we use WIZnetInterface github last version on main.c

`#include "mbed.h"
//#include "MQTTClient.h"
#include "WIZnetInterface.h"

//NetworkInterface *net;

int main()
{

while (true)
{

}

}`

we got some error from WIZnetInterface . it seem TCPSocket api version change. how can we fix it?

According to the Mbed documentation socket.recv method should return NSAPI_ERROR_WOULD_BLOCK in case it non-blocking or timeout.

But if we check the code we can see that it returns size in case of timeout (zero in many cases).

        if ((size1 > req_size) || (wait_time_ms != (-1) && t.read_ms() > wait_time_ms)) 
        {
            return size1;
        }
    }
    return NSAPI_ERROR_WOULD_BLOCK;

It seems incorrect. Am I wrong?

There is a bug in wiznetinterface.cpp. Change code in WIZnetInterface::socket_send line 574 (Tested in nucleo l476RG)
ret = _wiznet.send(SKT(handle)->fd, (char*)((uint32_t )data+writtenLen) , (int)_size);
with
ret = _wiznet.send(SKT(handle)->fd, (char)((uint32_t *)data)+writtenLen, (int)_size);

and probably too in WIZnetInterface::socket_recv line 687 (this is not tested)
retsize = _wiznet.recv(SKT(handle)->fd, (char*)((uint32_t )data + recved_size), (int)_size);
with
retsize = _wiznet.recv(SKT(handle)->fd, (char)((uint32_t *)data) + recved_size, (int)_size);
Best regards

Hi,
I would really appreciate, if you could provide example code to get at least a mbed os5 TCPSocket running. Or even Better a example for running a mqtt client in mbed os 5. (https://github.com/ARMmbed/mbed-mqtt)

Thanks a lot.

I have two different modules with the W5500 chip and both of them behave identically. They work correctly only when the reset pin is disconnected or reset functionality is commented out (last four lines in the code below):

// Reset the chip & set the buffer
void WIZnet_Chip::reset()
{
//    reset_pin = 1;
    reset_pin = 0;
    wait_us(500); // 500us (w5500)
    reset_pin = 1;
    wait_ms(400); // 400ms (w5500)

This behavior is strange because the reset functionality looks correct.

Mbed OS 5.14.2
STM32F411CEU6 (blue pill)
Please let me know if some additional information will be helpful.

ipv6 dhcp code 구현해야합니다.

Need example projects with this library
Please make a good one~~
