Software Description 

 
No software programming knowledge is required. EcgSmartApp is available only for Android 
(at least Android 6 or higher).

 

 
 

 

Arduino Programming:

 Arduino sketch files can be uploaded on the Arduino board 

easily by installing the Arduino Software IDE (free download from the Arduino official 
web  site)  and  following  the  tutorial  available  on  Arduino  official  web  site.  A  single 
sketch  file  (“ECG_SmartApp_skecht_arduino.ino”)  for  both  Arduino  Nano  and 
Arduino UNO is provided (the sketch was tested with both the boards). The same sketch 
should work also with Arduino Micro (this board was not tested). For other Arduino 
board the sketch file may need changes.

 

 
 

 

Installing  the  ECG  SmartApp:

  To  install  the  App,  copy  the  provided  apk  file 

“ECG_SmartApp.apk” on the smartphone memory, open it and follow the instruction 
by  accepting  the  permissions.  Before  installing,  it  may  be  needed  to  change  the 
smartphone setting by allowing installation of app from unknown sources (tick the box 
of  “Unknown  sources”  option  of  the  “Security”  menu).  To  connect  the  ECG  device 
with the HC-06 (or HC-05) Bluetooth Module, pairing code or password may be asked 
in case of the first Bluetooth connection with the module: enter “1234”. If the App does 
not find the Bluetooth Module, try to pair the smartphone with the HC-06 (or HC-05) 
Bluetooth Module by using the smartphone Bluetooth Setting (pairing code “1234”); 
this operation is needed only once (first connection)
