"SMP security requested but not available" when BT_6lowpan connection

"SMP security requested but not available" when BT_6lowpan connection

[Zheng, Wu]

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

can try to boot a bluetooth-next kernel and see if the error is still present. We included a fix for the warning.

Hi Marcel,

6lowpan over BT LE works well in the bluetooth-next kernel.

The key patch is Johan's 0dd5c7aa199b25a88e9fa72824abaf0020ec8066.

For fixing the related bug in yocto project, I have submitted the patch to linux-yocto upstream.

Thanks.

Best Regards
Zheng Wu
