No It looks like if data exchange doesn't take place a connection will be lost maybe due to power save state. Maybe I said something silly.

But when I use hcidump connection is stable. The question is how do autoreconnection implement?

In any case it is possible that problem in my HW but connection may lost due to many reasons. I would like somethink like bonding. If I connect to device as hcitool lecc <bdaddr> I see "BLE link established, IPv6 interface down".

Only echo "connect 00:AA:BB:XX:YY:ZZ 1" > /sys/kernel/debug/bluetooth/6lowpan_control works.

So is it possible to make 6lowPAN bonding or pairing not only connection to quickly reconnect?

We have seen some similar behavior here when we are using the hcitool. It seems like there's a small bug or issue with 6lowPAN and Raspian for doing scanning while in a connected state. At least what we have seen occasionally and reported that if you are in a connection and does a hciscan, the Raspberry sometimes lock up. Is it possible that you are doing something similar?

If we avoid doing scans once you are connected, it seems to be more stable.
