Hi,
I am implementing ContikiOS on my custom nRF52823 board. I have been following the instruction here: github.com/.../README-BLE-6LoWPAN.md
I am running Debian 9 testing. I modified the header file pca10040.h to use different pins for LEDs.
Everying is going well but at the last step, i can't ping the device. I can scan it using hcitool lescan and connect to the device using echo "connect 00:E1:F8:BE:70:DA 1" > /sys/kernel/debug/bluetooth/6lowpan_control. Here is the result of ifconfig
root@myDeb:/home/elecfist# ifconfig
bt0: flags=4161<UP,RUNNING,MULTICAST> mtu 1280

The bt0 interface is also present and up. The leds also indicate that i have connected to be board. The command ping6 -I bt0 fe80::2e1:f8ff:febe:70da returns something like this.
root@myDeb:/home/elecfist# ping6 -I bt0 fe80::2e1:f8ff:febe:70da

How do I troubleshoot this problem?
