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 &  3665 Can't connect RFCOMM socket: Host is down
Does anyone know how to resolve this issue? Any help would be very much appreciated.
