Hii everyone!! I am doing a project in which i have to plot a graph from the data obtained from the arduino.I am saving the data obtained in a.csv file.Is there any way to transfer this .csv file from arduino sd card to an android device using bluetooth module?
Read the file byte by byte and send the bytes to the Android device.
The DumpFile example included in the IDE is all you need. You might also find the following background notes useful
