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.
