OMAP Wireless Connectivity Battleship Game demo

Purpose

The Battleship Game demonstrates WiFi-Direct capability.
The WiFi-Direct technology is used in order to search for other players and to establish wireless connections in ad-hoc style.

How to Play

Battleship is a well-known 2 player game where the objective is to sink all of your enemy ships.
On the start of the game players set up the positions for each of their ships, and then they take turns guessing squares on their opponent's grid and seeing if those squares are occupied (a 'hit') or not (a 'miss').
The first player to destroy all of his opponents ships wins the game.

Playing the Game

Setting the MAC Address

To work properly, each EVM must have a unique MAC address. Refer to the OMAP_Wireless_Connectivity_Station_MAC_Change for instructions.

Configuring Device Name

First thing we want to do is to configure the device name for the Wi-Fi direct.
For this, you need to choose the "WiFi Direct" Icon as shown below in the second row at the right:


Figure 1 - WiFi Direct Icon

On the WiFi-Direct main screen, check the top-left check-box called "Enable WiFi Direct". Then, click on "Settings" button as shown below:

Tap on the "Device Name" editor and a virtual screen will appear so you can type the desired device name:

Once you choose the name, click on the "Save" button, followed by "Back" button, then, click "Exit" to quit the WiFi-Direct application.
Now, the device name is configured and we are ready to play the game.

NOTE that if you don't do this step, your device name will be set to default value which is the machine type, for example, "am37x-evm".

Starting Battleship Game

To start the Battleship game, tap on the icon called "Battleship" shown below:

Here, you have two choices:

1. Host the battelship game
2. Connect to a game (hosted by another EVM)

Hosting Game

If you choose the option "Host Game", the EVM will be the server and wait for other EVM to connect to it.
When choosing this option, this is the screen you get:

Connecting Game

If you choose the second option, which is called "Connect to Game" you will have a dialog window where you can choose the EVM you want to connect to:
