I wrote a small app for iPhone that sends int that contains 3 bytes of values 0x00-0xFF to control RGB LED.
My problem is that I use the scale of 0-255 and if I use PSOCK_READTO(&s->p,'\0'); it sometimes not working well
if one of the first values is 0.
How can I overcome this problem ?

Thanks.

Take a look at PSOCK_READBUF which reads until it fills a buffer (in your case 3 bytes). Or you could ditch the PSOCK_ stuff all together and use the "lower level" uIP APIs to read the incoming data. The PSOCK_ stuff is useful if you need to do multiple socket actions (say read and write) per invocation of your UIP_APPCALL function - otherwise the "lower level" uip_ functions generally serve you better.
