Blynk's official C++ client library that connects over 400 IoT hardware boards (Arduino, ESP32, ESP8266, Raspberry Pi, Particle, etc.) to the Blynk Cloud IoT platform. It provides the firmware-side API for sending sensor data, controlling GPIOs via virtual pins, and receiving OTA firmware updates.
Use cases
- connect an ESP32 to the cloud and read sensor data from a mobile app
- control Arduino GPIO pins remotely from iOS or Android
- push telemetry from a Raspberry Pi to an IoT dashboard
- add OTA firmware updates to an ESP8266 device
- build a smart home device with a drag-and-drop mobile interface
- connect hardware over WiFi, Ethernet, GSM, or LTE to a managed IoT cloud
- prototype an IoT product with device provisioning and dashboards
When to choose
- you want a low-code IoT platform with hosted cloud, mobile apps, and dashboards
- your project uses Arduino, ESP32/ESP8266, Particle, or other supported boards
- you need OTA updates, device provisioning, and fleet management out of the box
- you prefer not to build your own backend and mobile app for device control
When to avoid
- you need a fully self-hosted, vendor-independent IoT stack with no cloud dependency
- your board or connectivity shield is not among the supported hardware
- you only need raw MQTT or HTTP communication without platform services
- you require full control over firmware networking code with no proprietary cloud
