I tried to use the permission block but the app give this execution error:
undefined variable. Irritants: (yail/com.google.appinventor.components.common.Permission)
Note: You will not see another error reported for 5 seconds.
Someone can explain me what I did wrong, please.
(note: I'm working with an iPhone as companion)
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

Nothing wrong Adriana. I believe Bluetooth does not yet work with ios. Nothing has probably changed since posting of this discussion Message "Error irritants: yail/edu.mit.appinventor.ble.BluetoothLE" on iOS .
You can do this with an Android device but not yet with ios.
