Supported Hardware

There are different ways to get your devices connected to the Blynk Cloud:
  • Blynk library An easy to use and portable C++ library, pre-configured to work with hundreds of development boards. The library implements a streaming connection protocol (i.e. the device stays always connected to the cloud), that allows for a low latency, bi-directional communication. For an easy start use Quickstart flow and make sure to explore Blynk Library documentation afterwards.
  • Blynk.Edgent Blynk.Edgent is a packaged solution that allows developers to easily connect their devices to the platform and take advantage of all its advanced features without the need for extensive coding. It includes:
    • Blynk library API
    • Blynk.Inject (dynamic device credentials provisioning)
    • Blynk.Air (firmware OTA updates)
    • A simple UX/interaction example:
      • Device state indication using an RGB LED
      • Device configuration reset using a button
      If your hardware supports Blynk.Edgent, we recommend using this flow at all times.
  • Blynk.NCP Blynk offers a software stack for a variety of Network Co-Processors. NCP is a dedicated connectivity chip/module that off-loads the Blynk.Cloud connectivity (WiFi, Ethernet, Cellular) from the main device MCU. The main MCU runs a lightweight client library that communicates to the NCP over UART or SPI. It enables blazing fast and high quality integration, and is perfect for retrofitting scenarios. If you're interested in using Blynk.NCP for commercial applications, please contact Blynk.
  • HTTP(s) API A standard communication protocol that can be used by any Internet-connected device. The device connects to the cloud occasionally to transfer the data. Sending timestamped data in batches is also possible, which is particularly useful for Cellular devices. You can find more guidance in HTTP(s) API documentation.

Hardware that works with Blynk library or HTTPs API (using Static Tokens)

This is the easiest way to migrate from legacy Blynk projects. Just add BLYNK_TEMPLATE_ID and BLYNK_TEMPLATE_NAME at the top of your firmware (prior to any includes), update your auth token and that's it. Read more about project migration.

Traffic optimization is usually required for cellular connections. Using realtime streaming protocols like Blynk or MQTT has benefits of interactive device updates, but it also requires device to stay "always connected", which significantly increases the traffic. Blynk recommends using HTTPS (batch) API for reporting telemetry and fetching DataStream values periodically in such scenarios. It will also help saving the battery.
