The problem you describe is probably due to the daemon not finding an appropriate BT controller to attach to. 
This led to the "Attach" failing after the "Create", and then none of the commands to the node are able to be
sent.


There are a couple of options here:

1. If you have a single BT Controller (v4 or newer) you will need to disable the main bluetooth daemon so that
the bluetooth-meshd daemon has access to it:
$ sudo systemctl disable bluetooth
$ sudo systemctl stop bluetooth

2. If you have *multiple* BT controllers, make sure the bluetooth daemon hasn't automatically claimed them all:
In /etc/bluetooth/main.conf, make sure AutoEnable=false (reboot may then be required)


In the future, we will be doing work to enable co-existance and controller sharing for single controller
systems. However, this will require some changes in the kernel.
