Hi Group,
I am trying to establish a 6LowPAN over BLE connection between my
Ubuntu Laptop and Raspberry Pi 4B. Laptop is running Ubuntu
5.8.0-48-generic #54~20.04.1-Ubuntu and my RPi is running custom
yocto-based Linux distro with kernel version 5.4.x version.
I am facing an error of 0x12 when trying to establish to Rpi from the
laptop as below:
root@root1-Nitro-AN515-55:/home/root1# lsmod | grep 6low
bluetooth_6lowpan 28672 0
6lowpan 40960 8

root@root1-Nitro-AN515-55:/home/root1# echo 1 >

root@root1-Nitro-AN515-55:/home/root1# dmesg
root@root1-Nitro-AN515-55:/home/root1# echo "connect DC:A6:32:F2:CB:46

root@root1-Nitro-AN515-55:/home/root1# dmesg
[239155.542994] Bluetooth: hci0: request failed to create LE
connection: status 0x12
Running btmon in another shell resulted in the following log as attached.
Additional Info: using bluetoothctl between my Laptop and RPi s
successful but 6LowPAN is unable to go through.
Any missing from my end?
Thanks,
Nagesh.
