4. MySignals Software Installation
All programs that you can use with MySignals can be found on:
www.libelium.com/development/mysignals/sdk_and_applications
4.1. MySignals Updater Tool
MySignals Updater Tool is the ocial rmware download tool developed by Libelium.
Step-by-step instructions for setting up the MySignals Updater Tool on your computer and connecting it to MySignals devices.
Start by visiting Libelium website and selecting the Mac, Windows, or Linux version, depending on what machine you have.
Installation on each machine is straightforward:
• On Windows, you’ll have a .zip le. Double-click it, and drag the folder inside to a location on your hard disk. It could be
Program Files or simply the desktop, but the important thing is for the processing folder to be pulled out of that .zip le.
Then double-click Mysignals_Updater.exe to start.
• The Mac OS X version is also a .zip le. Double-click it and drag the MySignals Updater Tool icon to the Applications folder.
If you’re using someone else’s machine and can’t modify the Applications folder, just drag the application to the desktop.
Then double-click the MySignals Updater Tool icon to start.
• The Linux version is a .tar.gz le, which should be familiar to most Linux users. Download the le to your home directory,
then open a terminal window, and type: tar xvfz Mysignals_Updater-xxxx.tgz
It is important to use the version found on Libelium website and no other version. This is because the version available on the
Libelium website has been properly tested and for which we can assure optimum operation.

4.2. MySignal Web Server Application
Telemedicine is the use of telecommunication and information technologies in order to provide clinical health care at a distance.
It helps eliminate distance barriers and can improve access to services that would often not be consistently available in distant
rural communities. It is also used to save lives in critical care and emergency situations.
MySignals allows to share data with the cloud, and perform real-time analysis. Thanks to many communications modules can
send data over several transmission protocols.
MySignalsWeb ServerApplication is areal-timelarge-datasetviewing andplottingtool and hasbuilt-indata analysis functionality.
It is very user-friendly and contains many powerful built-in features. MySignal Web Server Application is an application that

5. Accessing MySignals Data
MySignals works in several models, we have to think about a person who does not have a mobile phone and this person does
not have internet connectivity, the simplest case, then let’s explain each mode:
Standalone mode: MySignals does not send data to a mobile phone or cloud (no connectivity at all), there is only a single
(or many) MySignals device isolated. With this mode the MySignals device will store data for a period of time and it cannot be
sended to nowhere.
Standalone + connectivity (WiFi): MySignals is not paired with a mobile phone but it has internet connection. MySignals
device will store data in its system and then it will send data to libelium’s cloud service.
BLE mode: MySignals + mobile phone. MySignals device will send data to mobile phone and it will feed MySignals application,
this way the mobile phone will update data to Libelium’s cloud, then the mobile phone will be able to store all data into a local
database to cover situations where the phone does not have connectivity.
MySignals device will send data to application using two modes:
In Datagram mode the MySignals device will send all values for all sensors, this is used for main sensors screen where we show
a list of selected sensors by the user with its values.
Regarding to Detail mode, it is used when the application shows a detailed view from sensor, MySignals will only send data for
this single selected sensor. The application will send a sign to MySignals to switch on and o this mode.
When the MySignals device establish a pairing with the application it send information in Datagram mode by default. Let’s show
a little graph to understand each mode:

5.1. MySignals Standalone Screen
The sensor measures are distributed in dierent screens that change by pressing in the Screen.
In the rst screen you can congure the operating mode: BLE, WIFI or standalone.
Figure : MySignals conguration screen
In bluetooth mode you can congure the connection and then MySignals APP will start to receive data from MySignals.
Figure : Bluetooth mode conguration screen
In standalone or WiFi mode you can select the sensor that you want to monitor and MySignals will start to monitor all the
parameters.
Figure : MySignals Data monitoring screens

-15-
There are several basic conguration screens: language, prole, user…
Figure : MySignals basic conguration screen
5.2. MySignals Web Server Application
MySignals application will have an user account to login into the system, this account is important to make cloud call and store
information. If the user does not have an account the user cannot use MySignals application.
Each account will be able to have one or more proles, let’s think about a doctor that has many users, each user is a prole.
Each prole should be synchronized with cloud to be up-to-date with user information.
When the user start the MySignals application for the rst time and setup assistant prompts the user will be able to create a
prole once the user logs in.
MySignals must have a credentials screen where it show which user is logged in into our system and this screen will be able to
log out the user and ask again for credentials in order to keep using the application.
To congure MySignals application for each device, we will need to set common parameters.
You can see all the data of each device or user in the User Data section.
Figure : User Data MySignals Web

-16-
Using the Department, User or Device conguration sections you can create, congure or delete them.

-18-
How do I ensure the privacy of the biometric data sent?
Privacy is one of the key points in this kind of applications. For this reason the platform includes several security levels:
• In the communication link layer: WPA2 for Wi.
• In the application layer: by using the HTTPS (secure) protocol we ensure a point to point security tunnel between each
sensor node and the web server (this is the same method as used in the bank transfers).
5.3. MySignals Mobile APP
The Bluetooth connectivity may perform direct communications with iPhone and Android devices without the need of an
intermediate router.
The rst time a user starts MySignals application, it will be needed a setup assistant to congure all aspects related to MySignals
conguration like user name, password (already set in our back end), prole, WiFi settings and MySignals selection. We will
create a setup assistant with straightforward screens with all eld and information to guide the user through this assistant.
Design department had provided some sketches with an idea about how assistant can be done, these images represent each
step in our assistant:
Figure : MySignals APP conguration screen
An account can have one or more MySignals devices, this is why an user can purchase more than one device. Then we must
create am MySignals manager to provide a list of devices and perform some basic operation over them.
This manager can add/delete/modify/select an MySignals device. This information should be synchronized with cloud to get all
devices up to date for a given account.
As each MySignals is tied to each single user, we should download a list of devices each time an user log in, this way we do not
mix MySignalss from dierent accounts.
In the rst screen you can congure the operating mode: BLE, WIFI or standalone.

-19-
Then you can select the sensor that you want to monitor and MySignals will start to monitor all the parameters.
Figure : MySignals APP Data monitoring screens
There are several basic conguration screens: language, prole, user…
