3 Steps to IoT Device Connectivity

Build

Add Blues Wireless Notecard to your product with your preferred hardware.

Integrate

Our simple JSON interface allows you to connect and send data with 2 commands.

Configure

With Blues Wireless Notehub, enjoy secure, bidirectional data flow between your device and your cloud app.

How to Evaluate Blues Wireless in 30 Minutes or Less

With Blues Wireless, you'll never worry about monthly or consumption fees.
Each billing account is refreshed to 5,000 credits each month with the ability to purchase more.

Purchase

You can pick a starter kit based on ESP32, Raspberry Pi, or our own feather-compatible microcontroller Swan.

Unbox

Plug the Notecard into the provided Notecarrier, then connect to your existing hardware.

Start

Follow along with our quickstart. In 30 minutes, you'll have a device connected to the global cellular data network, and data flowing from device to cloud, and back to device again.

Tips

  • Feather kit and Swan kit contain MCUs. If you want our Raspberry Pi kit, you'll need your own Pi.
  • Swan lets you write code in C/C++, Arduino, and CircuitPython. It's also a powerful MCU and ready to run on edge-based machine learning like Edge Impulse. We have a guide for that.
