Hi,
I have an nRF52832 sending data to a central device. At the central side I am testing two tablets (separately). One is a Samsung Galaxy Tab A 2016 10" and another one is an Acer Iconia One 10. The problem is that not only my data transmission stops after while with the Samsung tablet but also the sniffer does not show any packets after the connection request is sent. The sniffer shows clearly all the packets when the Acer tablet is used.
I have the same setup for the testing; same firmware, hardware and Android app. The problem is consistent in all the runs. In every single test the Samsung tablet stops showing the data after a while but the Acer tablet works perfectly in all the tests. Does any one have any idea why this happens?

Extra information on the tablets:
1- Acer: Android version: 5.1 Bluetooth version: 4
2- Samsung: Android version: 6.0.1 Bluetooth version: 4.2
Update 1 I tested with Nordic's app Connect for the Samsung device. The sniffer shows the data but still after a while the data stops. So I was able to see the cause of the termination. The error code is 0x3b (from both sniffer and the Connect app), which means "Unacceptable Connection Interval). But why? I read here that the connection interval must be above 11.25ms. Well, mine is 15ms. And Anroid accepts it in the first place and it suddenly breaks the connection.
