We recently added a new feature to our MESHLE app – a Lighting Editor for Bluetooth Mesh devices. Think of it as a video editor for your lights: define transitions, sync timing, set effects – all on your smartphone or tablet. Simple and convenient, especially for dynamic scenes.
Soon after launching it, we started getting questions from customers using dozens of LED drivers:
“Can we light up an entire building façade?”
“Can we sync the background lighting of a massive printed installation?”
We didn’t know. So we decided to find out.
The Test: 42 Devices, Over 40 Meters Apart
We set up a test environment with 42 MESHLE LED drivers, spaced out across more than 40 meters. Each one ran its own animation, but the goal was a shared visual effect – harsh light pulses and a strobe-style sequence – all timed perfectly.
No wires between them.
No controller in the middle.
No Wi-Fi.
No phone connected during playback.
Everything ran over the Bluetooth Mesh network.
The result? See for yourself in the video below:
What We Learned
Despite the physical spread and number of devices, the lights behaved as if they were all controlled by a single LED driver. Animations remained in sync across all 42 nodes, thanks to how the mesh network distributes timing and resyncs after each loop.
There was no lag, no drift – and most importantly, no central controller required. The Bluetooth Mesh handled everything, exactly as intended.
What’s Next?
While the result was impressive, we’re not done. Handling dozens of devices on a phone screen still comes with UX challenges. Creating complex, beautiful effects with just a few clicks is possible – but there’s room to make it faster, smoother, and more intuitive.
We’ll keep improving the editor. But for now, it’s good to know:
If you want to light up a wall, a stage, or even a full installation — yes, it works.
And it works on Bluetooth Mesh.
