Hi all,
i have following issue, i can control wheels and servo for the pi camera, lights, but status info like cpu and ram usage are not showing in the client application:

when i execute the server script on raspberry, and connect with the client app, i see this error messages:

please any ideas how to fix this? also the video window is not showing from the application.

thx for any hints.

It's not connecting. Either the server isn't running correctly, isn't running at the IP address you have tried, or there is a firewall blocking the connection.

@1580791099 - as you can see in the 2nd screenshot, im connected to the correct IP.

so the server.py doesnt open the ports for stats and ultrasonic:

as is in the code written:
def Info_receive():
    global CPU_TEP,CPU_USE,RAM_USE
    HOST = ''
    INFO_PORT = 2256  

def ultra_receive():
    global ultra_data, canvas_text, canvas_rec
    ultra_HOST = ''
    ultra_PORT = 2257

Add time.sleep (0.5) above line 102 of serve.py to let the child thread run completely before connecting to the GUI. If you are not convenient to change the code, we will update the code to github later, then you can clone it again.

@ Adeept - thx for reply... i added the time.sleep value. but there are more bugs in the code:


still the status windows are not displaying anything...

EDIT: im going trough the code and apparently the client.py is acting as a server script and listening on port, when it should connect to remote port:


and the server.py is trying connect to itself and not listening on the opened ports:

@ Adeept - thx for reply... i added the time.sleep value. but there are more bugs in the code:

Add time.sleep before ultra_Socket.connect (ultra_ADDR) (refer to the picture location). We've tried to connect more than ten times after adding these two time.sleep, and no problem occurred each time. If your problem still exist, you can also delay time.sleep for a longer time so that the ultra and info threads have more time to start.

@ Adeept - issue still persist...

Hi,

I am facing the same issue. Can you give me the fixed code? I tried to git pull latest code from adeept_awr repo with no luck!
