ECG AD8232 User Manual

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)
