 3.1  

Connection to mobile application 

Each time you open the application from completely closed state you need to connect the 
two Physilog

®

5 to the mobile device. Once they are connected you don't need to repeat this 

procedure when switching between different parts of the application.  

To connect Physilog

®

5 to the application for gait analysis, login with your user name (email 

address) and password and enter the “Gait analysis” functions of the app.  Allow Bluetooth 
to be turned on the device and establish a connection to the internet. There is no need to 
pair your Physilog® with the tablet prior to Bluetooth communication.  

C

lick on the “Available Physilogs” refresh button below the picture of 

the Physilog

®

5 on the left of the screen of the application to look for 

available sensors. Chose two Physilog® from the list and click on the 
“Connect”  button  beside  the  sensor  name.  The  name  of  the  sensor 
contains the number which is written on the back of the Physilog®5. 

Troubleshoot:

 If a sensor is not detected by the tablet, shortly press 

the  main  button  of  the  sensor  to  enter  detection  mode.  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 4.4 Troubleshoot. 
If the sensor has incompatible firmware version for using with the app, the app displays an 
error message and automatically disconnects from the sensor. If the sensor is blinking after 
disconnection,  you  need  to  do  a  soft  reset  of  the  sensor  (see  section  4.4  Troubleshoot). 
Physilog5 user manual explains how to update firmware. 

When the sensors are connected the button changes to “Disconnect” 
and  a  green  dot  appears  besides  the  sensor  name.  You  can  see a 
battery level estimation for each sensor below the battery symbol and 
you can check if the sensor is measuring correctly by displaying the 
raw data inside the Signals Visualizer part of the app. 

For  devices  with  small  screen  (such  as  smart  phones),  the  sensor 
connection  screen  is  available  after  clicking  on  the  image  of
