I’ve been trying to get my app to connect a Bluetooth device using Thunkable. It’s a very simple app. All it does is scan for a particular device name and connect to it. However, I can’t seem to get it to connect. I followed all the steps in the tutorial. But I keep getting the following error when it tries to connect using the device name: Device XXXXXXXX was disconnected.

What am I doing wrong?

In a situation like this, you’ll want to declare what happens when an **error occurs first**. Which means instead of saying `if not error`, you’d switch your sections in the if block around and put it as:

```auto
if error:
  set stored variable Error to join:
    "Error Connecting",
    newline
    ERROR MESSAGE
  navigate to ScrnError
else:
  set stored variable DeviceID to DEVICE ID
  navigate to ScrnSteps

```

If you’re planning to save this device to the app until deletion, then keep your variables as a stored variable. Otherwise, use an app variable.

I tried changing it around but it still didn’t work. I’m able to connect to a virtual Bluetooth device that I created with LightBlue so I’m beginning to think it might have something to do with the Bluetooth device that we’re using.
