I'm not sure if anyone have tested OpenWRT with kernel 4.4, but at least it should work with Raspbian Jessie.

Petter, I noticed if you clone the mainline trunk from openwrt, it builds the 4.4 kernel with the latest Bluetooth_6lowpan kernel module which has 6lowpan_enable instead of 6lowpan_psm. I'm not able to establish connection using this version. But if I download the chaos_calmer branch, openwrt is built with 3.18 kernel and older version Bluetooth_6lowpan kernel module and using this version I'm able to establish connection, so ill stick with this for now. Have you guys tried building and test the latest mainline openwrt with 4.4 kernel and the latest Bluetooth_6lowpan kernel module?

I see. Could you try the following:

echo 1 > /sys/kernel/debug/bluetooth_enable

echo 35 > /sys/kernel/debug/bluetooth/6lowpan_psm

Ok. What versions did you use? Are you using Raspberry Pi 1?

Hello Petter, Yeah, i have called exactly how you mentioned. I was actually able to establish proper connection to my nrf52 using raspbian OS. the problem is when i use openwrt image. i built an openwrt image with bluetooth_6lowpan kernel module, bluez libs and utils. as soon as send a command in this format echo "connect 00:AA:BB:XX:YY:ZZ 1" > /sys/kernel/debug/bluetooth/6lowpan_control i get the following error : "write error: Connection refused"

Have you followed this? Are you calling something like echo "connect 00:AA:BB:XX:YY:ZZ 1" > /sys/kernel/debug/bluetooth/6lowpan_control ?
