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 ...

The first connection with a new SIM card, a new module, or at a new location/tower may take aLONGtime - up to 15 minutes or even more, especially if the signal quality isn't excellent. If it is your first connection, you may need to adjust your wait times and possibly go to lunch...
Before making any connection, you have to open the GPRS connection. It can be done easily. When the GPRS connectivity is UP, the LED is blinking fast on the SIM800L module. sim800l->connectGPRS(); HTTP communication GET In order to make an HTTP GET connection to a server or thePostma...
