When I connect with "(SBT_RESULT) sbtEstablishCommunicationSession:(int)scannerID" the device appears in iOS settings. And After if I don't disconnect with "(SBT_RESULT) sbtTerminateCommunicationSession:(int)scannerID" (connection is interupted for other reasons), scanner is still listed in iOS settings. Sometimes what then happens is that I cannot connect back to the scanner with "(SBT_RESULT) sbtEstablishCommunicationSession:(int)scannerID" connections fails and it is possible to connect only if I unpair the scanner manually. But that shouldn't be neccessary. I'm not sure if that is an issue with the SDK or firmware. Can you please advice?
