Android Question Network debugging

[Tom81]

I have a classroom of about 20 students. Most of them have problems connecting with B4A-Bridge. It keeps connecting and disconnecting, continuously.
I modified B4A-Bridget to show last error when it disconnects. (https://www.b4x.com/android/forum/threads/b4a-bridge-improvement.166287/)

It seems that disconnecting is caused from a regular disconnect request, because I have:
- Connected ...
- Disconnected ...
- Connected ...
- Disconnected ...
- Connected ...
- Disconnected ...

without any error.
In some PC I solved the problem disabling the Firewall. In other PC/Phone there is some other porblem.

How I could debug the network data stream to understand what happens?

Thank you

It looks like two or more IDEs are trying to connect to the same ip address. This will make the device iterate between the IDEs. They can be running on the same computer or on different computers.

Already checked, this isn't the case.

Is it possible to see any single byte of data stream ?
So to understand what happens ?

You can use wireshark or a similar sniffing tool.
