I have now tested the w5200 curcuit for some time.
I have an issue when connection to a WEB server over a 3G modem to send data to a server with http POST.
If I post a message from a normal web client, like safari it works.
But when I try to connect to the WEB server on the same network it fails to connect
If I use an adsl connection it connects both the W5200 and the safari and sends the information correctly.
setIMR(0x07); // Interrupt registers for W5200 setRTR(10000); setRCR(3); openTCPSocketOnPort(1, destinationPort); vTaskDelay(2000); connect(1, destinationIP, destinationPort); vTaskDelay(2000); uint8_t temp = getSn_SR(SOCKET_1); if( temp == SOCK_ESTABLISHED)
I am using the interrupt and get’s 08, timeout but with the safari browser it works.
I am getting a little desperate here. Can you please send me some hints?
Looking forward to a reply
