}I made this sauce to implement lwip tcp server
If I try to remove the st-link wire and do it without debugging, the server won't connect
I try to find a way, but I don't know where the problem is
If the LED on the board blinks, it means it's down
Is there a problem with why the server is not working?
If you turn it to debugging, you receive it without any problems, generate a message, and then send it
Then isn't there a problem with the sauce?
I think it's a server problem because the connection itself is not working without debugging
But if it's a circuit problem, I think it's weird to be a server when you debug it
I don't know where to look
If you see that the LED is blinking, the code seems to work normally, but strangely, it is not connected to the client
All the LEDs are working, but the conn n_n netcon = new (NETCONN_TCP); I think there's something in the same part, but if this is a problem, shouldn't it not be debugged?
The test went well by implementing a message response, but if I don't debug it, I can't connect to the client, so I can't get an answer
Not only this, but I also tried to implement a server (source code is different) using bw16 module (wfi module) with stm32, but I couldn't connect to wifi even if I connected anything
