Serial Receiving from Arduino to Raspberry Pi with PySerial stops after a while

Question

I\'m working on a project in which I have to receive some 25 character data at a time in order to process it in Raspberry Pi. Here is the example code that generates some da

Answer 1

During your loop function in your Arduino code you never end an newline char \n, this is only a problem with ser.readline() because it reads until a \n character.

During your setup function you correctly send a \n character which could explain the intial value being sent, but not the data.

perhaps modifying your Arduino code like this:

void loop(){
    for(i=0;i<25;i++){
        for(a=0;a

And your python code like so...

ser = None
try:
    ser = serial.Serial('/dev/AMA0',9600,timeout=3)
    ser.open()

    while True:
        try:
            serial_data = ser.readline()
            print serial_data
        except:
            pass
except:
    pass    
finally:
    if ser:
        ser.close()
