[lwip-users] SOLVED! Re: invalid recvmbox in UDP recv() function

[gussabina]

Hello Simon:

I solved the issue!

The problem was there was not default value for DEFAULT_UDP_RECVMBOX_SIZE in
the options, so I had to add an extra line.
Just in case someone else goes though the same problem, they need to add
last line in lwipopts.h file;

/** The mailbox size for the tcpip thread messages */
#define TCPIP_MBOX_SIZE                   16
#define DEFAULT_ACCEPTMBOX_SIZE           16
#define DEFAULT_RAW_RECVMBOX_SIZE         16
#define DEFAULT_TCP_RECVMBOX_SIZE         16
*#define DEFAULT_UDP_RECVMBOX_SIZE         16*  // added to solve the
problem....

Thanks
Gus
