EspruinoHub Issues

Hi all,

I've now setup a rpi3 with EspruinoHub. Instead of using the minimal raspbian image as before, I chose the full image and pretty much followed all instructions. Instead of installing node the way it is described in the tutorial, I went with the node version mananger, which worked very nicely. Now the issues:

• if there is no puck in reach or no ble devices, the hub will stop after a few seconds. What is the reason for this? I can well imagine that sometimes no devices are in reach, I would want the hub to stay active all the time and wait for a device to appear.
  

• I've used the sample code given in the tutorial, but I get some issues:

  NRF.requestDevice({ filters: [{ services: ['1823'] }] }).then(function(device) {
  require("ble_http").httpRequest(device, "pur3.co.uk/hello.txt", function(d) {
  print("GET:",JSON.stringify(d));
  });
  });
  

Once I connect to my (whitelisted) puck and upload the code with the Espruino IDE, I get this:

In the EspruinoHub console, I see that a device connected, but after this short intermezzo and no other significant error message (almost nothing, I see that my puck got scanned and it's RSSI), the hub then also terminates. Any idea?
