Same happens with the iOS 13.4.5 beta version released couple days ago.Hope this will be fixed soon due to the huge impact to BLE companion applications. Some words from Apple's would be much appreciated.

We do have a device that have the same disconnection behavior.But more over, the iOS BLE behavior is now the same as Mac OSX (Catalyst) behavior.Our device have all the basic device info like (serial number / manufaturer name / harware revision / firmware revision, etc ...) and we have disconnection after around 20 seconds after connection.
Hello,With the latest iOS 13.4.5 beta 3 BLE doesn't disconnect after 20 secondes by itself. Problem seems fixed.Thank you moderators for your answers and support.
