Hello, Connection between linux router and NRf51 devices worked before I've updated kernel version from 4.09 to 4.3. Now, with the same configuration and hardware, I'm not able to create a link:
root@ap-3:/home/pi# hcitool lesson
LE Scan ...
00:34:3E:DF:03:90 COAP_Client
00:34:3E:DF:03:90 (unknown)
root@ap-3:/home/pi# echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable
root@ap-3:/home/pi# cat /sys/kernel/debug/bluetooth/6lowpan_enable
1
root@ap-3:/home/pi# echo "connect 00:34:3E:DF:03:90 2" > /sys/kernel/debug/bluetooth/6lowpan_control
bash: echo: write error: Connection refused
Does anyone know what could cause the problem, or/and how to solve it? Maybe in new kernel there is some other way of using debug interface for bluetooth 6lowpan? I can't find anything.
Thank you in advance, Michal
