Dear all, I use lwIP with GPRS modem, recenetely I found that modem using some SIM cards don't want to transmit big packets properly. And found that decreasing of TCP_MSS effects on it. Previously it was 1100 bytes. Now I set it in default value. By default this value is 536. I was thinking that this parameter negotiated when connection is setuped. What value should I set for GPRS? And why on some SIM cards modem can transmit up to 1400 bytes or so in single packet?
