LightBlue® Your BLE Debugging & Development Toolkit

Created as a stepping stone for Punch Through clients, the LightBlue® iOS, macOS, and Android apps help teams with simple BLE debugging and prototyping. When our mobile team is between client projects, they spend time helping the development community by supporting and improving LightBlue®.

Great Teams Build Exceptional Connected Products

Why we created LightBlue®

In 2012, we created LightBlue® as an internal tool to help our team test and debug BLE devices while working on client projects. It was a simple solution to a real need — and it quickly became indispensable. Seeing its potential to solve common BLE challenges, we decided to share it with the broader development community.

LightBlue is designed to make BLE testing and prototyping easier, empowering developers to focus on what matters: building innovative solutions. From handling everyday tasks to addressing complex connected device challenges, LightBlue is here to support your work.

We made LightBlue free because we believe in giving back. As developers ourselves, we know the value of reliable tools that simplify the process, and we’re proud to contribute to the success of BLE developers everywhere.

LightBlue isn’t just a tool — it’s a reflection of our commitment to advancing BLE development for the whole community.
