I am having problems communication with PPK2 using pySerial library. Below is an example of code causing the error. When I try to request metadata twice during the same connection PPK ignores the second one and returns nothing. Is this intended? Is there a workaround?
import serial
if __name__ == '__main__':
ser = serial.Serial("COM4", baudrate=115200)
ser.write(b"\x19") #\x0A\x0D
r=ser.readline()
print(r)
while not str(r) == "b'END\\n'":
r=ser.readline()
print(r)
time.sleep(1)
ser.write(b"\x19")
print("response")
r = ser.readline()
print(r)
while not str(r) == "b'END\\n'":
r = ser.readline()
print(r)
ser.close()
