Part of the Arduino function is as follows： void sendDataThroughUART(void){ DataPacket[0] = ecgFilterout; DataPacket[1] = ecgFilterout >> 8; DataPacket[2] = resWaveBuff; DataPacket[3] = resWaveBuff >> 8; DataPacket[4] = globalRespirationRate; DataPacket[5] = globalRespirationRate >> 8…

The redundant delay added during my Bluetooth transmission caused data transmission problems. Thanks for your answer, I solved my problem! :flushed:

I can receive data but the waveform drawn is not ECG

And the data receiving speed is much slower than the serial port output.
