For this project as you explained. I would use bluetooth - but there is always pros and cons:

Bluetooth Pros:

<ul>
<li>Super easy to implement.</li>
<li>Literary simulates the serial port, sends the string and interprets it.</li>
</ul>

Bluetooth Cons:

<ul>
<li>Not as reliable as Wifi.</li>
<li>Not all devices have bluetooth. But almost every tablet/phone has Wifi.</li>
<li>If not used properly, you can jam up the socket and need to reconnect.</li>
<li>One bluetooth server can feed up to 7 devices. Wifi direct (AS FAR AS I KNOW) has no limitation on the number of connections (But it slows down after 5 connections or so)</li>
</ul>

<hr>

Having said all this, I am not sure what is the role of server in your application. If the project is as you drawn, I would only use the two tablets and get rid of the middle man (the phone)... Unless, there are other reasons behind it.

<hr>

A very easy to understand Bluetooth implementation <a href="https://android.googlesource.com/platform/development/+/eclair-passion-release/samples/BluetoothChat" rel="nofollow">example</a>.

It depends on the amount of bandwidth that is required by the particular game. In most cases, Bluetooth will be perfectly fine. It has the advantage of having a lower power requirement. If you are streaming audio or video data, go for WiFi.

XMPP is unnecessarily complex for a game. Have you looked at <a href="https://google.github.io/flatbuffers/" rel="nofollow">FlatBuffers</a>?

blocks|key|1420873|text|如果你想在手机上播放游戏，Wi+P2P是最好的，但我从这个页面上得到的东西，它可以在Android4.0和更高版本上使用。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1420874|使用这些API，当每个设备都支持Wi+P2P时，您可以发现并连接到其他设备，然后通过比蓝牙连接更长的距离进行快速连接。这对于在用户之间共享数据的应用程序非常有用，例如多人游戏或照片共享应用程序。|blockquote|1420875|如果你想用字符串监视游戏，你最好使用蓝牙。我不知道大约10米，但我相信蓝牙工作在不到10米。|1420876|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/guide/topics/connectivity/wifip2p.html^0|T|2|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]]|C|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|C|$]]|$1|G|3|H|5|6|7|V|8|@]|9|@]|C|$]]|$1|I|3|-4|5|6|7|W|8|@]|9|@]|C|$]]]|J|$K|$5|L|M|N|C|$O|P]]]]

If you want to stream the game on the phone Wi-fi P2P is the best but what I got from this <a href="http://developer.android.com/guide/topics/connectivity/wifip2p.html" rel="nofollow">page</a> it's available for android 4.0 and later.

<blockquote>
 Using these APIs, you can discover and connect to other devices when
 each device supports Wi-Fi P2P, then communicate over a speedy
 connection across distances much longer than a Bluetooth connection.
 This is useful for applications that share data among users, such as a
 multiplayer game or a photo sharing application.
</blockquote>

If you want to monitor the game with strings you'd better use Bluetooth. I don't know about 10 meters but I'm sure Bluetooth works fine in less than 10 meters.

The plateform is Android 4.+

<ul>
<li>I have 1 phone playing the role of server and 2 tablets as clients</li>
<li>The tablets are at a distance &lt; 5-10m from the server, in the same room</li>
<li>My goal is to have the phone launch a game between the two tablets, and monitor what is going on (like a game master)</li>
<li>There will be many exchange of data from/to the phone which command a robot by bluetooth (already paired and managed by an independent app and SDK, i don't have the sources of that part)</li>
</ul>

For the communication protocole I'm thinking of using <a href="http://xmpp.org/" rel="nofollow noreferrer">XMPP</a> which appear to be nice. 

For the "how" I can't decide which one is best between these two: 

<ul>
<li><a href="http://developer.android.com/guide/topics/connectivity/bluetooth.html" rel="nofollow noreferrer">Bluetooth</a></li>
</ul>

OR

<ul>
<li><a href="http://developer.android.com/training/connect-devices-wirelessly/wifi-direct.html" rel="nofollow noreferrer">Wi-Fi P2P</a></li>
</ul>

Which one should i use in this case ?

Most efficient way to communicate between 1 phone and 2 tablets at close distance?
