Write an arduino program to access fingerprint scanner in android mobile app (App is already developed and work with Bluetooth serial communication , your job is to handle only arduino part )
Here is a setup.
HC 05 Bluetooth
R305 fingerprint sensor
Using Bluetooth Arduino will receive command when to read the fingerprint.
Fingerprint module will read the data will send the image data using the same Bluetooth.
Should use only software serial for communication
Use digital pins for communication.
1) Wiring design
2) Arduino code with library
3) setup in my machine if required.
