Runtime Error trying to replicate the IoT BLE tutorial when running Companion on iOS

Runtime Error: Error from Companion: error: undefined variable. (irritants: yail/edu.mit.appinventor.ble.BluetoothLE)

Any ideas?

Due to Apple App Store Guidelines, extensions on iOS cannot be supported since they load code not approved by App Store Review. We're looking into a way of incorporating various MIT-authored extensions into the iOS version but we don't have an ETA for when those would be supported at this time.

Oh dear, thanks for the response, I’ll have to try Android BLE for now
