include 802.11 (a variety of WiFi standards) and 802.15 (Bluetooth, Thread, Zigbee and so on). Most modern radios implement many standards and use SDR (Software Defined Radio), but due to constrained resources, use of all standards in parallel may not be possible.\\ | Network programming is specific to IoT devices.

| In the first part of this chapter, the emphasis will be put on the ESP8266 SoC, and all the examples will present software for this chip. The second part of the chapter presents some Scripting examples in Python (and Micropython) for the Fog and Edge classes of IoT devices.\\ | In the first part of this chapter, the emphasis will be put on the ESP8266 SoC, and all the examples will present software for this chip.
