Multiple HTTP Requests - every other one fails

As a side note, these kind of traces are generated “internally” by WIP:

[WIP] closing HTTP_DATA 0x180c43e4
[HTTP] destroy request @ 180c43e4
[WIPEV] WIP_CEV_PEER_CLOSE @ TCPCLIENT 0x180c4684
[req_event] WIP_CEV_PEER_CLOSE

To enable them, you need to set the Log Events Flag:

wip_logEvents = TRUE; /* Enable all WIP Event traces */

You specify whether you want them to appear in the Trace, or on UART1 or on UART2 by using the appropriate option in wip_netInitOpts:

r = wip_netInitOpts
( 
      //WIP_NET_OPT_DEBUG_PORT, WIP_NET_DEBUG_PORT_UART1, /* WIP traces on UART1 */
      //WIP_NET_OPT_DEBUG_PORT, WIP_NET_DEBUG_PORT_UART2,
        WIP_NET_OPT_DEBUG_PORT, WIP_NET_DEBUG_PORT_TRACE, /* WIP traces in TRACE  */

      WIP_NET_OPT_END /* Marks the end of the options */
);
