HVAC bindings and client application for Application Framework Binder

(Application Framework Binder can be found on https://gerrit.automotivelinux.org/gerrit/#/admin/projects/src/app-framework-binder)

Installation

Download and install IoT.bzh docker image and sdk.

1. Follow [this guide](http://iot.bzh/download/public/2016/sdk/AGL-Devkit-Image-and-SDK-for-porter.pdf)
   to get your docker ready and running.

2. Check out this repository
   git clone https://gerrit.automotivelinux.org/gerrit/src/hvacplugin -c b sandbox/claneys/hvac-bindings

Build project

Get into build directory under hvacplugin repo and build the widget:

- cd hvacplugin/build

- cmake .. && make

It will build the binding with QML Frontend and package all that into a wgt file named : hvac-demo.wgt

Install and test the widget

Installation

Transfer the wgt file on your platform with scp :

     $ scp hvac-demo.wgt root@<your_porter_board>:/tmp

than install it using afm-util:

    # afm-util install /tmp/hvac-demo.wgt
    { "added": "hvac-demo@0.1" }

Test

You can launch bindings using the afb-daemon, starting them manually like this, don't forget to change and by your choice using an unused port and a random number for the security token:

# /usr/bin/afb-daemon --ldpaths=/usr/lib/afb:/usr/share/afm/applications/hvac-demo/0.1/lib --mode=local --alias=/icons:/usr/share/afm/icons --port=<chosen_port> --rootdir=/usr/share/afm/applications/hvac-demo/0.1 --roothttp=htdocs --token=<chosen_token> --sessiondir=/home/root/app-data/hvac-demo/.afb-daemon &

With bindings launched you can now test them using afb-client-demo as you have to communicate with bindings using WebSocket protocol. When connection established you can dialog with binding using api/verbs from application framework and running bindings. At first, try to authenticate with auth connect which will renew token and create a new session context for the running app.

Then test following verbs using api hvac:

- ping : Ping the binder
- get_temp_left_zone : Get the left zone temperature
- get_temp_right_zone : Get the right zone temperature
- get_fanspeed : Read fan speed
- get : Read all values
- set : Set value(s)

# afb-client-demo ws://localhost:<chosen_port>/api?token=<chosen_token>

TODO: QML files aren't modified to fit with bindings for now. They have to be modified to make hybrid application works.
