I have used bluepy library to interface to the BTLE Devices but that has proved unreliable at best. I'm not sure where the problems lie but basically sometimes to connect I have to disconnect the USB BT Dongle and re-insert it to get BlurTooth to work. I can scan and find the devices I'm looking for but as soon as a connection is attempted I just get a null return from the connection function. At present that means that bluetooth is not ready for production on the linux device we're using. I'll try get the device into that state and try connect with command line tools, just in case it gives some indicaiton of what the problem actually is. At present there's no indication. I'm sort of hoping that this is an issue with bluepy and I'll move to another interface and see if that makes this any more reliable. It's for an LE sensor for IoT in a production line, so unreliable is worst then useless. Thanks again for your help John
