Hi all,

When I use kernel 4.1.6 to test BT 6lowpan, the error of "SMP security requested but not available" is shown.

1. I use bluetoothctl power on

2. echo 1 > 6lowpan_enable

3. echo "connect 00:XX:XX:XX:XX:XX:XX 1" > 6lowpan_control.

Then "SMP security requested but not available".

I test kernel 4.1.3 and BT 6lowpan works well.

Any suggestion? Thanks.

Best Regards
Zheng Wu
