Hi Sanghee,

have you installed `bluerobotics-ping` with pip3 ?

Hi,  
I am facing an issue with the simplePingExample.py.  
Opening /dev/ttyUSB0 at 115200 bps  
Traceback (most recent call last):  
File “/home/i4mt/ping-python/brping/device.py”, line 50, in connect\_serial  
self.iodev.send\_break()  
File “/usr/lib/python3/dist-packages/serial/serialposix.py”, line 701, in send\_break  
termios.tcsendbreak(self.fd, int(duration / 0.25))  
termios.error: (32, ‘Broken pipe’)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):  
File “/home/i4mt/ping-python/echo.py”, line 4, in   
myPing.connect\_serial(“/dev/ttyUSB0”, 115200)  
File “/home/i4mt/ping-python/brping/device.py”, line 55, in connect\_serial  
raise Exception(“Failed to open the given serial port: {0}”.format(exception))  
Exception: Failed to open the given serial port: (32, ‘Broken pipe’)

This is the error i get while running the code. I am running the code on raspberrypi 5 with raspbian os. The echosounder is working well because i have checked it using the ping-viewer. But on linux, it is not even opening the port. I enabled the Serial port permission on sudo raspi-config, added user permission for /dev/ttyUSB0, tried using raspberrypi 4, tried in a ubuntu system, tried using screen for monitoring the serial data but came out as a blank screen. Same problem persists.  
please help!
