0.28.0

[ssilverman]

Added

• Added raw frame loopback support and a QNETHERNET_ENABLE_RAW_FRAME_LOOPBACK macro to enable.
• Added a fourth step to the MbedTLSDemo example instructions: modify the config.
• New EthernetFrameClass functions: destinationMAC(), sourceMAC(), etherTypeOrLength(), and payload().
• Consolidated all the hardware abstraction layer (HAL) functions into one place: qnethernet_hal.cpp.
• New NullPrint and PrintDecorator utility classes in the qindesign::network::util namespace.
• Added driver_is_link_state_detectable() function to the driver. This is for detecting whether the hardware is able to read the link state.
• Added EthernetClass::isLinkStateDetectable() to detect whether the driver is capable of detecting link state.
• Added setOutgoingDiffServ(ds) and outgoingDiffServ() functions for modifying and accessing the differentiated services (DiffServ) field, respectively, in the outgoing IP header, to EthernetClient and EthernetUDP.
• Added EthernetUDP::receivedDiffServ() for retrieving the DiffServ value of the last received packet.
• Added EthernetFrameClass::clear() for clearing the outgoing and incoming buffers.

Changed

• Updated the Mbed TLS version in the README and comments to 2.28.8 (was 2.28.6).
• Updated mbedtls_hardware_poll() in MbedTLSDemo example for other platforms.
• Renamed QNETHERNET_ENABLE_CUSTOM_WRITE to QNETHERNET_CUSTOM_WRITE.
• Improved the PixelPusherServer example.
• The address-changed callback is now called for independent IP address, netmask, and gateway changes.
• Improved link function documentation for linkStatus(), linkState(), and isLinkStateDetectable().
• Updated EthernetClient::setNoDelay(flag) to return whether successful.
• Add another 2 to MEMP_NUM_SYS_TIMEOUT option for mDNS, for a total of an additional 8. Timeout exhaustion was still observed with 6. Why 8 and not 7:
  • https://lists.nongnu.org/archive/html/lwip-users/2024-05/msg00000.html
  • https://savannah.nongnu.org/patch/?9523#comment18
• Updated EthernetClient::connect() to return a Boolean value. (The function signatures don't change; they still return an int.) This matches the new definition at Ethernet - client.connect().
• Changed EthernetClient::connectNoWait() return types to bool.

Fixed

• Improved marking of unused parameters.
• Fixed up use of __has_include(), per: __has_include (The C Preprocessor)
• In mDNS, ensure there's at least an empty TXT record, otherwise the SRV record doesn't appear.
• Make the alternative yield() implementation extern "C".
• Fixed EthernetUDP data copy for zero-length outgoing packets. pbuf_take() considers NULL data an error, so only copy the data if the packet's size is not zero.

Hi @ssilverman , amazing work with this library. Thank you so much.
Currently, I'm using it for two projects , one of them is a basic server which after updating the QNEthernet library an instruction in my program has come up with one error:
Instruction
EthernetServer server(14555);
Error:
error: call of overloaded 'EthernetServer(int)' is ambiguous.
I'm wondering why this is happening, and what I need to modify to make it working with the lates library version.

This is the complete program

#include <QNEthernet.h>


using namespace qindesign::network;

const unsigned int MAX_MESSAGE_LENGTH = 255;
int size;


IPAddress ip{192, 168, 0, 42};         // device IP
IPAddress sn{255, 255, 0, 0};     // Subnet Mask
IPAddress gw{192, 168, 0, 1};          // Default Gateway

EthernetServer server(14555);    // server on the 14555 port
//===============================================================================
//  Initialization
//===============================================================================


void setup() {
  Serial1.begin(57600);             // gimbal port
  Serial.begin(57600);              // USB Port

  Serial.println(Ethernet.begin(ip, sn, gw) ? "success" : "failure");   // Print if I have connection with the network

  Serial.println(Ethernet.interfaceStatus() ? "UP" : "DOWN");           // preguntar por este codigo que hace ?

  // Show whether a cable is plugged in or not.
  Ethernet.onLinkState([](bool state)
                       { Serial.printf("[Ethernet] Link %s\n", state ? "ON" : "OFF"); });

 // start listening for clients
  server.begin();
  Serial.print("server is at ");
  Serial.println(Ethernet.localIP());

}

//===============================================================================
//  Main
//===============================================================================

void loop() {


  // listen for incoming clients
  EthernetClient client = server.available();
  if (client) {
    Serial.println("new client");

     while (client.connected()) {
        serial1Event();

         delay(100);
      static byte message[255]; 
       int size = client.available(); // get the data size
      for (int i = 0; i < size; i++)
      {
        
        message[i] = client.read();
        Serial1.write(message[i]);
      //  Serial.println(message[i], HEX);
      }
      
         
    }

        // give the web browser time to receive the data
    delay(1);
    // close the connection:
    client.stop();
    Serial.println("client disconnected");
  }


}

void serial1Event() {
  
  static byte messageS[MAX_MESSAGE_LENGTH]; //Create a place to hold the incoming message
  while (Serial1.available() > 0)
  {
    
    size = Serial1.readBytesUntil('\n',messageS,255); // Read  message until the character \n
        server.write(messageS, size); // send  message to the client
        
   
  }
  return;
}

Solve like this:

EthernetServer server(uint16_t{14555});

Solved!! Thank you so much for you prompt reply. Apologies, for the mess in the code formatting.

[ssilverman]

[Would you mind modifying your post with code formatting? (i.e. the three backticks followed by “c++”) That would be helpful. Otherwise, I’ll look in a little bit.]

Example:
Begin code block with: ```c++
…Put your code here…
and then end the code with: ```

[Also, would you mind creating an issue for this, copying your comment text? (With code formatted correctly.) I’d like to make sure you’re properly attributed as reporting this.]

I fixed it up and copied the text over to the issue.
