/* * UIPEthernet TcpClient example. * * UIPEthernet is a TCP/IP stack that can be used with a enc28j60 based * Ethernet-shield. * * UIPEthernet uses the fine uIP stack by Adam Dunkels <adam@sics.se> * * ----------------- * * This TcpClient example gets its local ip-address via dhcp and sets * up a tcp socket-connection to 192.168.0.1 port 5000 every 5 Seconds. * After sending a message it waits for a response. After receiving the * response the client disconnects and tries to reconnect after 5 seconds. * * Copyright (C) 2013 by Norbert Truchsess <norbert.truchsess@t-online.de> */ #include <UIPEthernet.h> #include "utility/logging.h" EthernetClient client; signed long next; void setup() { #if ACTLOGLEVEL>LOG_NONE LogObject.begin(9600); #endif uint8_t mac[6] = {0x00,0x01,0x02,0x03,0x04,0x05}; Ethernet.begin(mac); #if ACTLOGLEVEL>=LOG_INFO LogObject.uart_send_str(F("localIP: ")); LogObject.println(Ethernet.localIP()); LogObject.uart_send_str(F("subnetMask: ")); LogObject.println(Ethernet.subnetMask()); LogObject.uart_send_str(F("gatewayIP: ")); LogObject.println(Ethernet.gatewayIP()); LogObject.uart_send_str(F("dnsServerIP: ")); LogObject.println(Ethernet.dnsServerIP()); #endif next = 0; } void loop() { if (((signed long)(millis() - next)) > 0) { next = millis() + 5000; #if ACTLOGLEVEL>=LOG_INFO LogObject.uart_send_strln(F("Client connect")); #endif // replace hostname with name of machine running tcpserver.pl // if (client.connect("server.local",5000)) if (client.connect(IPAddress(192,168,0,1),5000)) { #if ACTLOGLEVEL>=LOG_INFO LogObject.uart_send_strln(F("Client connected")); #endif client.println(F("DATA from Client")); while(client.available()==0) { if (next - millis() < 0) goto close; } int size; while((size = client.available()) > 0) { uint8_t* msg = (uint8_t*)malloc(size); size = client.read(msg,size); #if ACTLOGLEVEL>=LOG_INFO LogObject.write(msg,size); #endif free(msg); } close: //disconnect client #if ACTLOGLEVEL>=LOG_INFO LogObject.uart_send_strln(F("Client disconnect")); #endif client.stop(); } else #if ACTLOGLEVEL>=LOG_INFO LogObject.uart_send_strln(F("Client connect failed")); #endif } }
