If all is going well, in the journalctl log you should see something like:
```
Sep 05 07:52:12 frank EspruinoHub[2507]: <Discover> Starting scan...
Sep 05 07:52:12 frank EspruinoHub[2507]: <Discover> Scanning started.
```
If it doesn't (which it isn't in your case) it's probably because node.js doesn't have the right permissions to access Bluetooth LE. Can you try running which node, and if that displays a path, can you run:
```
sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)
```
And see if that helps after you then do sudo systemctl restart EspruinoHub.service to restart EspruinoHub?
