Hello, either I have implemented the suggestion of confirming the reception of my shutdowncommand and only then closing the connection completely false or it's something quite curious and different:
I found out now that the problem only happens under these conditions: - in my application's setup wizard there's the possibility to search for our Bluetooth devices and automatically pair and set them up. - when I close the wizard mentioned shutdowncommand has to be sent so that some part of my app. quits and is restarted afterwards. - only in the case when my app is running on a Laptop with Toshiba Bluetooth stack equipped and the device to be added to my application is not yet paired the shutdown command never arrives, no matter what I do. If the device has been paired previously everythign works like a charm! I've now contacted the developer of our Bluetooth library (named WCL) and hope he might shed some more light on this matter. I'm clueless now.
