using wiith Rasberry PI 3 no response

Hi i have hooked up the scanner correctly to my GPIO board and when i try run raspberry_pi_GPIO_test.py all i get is Command:open then

Traceback (most recent call last): File "/home/pi/Desktop/pyGT511C3-master/raspberry_pi_GPIO_test.py", line 32, in
fps = FPS.FPS_GT511C3(device_name='/dev/ttyAMA0',baud=9600,timeout=5,is_com=False)
File "/home/pi/Desktop/pyGT511C3-master/FPS.py", line 319, in init
self.Open()
File "/home/pi/Desktop/pyGT511C3-master/FPS.py", line 333, in Open
self.SendCommand(packetbytes, 12)
File "/home/pi/Desktop/pyGT511C3-master/FPS.py", line 756, in SendCommand
self._serial.write(bytes(cmd))
File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 475, in write
n = os.write(self.fd, d)
KeyboardInterrupt when i inturupt to quit out

if i try to run baud_to_115200.py i get the following:

Traceback (most recent call last):
File "/home/pi/Desktop/pyGT511C3-master/baud_to_115200.py", line 16, in
fps = FPS.FPS_GT511C3()
File "/home/pi/Desktop/pyGT511C3-master/FPS.py", line 316, in init
self._serial = connect(device_name,baud,timeout,is_com=is_com)
File "/home/pi/Desktop/pyGT511C3-master/FPS.py", line 277, in connect
device_name = DEVICE_NAME
UnboundLocalError: local variable 'DEVICE_NAME' referenced before assignment

Can anyone advise? I'm just getting into PI's and i don't have a firm understanding. Thanks

I have the same problem! any solution?

replace FPS.py in your code with file named FPS2.py. https://github.com/Jucker/SIPIntercom-with-FPS .This is guy modified the file to work with code. if you face any problem try to change the baud rate 2-3 time

Hi folks,
This driver has a paid support via Skype. You just need to donate USD 100 on the link bellow once, and you will get all the online support needed to make your implementation works fine:

Anyone found the solution ? I have the same problem

For me the problem is solved. The serial port should be enabled for connecting devices .By default it is used for bluetooth.

@himanshu-hearthacker Man, even after changing baud rates, I'm getting
"incomplete response in buffer".
Please, Help.
