Blynk developer hub: resources and tools

Getting started, documentation, libraries, supported hardware, connectivity, protocols, community—everything you need to build an amazing IoT project.

Pick your way to connect to Blynk

Blynk.Edgent (recommended)

Cloud connection, data exchange, WiFi provisioning, OTA firmware updates and more for supported boards and dual-MCU configurations (NCP).

Documentation
MQTT API

Ideal for projects utilizing MQTT libraries, Node-RED and similar, or SDKs with MQTT support as well as integrating off-the-shelf MQTT-enabled gateways and hardware.

Documentation
HTTPs API

Blynk HTTPs RESTful API allows to easily send and get data from hardware, cloud, and apps using HTTPs requests including sending timestamped data in batches.

Documentation
Blynk.NCP

NCP handles Blynk.Cloud connectivity (WiFi, Ethernet, Cellular), offloading this task from the main device's MCU.

Main MCU operates with a lightweight client library, communicating with the NCP via UART or SPI.

Ideal for retrofitting scenarios.

Documentation
Blynk library

Portable C++ library, pre-configured to work with hundreds of dev boards.

Low latency, bi-directional communication through a streaming connection protocol.

Follow this quick wizard to manually get any device connected to Blynk and get an idea of how it all works.
