  1. Hello everyone, Is it possible to create a "host name" for the wifi server running on CC3200 Launchpad?, if yes, does anyone know how or have a sample code?. Thanks.

    TCP/IP client for Tiva C connected Launchpad

    Hello JCR, Sorry for the late reply, first thanks for the help, much appreciated. Second, it doesn't work, actually if I put the "client.stop()" this way in the code it kills the whole connection with the client. I have tried also the "client.available()" and nothing as well, will keep digging and update the post with anything new.

    TCP/IP client for Tiva C connected Launchpad

    Thanks JCR for the information, quite useful one especially with a newbie to Energia syntax like me, much appreciated. Actually I'm having another problem with this piece of firmware and you might be able to help me solve it, when I turn down the client app on the PC side and re-run it the server isn't able to establish a connection and I need to restart the board to establish a link, though the board is still pingable (still I can ping), have a look on the code and let me know your opinion: #include <Ethernet.h> #include <EthernetServer.h> EthernetServer server(8888); boolean alreadyConnected = false; // whether or not the client was connected previously char TxBuffer[15] = "something here\n"; err_t error = 0; void setup() { // initialize the ethernet device Ethernet.begin(0); // start listening for clients server.begin(); Serial.begin(9600); Ethernet.enableLinkLed(); Ethernet.enableActivityLed(); Serial.print("Chat server address:"); Serial.println(Ethernet.localIP()); } void loop() { // wait for a new client: EthernetClient client = server.available(); // when the client sends the first byte, say hello: if (client) { if (!alreadyConnected) { // clead out the input buffer: client.flush(); Serial.println("We have a new client"); //client.println("Hello, client!"); alreadyConnected = true; } if (client.available() > 0) { // read the bytes incoming from the client: char RxBuffer = client.read(); // echo the bytes back to the client: client.println(TxBuffer); } } } Thanks again for the help and have a good day.
  4. Hello Gentlemen, I'm trying to develop a TCP/IP client with the new TI Connected LaunchPad board but I have some problem with the code that I couldn't figure out and maybe someone can give me a hand, here is the code (based on the Web client example but with some modifications): #include <Ethernet.h> // Enter a MAC address for your controller below. byte mac[] = { 0x00, 0x1F, 0xB0, 0x02, 0xFE, 0x30 }; IPAddress ipLocal(169,254,41,200); IPAddress server(169,254,41,198); unsigned int localPort = 8080; // local port to listen on char SendBuffer[] = "Something to send\n"; //test data char ReceiveBuffer[64] = " "; //receive buffer // Initialize the Ethernet client library // with the IP address and port of the server // that you want to connect to (port 80 is default for HTTP): EthernetClient client; void setup() { //start the Ethernet Ethernet.begin(mac,ipLocal, server); Ethernet.enableLinkLed(); Ethernet.enableActivityLed(); //Connect to server client.connect(server, localPort); //start the serial library: Serial.begin(9600); Serial.println("\n\nTCP/IP Client setup"); // start the Ethernet connection: if (Ethernet.begin(mac) == 0) { Serial.println("Failed to configure Ethernet using DHCP"); // no point in carrying on, so do nothing forevermore: while(true); } // print your local IP address: Serial.print("My IP address: "); for (byte thisByte = 0; thisByte < 4; thisByte++) { // print the value of each byte of the IP address: Serial.print(Ethernet.localIP()[thisByte], DEC); Serial.print("."); } Serial.println(); Serial.print("connecting to server\n"); //Serial.println(server); server.printTo(Serial); // if you get a connection, report back via serial: if (client.connect(server, localPort)) { Serial.println("connected to"); server.printTo(Serial); // Make a HTTP request: //client.println("GET /search?q=arduino HTTP/1.0"); //client.println(); } else { // kf you didn't get a connection to the server: Serial.println("connection failed"); } } void loop() { // if there are incoming bytes available // from the server, read them and print them: if (client.available()) { char c = client.read(); Serial.print(c); } client.write(SendBuffer); // if the server's disconnected, stop the client: if (!client.connected()) { Serial.println(); Serial.println("disconnecting."); client.stop(); // do nothing forevermore: while(true); } } //End of code On the serial monitor it displays "TCP/IP Client setup" then stops, when I try to find the board using "arp -a" command from the windows cmd it shows nothing about the board (neither the MAC nor the IP address I have assigned to it), tried to connect to the board using a small sockets example written in C++ and for sure nothing happened (just to make sure windows networking utilities aren't screwed). Thanks in advance folks
