Dear all, I am doing a project about receiving ecg signal from a ecg sensor. At first I am successfully connect the ecg sensor with a bluetooth transmitter using arduino and connect a bluetooth dongle to my PC using USB port. I use processing to write a program in pc to receive the data from arduino which output the ecg signal through bluetooth, and the received data in my PC is what I expected.
However, when I tried to write a android app to receive the bluetooth data, I found that there is some data loss, and the received is not the same as what I received in my PC. Why is that? Is there any differences between android bluetooth and bluetooth dongle in PC? I have found that if I use android to receive the ecg data through bluetooth, the android will receive several ecg data in one packet, but it is not the case if I use PC to receive the bluetooth data. My devices: 1) Arduino + ecg sensor + bluetooth transmitter. 2) PC + bluetooth dongle (connected using USB port) 3) Android 1) + 2) can produce what I want, but 1) + 3) cannot. Therefore, I wonder why android receive bluetooth differently from PC with bluetooth dongle.
