There are multiple thins going on here: - Currently bluetoothd & bluetooth-meshd cannot run on the same controller (addressing this requires kernel changes). So if there is only one controller it's either bluetoothd or meshd daemons, but not both. Please check if bluetoothd is running. Perhaps, with systemctl meshd starts before bluetoothd starts and grabs the single hci device? - mesh-cfgclient needs to have an additional check for Network1 being detected. This would deal with the symptom not the reason. - I believe the daemon should be fixed so that d-bus service is not exposed unless there is a BT controller available. Will look into this.
