h2. Projects and/or hardware that can be used to do functional testing

h3. Lava

"Lava":https://www.linaro.org/engineering/projects/lava/ can be used to do functional tests on real hardware. It can be easily installed on PureOS, an FSDG compliant GNU/Linux distribution.

h3. OsmoGSMTester

The "OsmoGSMTester project":https://osmocom.org/projects/osmo-gsm-tester is able to be interfaced with the Android RIL through ofono and can emulate a GSM network with the help of a compatible GSM base station or SDR.

This "presentation from 2019":https://media.ccc.de/v/osmodevcon2019-119-osmo-gsm-tester-e-gprs-test-setup has many insights on what kind of issue we might expect in interfacing it with smartphones.

h3. Simtrace2

The "Simtrace 2 project":https://osmocom.org/projects/simtrace2/wiki can be used, along with SIM card readers to programmatically feed a SIM card to a smartphone. This can be used to run test on real networks.

h2. Replicant supported devices and testing

h3. Requirements

* Antenna connector for the modem

* The ability to control the device buttons in order to be able to programmatically power on and off the device, and trigger boots into the bootloader and recovery

* Optionally a way to connect to the serial port, programmatically

h3. Galaxy S2 (I9100)

* The Galaxy S2 (I9100) has:

** An antenna connector

** The SOC serial port that is accessible behind the USB connector at a low voltage

** A full size mini-sim (easier to interface with)

Holding the smartphone in place:

* The smartphone could either be screwed on a metallic surface or an external case could be screwed on a metallic surface enabling the smartphone not to move.

SIM cards:

* Simtrace 2 "lacks screw holes":https://osmocom.org/issues/3711 so a way must be found to make sure that it doesn't move as it uses flex cables to interface with the SIM socket of the smartphone. That may be fixed in a subsequent hardware revision.

Serial port and USB:

Buttons:

Battery:

Antenna connector and GSM tower or SDR:

The Galaxy S2 (I9100) has two antenna connectors:

* One internal connector, TODO: find the connector type

* One external connector, TODO: Find the connector type

h4. Example setup

See also the links inside the [[Serial_port]] article for more background on how to get serial port access on devices like the Galaxy SIII (i9300) or the Galaxy S2 (i9100).
