client.read() returns nothing #284

Closed tkralj closed 5 years ago

tkralj commented 5 years ago

Hello. I am able to connect to the server and i get client.available() but client.read() reads nothing. Can someone help ?

Here is sample code (connect returns true, available()also but read not):

TinyGsmClient *client = new TinyGsmClient(modem);

if (client->connect(downloadServerName.c_str(),80)){ Serial.println("connected"); client->setTimeout(cfg.tout); client->println("GET "+downloadPath+"cert.der HTTP/1.1"); client->println("Host: "+downloadServerName); client->println("Connection: close"); client->println();

  delay(2000);

  String fileData ="";
  while (client->available()){
     char c = client->read();    
     Serial.print(c);
     //pazi da nismo dobili kakvo smeće po HTTPu
     if(!isAscii(c))
        continue;

     fileData+=c;
  }

// Shutdown client->stop(); modem.gprsDisconnect();

Serial.println(F("Server disconnected"));

What does your setup look like? What modem are you using? Please post the debugging output and AT log.

tkralj commented 5 years ago

Hello, here is my setup: GSMC.begin(115200, SERIAL_8N1, 36, 4); //Baud rate, parity mode, RX, TX SIM800 StreamDebugger debugger(GSMC, Serial); TinyGsm modem(debugger);

if(!modem.restart()){
  Serial.println("Failed to restart GSM modem!");
  return;
}

String modemInfo = modem.getModemInfo();
Serial.print("Modem: ");
Serial.println(modemInfo);

if(cfg.pin!=0 && cfg.pin!="")
  modem.simUnlock(cfg.pin);

if (modem.waitForNetwork()){
  Serial.println("Network found");
  networkFound=true;
  return;
}
  Serial.print("Connecting to: ");  
  Serial.println(cfg.apn);

  if (!modem.gprsConnect(cfg.apn)) {
    eth_connected=false;
  }else{
    eth_connected=true;
    Serial.print("GSM modem connected to APN: ");
    Serial.println(cfg.apn);      
    return;
  }

// Make a HTTP GET request: TinyGsmClient *client = new TinyGsmClient(modem);

if (client->connect(downloadServerName.c_str(),80)){ Serial.println("connected"); client->setTimeout(cfg.tout); client->println("GET "+downloadPath+"cert.der HTTP/1.1"); client->println("Host: "+downloadServerName); client->println("Connection: close");

  // Wait for data to arrive   
  while (client->connected() && !client->available()) {    
    delay(100);    
    Serial.print('.');    
  };    
  client->println();
  // Skip all headers   
  client->find("\r\n\r\n");
  // Read data
  unsigned long timeout = millis();
  unsigned long bytesReceived = 0;
  while (client->connected() && millis() - timeout < 10000L) {
    while (client->available()) {
      char c = client->read();
      Serial.print(c);
      bytesReceived += 1;
      timeout = millis();
  }

}

client->stop(); delete client;

Serial.println(F("Server disconnected"));

And this is with debugging option enabled. What's really interesting here is line [68766] ### which prints out all headers and content of the file correctly (content of the file is text "hello"). This means that server returned correct response but TinyGSM didn't recognize it that way. Why are this ### unhandled debug outputs and how can I fix this ?

Can you try the newest version?

tkralj commented 5 years ago

Hello, i installed version 0.7.4, & ArduinoHttpclient 0.4.0 but unfortunately, although it looked promissing from the beginning, it didn't work. The result is different than last time (there's no ### Unhadler errors) but library gets stucked in an infinte loop. Here is AT + Debug output of your HttpClient example:

I think I've found the issue. Can you try again with 0.7.7 and let close this if it works now?

Hi Sara , i tried newest version. This version cannot recognize the modem nor connect to the network so i cannot test if it gets something from URL. Here's the output from serial monitor (mind you i didnt change code from the last time at all , only updated TinyGSM):

I'm sorry Sara, it seems that mistake was on my side. TinyGSM now gets the data from my URL in expected format. I use ESP core 1.0.2 and ArduinoHttpClient 0.4.0 . Great Job Sara thank you so much !!!!! Now i will test other samples and we'll se how it goes.For now, once again, great job !!!
