arduino nano + enc28j60 response problem

Projects Programming

hey guys
i'm working on a project with Arduino nano+enc28j60 module.

this is my code:

static byte mymac[] = { 0x74, 0x69, 0x69, 0x2D, 0x30, 0x31 };
byte Ethernet::buffer[700];
static uint32_t timer;
const char website[] PROGMEM = "example.com";
Stash stash;
static byte session;

int ok = ether.begin(sizeof Ethernet::buffer, mymac, 10); // default pin:10
  if (ok) Serial.println("ethernet started");
  else {
    Serial.println("failed start ethernet");
    return;
  }

const static uint8_t ip[] = {192, 168, 10, 2};
  const static uint8_t gw[] = {192, 168, 10, 1};
  const static uint8_t dns[] = {8, 8, 8, 8};
  const static uint8_t mask[] = {255, 255, 255, 0};
  if (ether.staticSetup(ip, gw, dns, mask))
    Serial.println(F("ip config ok"));
  else
    Serial.println(F("ip config err"));

byte sd = stash.create();
      stash.save();
      Stash::prepare(PSTR("GET http://$F/api?action=attendance HTTP/1.0" "\r\n"
                          "Host: $F" "\r\n"
                          "Content-Length: $D" "\r\n"
                          "Connection: close" "\r\n"
                          "User-Agent: Arduino/1.0" "\r\n"
                          "\r\n"
                          "$H"),
                     website, website, stash.size(), sd);
      session = ether.tcpSend();
      // get response
      const char* reply = ether.tcpReply(session);
      if (reply != 0) {
        Serial.println("Got a response!");
        Serial.println(reply);
      }

the web request successfully send and i can get the request from server, but response (reply variable) is empty.
i'm sure that the server response back a 'hello world text'
please help me.
tnx

Please post your full sketch. If possible, you should always post code directly in the forum thread as text using code tags (</> button on the toolbar). This will make it easy for anyone to look at it, which will increase the likelihood of you getting help. If the sketch is longer than the forum will allow then it's OK to add it as an attachment. After clicking the "Reply" button, you will see an "Attachments and other settings" link.

Please always do an Auto Format (Tools > Auto Format in the Arduino IDE or Ctrl + B in the Arduino Web Editor) on your code before posting it. This will make it easier for you to spot bugs and make it easier for us to read.

When your code requires a library that's not included with the Arduino IDE please post a link (using the chain links icon on the toolbar to make it clickable) to where you downloaded that library from or if you installed it using Library Manger (Sketch > Include Library > Manage Libraries in the Arduino IDE or Libraries > Library Manager in the Arduino Web Editor) then say so and state the full name of the library.
