Got the issue. I did not added the following in Info.plist. But I guess it should have been handle and proper TerminalException to be thrown

<key>UIBackgroundModes</key>
    <array>
        <string>bluetooth-central</string>
    </array>

It seems like an error in the official iOS SDK, there's nothing I can do about it :(
