No Bluetooth or Sensors in component list

Hi, I am a complete beginner with Thunkable. I have no Bluetooth or Sensors in component list to select? What do I have to do? Thanks

Thunkable has 2 different designer platform, namely StP (Snap to Place, also called Legacy) UI and DnD (Drag and Drop) UI.

In DnD all sensors and other invisible components are in the blocks screen not in the design screen.

Thanks Muneer, just found them in the blocks screen as you said. But when I drag a scan block out and place it is greyed out? Any help would be appreciated

Hi there,

Did you connect the scan block to other blocks inside your project?
If a block is greyed out, that means that it is not connected to other blocks, and it will never be executed in your project.


Ahh, thanks Jane.
That’s what I hadn’t done.
Complete beginners error.


You only need to add one of each sensor. Once you have added a sensor, you will not be able to add another one.

Let me know if you have any questions about re-using sensors in your project!
