I have bluez 5.4.3 and I am attempting to communicate with a ble device through minicom. These two deceives (my computer and a bluno nano) are alreadt paired and this has been my method so far.

#bluetoothctl
# pair xx:xx:xx:xx:xx:xx
# exit

Everything is working well so far then...

#sudo rfcomm connect /dev/rfcomm0 xx:xx:xx:xx:xx:xx 1 &
[1] 3665
Can't connect RFCOMM socket: Host is down

Does anyone know how to resolve this issue? Any help would be very much appreciated.

Seems that your local bluetooth hci device is down.

Try hciconfig to get current device name and status, and you can use hciconfig hci0 up where hci0 is your device name.
