However, while connecting the device it gives error "no route to host"

I guess your adapter is not powered, try bluetoothctl> power on

Any idea what is missing here?

$ sudo hcitool -i hci1 lecc 00:60:37:00:00:16
Connection handle 32

Whereas this works fine when I test zephyr IPSP sample (BLE host) with
virtual BLE controller connected to QEMU serial line.

ifconfig shows bt0 up after connecting the virtual device

# echo "connect 00:aa:01:00:00:23 1" >

# cat /sys/kernel/debug/bluetooth/6lowpan_enable

# cat /sys/kernel/debug/bluetooth/6lowpan_control
00:aa:01:00:00:23 (type 1)
