Guides covering wireless communication technologies such as WiFi, Bluetooth, LoRa, RF modules and infrared protocols. We will talk about topics like range, data rates, interference, pairing, power consumption, and practical implementation of wireless communication between devices.
MQTT is a lightweight messaging protocol designed for efficient communication between devices over networks. It is widely used in IoT systems where bandwidth, power consumption and reliability are important. Unlike traditional request-response protocols such as HTTP, MQTT uses a publish/subscribe model, which makes it highly efficient for real-time data exchange. What Is MQTT? MQTT stands […]
WiFi is one of the most widely used wireless communication technologies in modern electronics. It allows devices to connect to local networks and the internet without physical cables, making it essential for IoT systems, smart home devices and embedded controllers. For microcontroller-based systems such as ESP32, WiFi enables direct communication with servers, mobile apps and
Bluetooth is a widely used wireless communication technology designed for short-range data exchange between devices. It is commonly used in smartphones, headphones, sensors, microcontrollers and many embedded systems. In microcontroller projects, Bluetooth allows direct communication with smartphones, tablets and computers without requiring a WiFi network. What Is Bluetooth? Bluetooth is a wireless communication standard that
Bluetooth Low Energy (BLE) is a wireless communication technology designed for very low power consumption and efficient data transfer. It is widely used in modern IoT devices such as sensors, wearables, smart home devices and battery-powered systems. Compared with classic Bluetooth, BLE is optimized for short bursts of data rather than continuous streaming. What Is
LoRa is a wireless communication technology designed for long-range, low-power data transmission. It is commonly used in IoT systems where small amounts of data must be sent over long distances without using WiFi, Bluetooth or cellular networks. LoRa is especially useful for remote sensors, environmental monitoring, agriculture, tracking systems and battery-powered devices. What Is LoRa?
433 MHz RF modules (or 315/868/915 MHz, depending on national regulations) are among the simplest and cheapest wireless modules used in electronics projects. They are commonly used for remote controls, wireless switches, weather stations, sensors, garage-style transmitters and simple Arduino projects. When we talk here about 433 MHz, then the same information apply to the
Infrared (IR) communication is a simple and widely used wireless method for short-range control. It is commonly used in TV remotes, air conditioners, audio systems and many DIY electronics projects. IR is especially relevant for embedded systems because it is inexpensive, easy to implement and works reliably over short distances without radio interference. What Is
TCP and UDP are two of the most important transport protocols used in computer networks and IoT systems. If your microcontroller communicates over WiFi, Ethernet or the internet, it will often use one of these protocols. While both move data between devices, they behave very differently. Choosing the right one affects speed, reliability, latency and
