turns orange, you can turn off the sensors in any order.

3.2. Control the Physilog from a mobile application

The Gait Up companion mobile applications allow to control the Physilog 6S sensor. There is no

need to pair your Physilog® with the tablet prior to Bluetooth communication, just select the

Physilog® from the list in the app. In order to be able to connect a Physilog 6S to a mobile

application it needs to be visible by Bluetooth. This can be achieved by different methods which

can be set in the configuration of the device, the default setting is activation of the BLE

advertisement for 30 seconds by gently shaking the sensor (see the Research Toolkit user

manual for details).

Physilog 6S provides several modes which can be controlled by the companion mobile

application:

Raw data stream

The raw data stream mode allows to send the raw sensor data (3D acceleration, 3D angular

velocity, barometric pressure and 3D magnetic field) to a mobile device via BLE in quasi

real-time. The Physilog does not save any data on its internal memory in this mode. Depending

on the firmware version, the sensor shines or blinks green during the raw data stream.

Remote controlled recording

The remote controlled recording allows recording data files like in standalone mode, except that

the start and stop of the recording is done via a command from the mobile application instead of

pressing the button on the sensor. One file per recording between a start and stop in the mobile

application is created on the internal memory of each Physilog. No data is streamed to the

mobile application. Depending on the firmware version, the sensor shines or blinks green during

the remote controlled recording.

Remote controlled recording with File transfer

This mode adds the streaming of the recording file from the Physilog to the mobile application to

the remote controlled recording. The Physilog still saves one file per recording on its internal

memory, and in addition it sends this binary file to the mobile application during and at the end

of the recording. Depending on the firmware version, the sensor shines or blinks green during

the file transfer recording.

Troubleshoot: If a sensor is not detected by the tablet, gently shake the sensor or shortly press

the button to enter detection mode (depending on the settings). If the sensor can still not be

connected, check that it has enough battery and is not connected to another mobile device and

if necessary ultimately do a reset of the sensor as explained in section 5.7 Troubleshoot.
