Merge lp:~cypressyew/checkbox/bt4-HOGP into lp:checkbox

[Po-Hsu Lin]

Add a manifest request for asking tester about BT 4.x capability of this system.
Add a BT 4.x specific test case for HID devices (keyboard / mouse)

[Po-Hsu Lin (cypressyew)]

The reason why we're only adding a new test case for HID is that, this HID Over GATT Profile is a new feature for Bluetooth 4.x devices. For those old profiles like obex, they are not a new stuff, so leave it as-is for back-ward compatibility test.

[Ara Pulido (ara)]

Can we do the test more automated, please?

Things that we can automate: The name of the device may be configurable, enabling bluetooth and selecting the configured BT device should be automated.

Thanks,
Ara.

review: Needs Fixing

[Yung Shen (kaxing)]

About the job naming with 4.x, there is a small quirk between versions: 4.1 is software upgrade but for 4.2 some feature requires hardware upgrade. It might be better to left the x for the future job.

[Yung Shen (kaxing)]

About automation, a note for HOGP devices, at least the two mouses that I've handed on, they will changing MAC address from each pairing reset.

And since this set of bluetooth jobs will be used on Desktop releases, I think the interactive part of testing would be more closer to real-life scenario.

[Ara Pulido (ara)]

We don't want to mimic real-life scenario. We want to be efficient in our testing.

p-p-c: Add BT automated script for mouse, and corresponding test case.

Add BT automated script, which will ask tester to enter MAC address,
Split the BT4 HOGP test cases into 2, mouse and keyboard.
Improve the term "BT 4.x" with "Bluetooth Smart".

4266. By Po-Hsu Lin on 2016-03-16

p-p-c: Convert bt_connect script to python3.

Apply to try statement to convert this script to python3,
add some docstrings and change the todo list

4267. By Po-Hsu Lin on 2016-03-17

Merging Yung's patch to align Bluetooth Smart naming.

Aligning bluetooth 4.x naming

4268. By Po-Hsu Lin on 2016-03-17

Add scanning feature and improve the keyboard test case.

Add scanning feature and class code dictionary to determine which device to connect.
Improve the keyboard test case.

[Po-Hsu Lin (cypressyew)]

Hi Yung, please modify the executable base on Maciej's bt_helper
