Losing data when using the UIPEthernet Mbed library

Application development
1

Hello! Using the UIPEthernet by @hudakz I have a problem: more than about 90% of the packets I send over UDP are lost. I have ENC28J60 module, microcontroller with MBED
and UIPEthernet library, I accept UDP data from the computer on ENC28J60 and everything works well, But the situation manifests itself only when I send more than two packets from the computer at the same time (of course, the computer does not send them “simultaneously”, I mean that the packets go one by one close to each other) I checked on other devices and when the computer-to-computer connection via Ethernet, everything works perfectly, but when I connect the computer to my ENC28J60 chip, a problem arises.

As far as I understand, if the microcontroller does not have time to pick up from the ENC28J60 it should be stored in a special memory inside the ENC28J60 and this should solve my problem, but no. Can anyone know what I am doing wrong and what is the mistake? I am attaching a part of the code in which the UDP reception is processed. I am a beginner in development, thank you all for help!

/////the code below runs endlessly in a circle after initializing and opening a socket with the desired port 

int size = socketReceive.parsePacket();

    if (size > 0)

    {

      do
      {
        char *data = (char *)malloc(size + 1);
        int len = socketReceive.read(data, size + 1);
        data[len] = 0;
////////
///in this section, things are done with data and everything is ok
///////
        free(data);
      } while ((size = socketReceive.available()) > 0);
    }

  }

Hello,

  • Which revision of Mbed OS do you use?
  • What is your Mbed target board?
3

revision of Mbed OS - 6.60600.210128 (6.6.0)
target board - Nucleo f446re

I would suggest to try the new ENC28J60-EMAC driver rather than to use the old UIPEthernet library. It’s based on the native Mbed OS 6 Ethernet stacks and the hardware interface is the same as in case of the UIPEthernet. The biggest advantage of the ENC28J60-EMAC driver is that the application program code is same as in case of the native Mbed OS EMAC driver. This enables you to run all the Mbed OS 6 examples, the UDPSocket example included.

Thanks for the answer! I will try to follow your advice, I hope this helps…

Hello! Maybe you could tell me…

I’m trying to use the new ENC28J60-EMAC driver and have some problems, when adding json files to the project.
During compilation, I see this error

“mbed build API internal error
Attempt to override undefined parameter ‘enc28j60-emac.mosi’ in ‘application [*]’”

I build the project in VS Code with Platformio. Maybe I somehow inserted your library incorrectly?
I just put the source folder “ENC28J60-EMAC” to the project directory and wrote #include “ENC28J60-EMAC / enc28j60_emac.h” in main.cpp

I will be infinitely grateful if you tell me, thanks for your time!

I’m very sorry but I am not familiar with the Platformio and I have no idea how to add a library to such projects.

Do not include any ENC28J60-EMAC related header file into the “main.cpp”!

Nice work! It would be great to have the Mbed OS connectivity tests passing within this component! I am interested in it too, I would be happy to contribute if I have some free time.

If I manually set a MAC address in the get_default_instance method these are the results. Please take a look and give me a feedback if you can @hudakz

Hello David,

Thank you for running all these tests. However I’m just a hobbyist and have no idea how to use them to improve the ENC28J60-EMAC driver. So far I had success to use the driver for building a TCP (HTTP) server, TCP (MQTT) client, UDP server and a UDP client. However, the UDP client cannot receive data from an official NTP server but only from a “local” UDP server.

13

Ok, don’t worry. Thank you by your work. If I have time I can take a look to the implementation and try to make it pass the tests.

Hello Hudakz!
I managed to run your new emac driver in platformio but still have some confusion…
maybe you know why UDP messages can be sent this way?

Screenshot 2021-11-30 at 18.07.55
Screenshot 2021-11-30 at 18.07.551920×498 149 KB

the screenshot shows UDP messages on the receiving side of the connection, but for some reason, what I send via UDPsocket is sent only the first time, as UDP, and then as some unnamed packet.

I also noticed a strange behavior that if you remove printf from the code below, then no UDP is sent at all.

 char sbuffer[] = "test!!";
 int scount = socketTransceive.send((uint8_t *)sbuffer, sizeof sbuffer);
 printf("sent %d [%.*s]\n", scount, strstr(sbuffer, "\r\n") - sbuffer, sbuffer);

maybe you know what could be the problem? maybe you can give me some documentation about porting EMAC? thank you in advance for your time

Sorry, but I don’t know what’s wrong. You can find the porting guide here.
