[lwip-users] Wireless Errors

[Zahir Lalani]

Hi All

 

Wondering if you can point me in the right direction.

 

I have written a custom protocol to send data between a desktop app and our embedded system which uses lwIP. In recent weeks I have played around with the opts settings based on what I have read-up and have got the throughput working much better. When I am on a wired network – I don’t see any errors and the system works great.

 

Using the same code with my laptop on a wireless connection, it is expectedly slower, but I also get more errors where the desktop app never gets an ack (from the server application) and has to retry. Sometimes the errors cause the server end to completely lock up, and pings don’t even respond. I know it’s a really open question, but I am no expert on tcp and need to know where to look for issues.

 

TIA
