Serval Mesh README

Serval Project, March 2014

Serval Mesh (also called “Batphone”) is an app for Android 2.2 “Froyo” and above. It provides free, secure phone-to-phone voice calling, SMS and file sharing over Wi-Fi, without the need for a SIM card or a commercial mobile telephone carrier. In other words, it lets your Android phone communicate with other Android phones running Serval Mesh within Wi-Fi range.

The latest release of Serval Mesh is available for download on Google Play.

Serval Mesh is free software produced by the Serval Project. The Java/XML source code of Serval Mesh is licensed to the public under the GNU General Public License version 3. The serval-dna component of Serval Mesh is licensed to the public under the GNU General Public License version 2. All technical documentation is licensed to the public under the Creative Commons Attribution 4.0 International license.

All source code and technical documentation is freely available from the Serval Project's batphone and serval-dna Git repositories on GitHub.

Warnings

Serval Mesh is EXPERIMENTAL SOFTWARE. It has not yet reached version 1.0, and is intended for pre-production, demonstration purposes only. It may not work as advertised, it may lose or alter messages and files that it carries, it may consume a lot of space, speed and battery, and it may crash unexpectedly.

The Serval Mesh "Connect" screen allows you to connect to other Serval Mesh devices that provide their own access points. If you do so, this will cut off normal Wi-Fi network access while Serval Mesh is running, and services like Google Updates, E-mail, social media and other notifications may not work, or if you have a mobile data plan, may cost you money.

On the Serval Mesh "Connect" screen, connecting to any network marked "HotSpot" will put your device's Wi-Fi into Access Point mode. This will give nearby devices access to your mobile data plan, and COULD COST YOU MONEY.

On the Serval Mesh "Connect" screen, connecting to any network marked "Mesh" will request root permission (super-user) on your Android device in order to put Wi-Fi into [Ad-Hoc mode][]. If you grant super-user permission to Serval Mesh, this will cut off normal Wi-Fi network access while Serval Mesh is running, and services like Google Updates, E-mail, social media and other notifications may not work, or if you have a mobile data plan, may cost you money.

Serval Mesh telephony is a “best effort” service, primarily intended for when conventional telephony is not possible or cost effective, and MUST NOT BE RELIED UPON for emergencies in place of carrier-grade communications systems. The Serval Project cannot be held responsible for any performance or non-performance of the technologies that they provide in good will, and if you use these technologies you must agree to indemnify the Serval Project from any such claims.

The Serval Mesh software copies all files shared using the Rhizome file distribution service to other phones and devices running the Serval Mesh software, regardless of size, content or intended recipient. The Serval Project cannot be held responsible for the legality or propriety of any files received via Rhizome, nor for any loss, damage or offence caused by the transmission or receipt of any content via Rhizome.
