Greetings, My project is to send some data to http server from zedboard via GSM module(through AT commands). I have designed the hardware connection in vivado (conected rx,tx,vcc and gnd pins in JB connector) . I have set the baudrate to 115200(for modul
char server[] = "arduino.cc"; // the base URL char path[] = "/latest.txt"; // the path int port = 80; // the port, 80 for HTTP void setup() { // initialize serial communications Serial.begin(9600); Serial.println("Starting Arduino web client."); // connection state boolean ...
