Espressif Systems unveils new communication technology - ESP-NOW!

Espressif's ESP-NOW is an innovative wireless communication protocol designed for Smart and IoT devices. This technology enables direct, fast, and energy-efficient control of devices without the need for a router. ESP-NOW works perfectly with Wi-Fi and Bluetooth LE and supports various SoCs from the ESP8266, ESP32, ESP32-S, and ESP32-C series.

Key features of ESP-NOW:

• Compatibility: The protocol supports a range of SoCs from Espressif, including the ESP8266, ESP32, ESP32-S, and ESP32-C series, making it easy to integrate into various IoT solutions.
• Low power consumption: ESP-NOW is designed with minimal power consumption in mind, making it an ideal choice for battery-powered devices such as sensors and remote switches.
• Data security: To ensure complete data protection, ESP-NOW uses security protocols such as CTR with CBC-MAC (CCMP) to ensure high protection of transmitted information.
• Fast response times: This protocol features extremely fast response times – devices can respond in as little as about 150 milliseconds after receiving a command.
• Flexible device pairing: Enables a variety of communication modes, including one-to-one, one-to-many, and many-to-many configurations, increasing its functionality in extended IoT ecosystems.
• Long-distance communication: ESP-NOW enables long-distance and multi-hop communication, allowing devices to be controlled even in large spaces without the need for additional intermediary devices.

Examples of ESP-NOW applications:

• Smart home appliances: ESP-NOW is widely used in smart home systems, such as controlling lighting, sensors, and other devices that require fast response and low power consumption.
• Remote control systems: The technology enables reliable control of devices, such as remote-controlled cars, airplanes, and robots, that need immediate responses, especially over long distances.
• IoT solutions: In IoT ecosystems, ESP-NOW allows seamless communication between multiple devices, reducing network load and minimizing latency.

Examples of ESP-NOW-compatible products:

• ESP32-C2 button battery-based switch: This is a low-power Wi-Fi switch that does not require a gateway or additional receiver chip, offering fast response time and long battery life.
• ESP32 Wi-Fi Remote Controller: It enables instant control of ESP32-powered devices, such as toys, robots, or other smart devices with millisecond-level latency.

ESP-NOW is a future technology that is already revolutionizing communication in smart devices. Its efficiency, low power consumption, and versatility are driving more and more IoT projects to use this protocol to build modern solutions.
