Blynk Device Streaming Protocol

Bi-directional low-latency streaming connection protocol used by the Blynk Library and Blynk.Edgent to maintain a persistent link between devices and Blynk.Cloud. Optimized for constrained MCUs (Arduino, ESP32, ESP8266, Particle, Raspberry Pi), the protocol delivers virtual-pin reads and writes, widget property updates, and remote commands without the overhead of polling the HTTPS Device API. Surfaced to firmware developers as the Blynk Library C++ API.

Blynk Device Streaming Protocol is one of 3 APIs that Blynk publishes on the APIs.io network.

Tagged areas include IoT, Streaming, Real Time, Bidirectional, and Firmware. The published artifact set on APIs.io includes API documentation.
