A way to bridge MQTT topics to BLE Gatt characteristics 

run:

    node index.js -c config.js

Where config.js looks like this:

    module.exports = {

      broker: "mqtt://localhost",

      topic: "some/topic"

Background

-----------

There is a blog post that describes how I built this code here:

http://www.hardill.me.uk/wordpress/2015/07/28/building-bluetooth-le-devices/

And another post about building a simple Android App to work with it here:

Known issues

You have to be careful that the payload fits in the MTU

#### Running without root/sudo

Run the following command in the directory you ran ```npm install``` from:

```sh

find -path '*bleno*Release/hci-ble' -exec sudo setcap cap_net_raw+eip '{}' \;

```

This grants bleno's ```hci-ble``` binary ```cap_net_raw``` privileges, so it can start/stop BLE advertising.

__Note:__ The above command requires ```setcap``` to be installed, it can be installed using the following:

 * apt: ```sudo apt-get install libcap2-bin```

 * yum: ```su -c \'yum install libcap2-bin\'```
