Hi,

I've got a board version 1.1 ..

After some debugging I found out that the returned event values in "void WiFiEvent(WiFiEvent_t event)" do not correspond to to any predefined variable (eg. SYSTEM_EVENT_ETH_START).

My code gets a valid DHCP-lease.

The returned values for "event" are :

18
20
22

Any hint where I can find information on this .. ?

I attache the used code and the debugging output.

Thanks.

Hello Team,
We have executed example from https://github.com/Xinyuan-LilyGO/LilyGO-T-ETH-Series/tree/master/examples/TCPServer
We have 2 cases:
Case-1:
ESP32==> Router==> PC
All works well. All switch cases executed in code.

case-2:
ESP32==> PC
we are not able establish direct connection between ESP32 & PC.
Code is not executing from case ARDUINO_EVENT_ETH_GOT_IP:.
Its only printing, ETH Connected.

Your support needed to resolve this issue.

Good day! Can we use Ethernet interface for MQTT publish / subscribe. May be you have any example? Thank you!

I'm struggling getting UDP broadcast receiving with this decide.
Could you please add an UDP receiving example for broadcast packets?

Hello, i have a question. I am working with the T-ETH-POE Board and an SPI-LoRa-Shield and an 0,96 Monochrom SPI OLED.

For the OLED i used this lib: https://github.com/olikraus/u8g2
And for LORA i used this lib: https://github.com/sandeepmistry/arduino-LoRa

That is the constructor for the OLED:
U8G2_SSD1306_128X64_NONAME_F_4W_HW_SPI u8g2(U8G2_R0, /* cs=/ DISPLAY_CS, / dc=/ DISPLAY_SCLK, / reset=*/ DISPLAY_RST);

And here iam initializing the SPI for LORA:
SPI.begin(LORA_SCLK, LORA_MISO, LORA_MOSI, LORA_CS);

When i am initializing the OLED and LORA as above in writing the code together, i get the error: SPI-Connection to LORA Modul failed. Without U8G2 it works fine. Everytime when i communicate with one SPI-Interface, i put the CS-Signal LOW.

How can i work with multiple spi interfaces with the LilyGO-T-ETH board?

Many thanks!

I want to be able to select DHCP or STATIC modes.
I have the LilyGo PoE working with DHCP Dynamic mode, no problem.

However, I am unable to configure the ETH.h library with a STATIC IP address and port number?
Here is my code..

if (mode.indexOf("Static") > -1)    // WORKS when STATIC mode is selected,
{    / / STATIC MODE SELECTED
  ETH.begin(ETH_ADDR, ETH_POWER_PIN, ETH_MDC_PIN, ETH_MDIO_PIN, ETH_TYPE, ETH_CLK_MODE); // needed for LilyGo Board
  local_IP.fromString(ip); // STATIC IP Address 
  if (!ETH.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)) {
  Serial.println("Static IP Failed to configure");
  } else {
    Serial.println("Static IP configured OK.."); 
    Serial.println(local_IP); // Executes and makes it HERE, but I am unable to connect to
  }            
}
else
{  // DHCP DYNAMIC MODE SELECTED and WORKS ALL the WAY..
    ETH.begin(ETH_ADDR, ETH_POWER_PIN, ETH_MDC_PIN, ETH_MDIO_PIN, ETH_TYPE, ETH_CLK_MODE); //Added
    ip_dyna=ETH.localIP().toString();
    Serial.println("Dynamic IP: "+ip_dyna);
}   

port_dyna=port;
ETHserver.begin(port_dyna.toInt()); // Port number to be used

}

With which PoE standards exactly is this board compatible?

It's very necessary to know about what GPIOs are connected with what (pullup, led, IC, ...) when using the board.
Most of the boards maker supply it, is it possible to have it too ?

I want to use the POE part of the board and ethernet functionality. I do not need the TF CARD functionality. I'm looking for available TX and RX pins. So I can add a sensor which uses these to the board. Can you help me out? I cannot understand from the image on your website which pin has hardware RX/TX

I have powered with a 24V PoE adapter which I have from a router, but it didn't work.
Checking the temperature of the SI3404 controller, its temperature is around 70 Celsius degrees.

The voltage reaches C32, but VDD is always 0 V (VSS referenced).
I have checked D4 and C35, but they seem fine.

Did anyone have this problem too?

Do you have the dimensions for the board (a dimensions drawing possibly)?

I am looking to design and 3d print a case for the board.

Thanks

Hello good Lilygo folks!
I am very happy with your board, however i found a minor issue in your schematic (that actually has a big impact) - the R0 from your schematic are not actually mounted on the physical board. Can i suggest you ad a Nc tag to R0?

Hello!

I plan to build a device based on this module, but to design the housing I need the exact dimensions of the device, preferably a 3D model (STEP).

Could you please provide such a model?

Regards, Szymon.

Hello, PoE power burned out. Please tell me, can you give a schematic diagram of the device in order to determine the burnt elements? The microcircuit marked with a red arrow is very hot. It burned down on three devices of the same revision and the same production date. At the same time, the device is powered by USB Type-C + data over Ethernet. Can your technical engineer tell me what elements need to be replaced? Thank you.

Hello,

I have used on of your boards and installed WLED 0.14.0-b1-ESP32_Ethernet.bin

I can access the web interface of WLED when the ethernet cable is not plugged in to the port via WiFi. As soon as I plug in the ethernet cable, I lose access to the board (either wired or wireless). I have chosen what I was told was the proper ethernet board configuration for your product.

Any hints on what could be going wrong?

Greetings. tell me for what reason the ETH.linkUp() function does not work - it always returns "0"

Is there a 5V pin or a soldering point where I can access 5V?
A published schematic would be great.

I have not found this board on the website yet. This board looks like a perfect fit for a project of mine. Is there a timeline when it and the Poe add-on board will be available (preferably on AliExpress)?

I have board revision 1.1.
Using regular usb-type-c as power and LAN cable as connection to my local network

When Im running example I see
ARDUINO_EVENT_ETH_START
ARDUINO_EVENT_ETH_CONNECTED
but SYSTEM_EVENT_ETH_CONNECTED never called!
What could be the issue?

In the code example MOSI is pin 15, but on the image it shows pin 12.
The SCLK pin is 14 in the example, but 15 on the image.
What is true?
Also the use of pin 17 should be mentioned on the image for completeness.

Thanks! Steffen

Greetings,

One of the boards I purchased from you stopped working after about two weeks.

The board is extremely hot to the touch and the ESD label is partially melted.

This was after running the board for about 3 days via POE. It ran fine for about 7 days when powered by USB.

Please advise to the next steps I should take. I have 9 other boards here that I just received today, let me know if this is an issue and I should return all 10, or if it is a one off, and you will be sending a replacment.

Thank you in advance

Mike

Example code here adapted from the WiFiUDP example:

https://github.com/troyhacks/LilyGO-T-ETH-Series/blob/master/examples/UDPClientReceiver/UDPClientReceiver.ino

Works great with WiFiUDP, crashes without error or a meaningful backtrace with AsyncUDP.

I've tried to do some debugging but I'm posting here in case there's any insights.

I would love to get this board running with AsyncUDP as I'm working towards adding support for it to WLED and this is a blocking issue from finishing the integration.

Thanks in advance for any hints!

Normally, to place an ESP32 into "Flash Mode" to allow for the upload of a program, you have to press the buttons.

With there being 2 sets of buttons (one set on the Downloader module, and another set on the board itself), it is unclear on how to place the board into a mode that I can upload a program.

I am attempting to upload using the esptool software.

Thanks for the assistance.

Hi, I would like to create a 3D printable enclosure for this board. I have just ordered it and it should be arriving in about 15 days but I would like to design the enclosure in the meanwhile. Please could you upload dimensions of the board and the height of the components off the board?

Thanks.

#define ETH_CLK_MODE ETH_CLOCK_GPIO17_OUT does not work with my version of the board. I have to set the clock mode to: #define ETH_CLK_MODE ETH_CLOCK_GPIO0_OUT

If I make the above change, this code works on my board. Do the different version of the board work differently or is this a mistake in the provided ino?

Hello,

The "SI304" IC on the schematic has a signal named (V+) that does not connect to the rest of the circuit?

So, based on my reading of the schematic, the "SI3404" IC provides the power from the PoE connection, yet
I don't see where the +5vdc power comes from when only PoE is the power source for the board?

Is this signal Mislabeled?
Please see the attached schematic and screenshot.

Hiya

Apologies if I'm doing something silly, but I havent been able to upload exmaple code to the T-ETH-Lite-ESP32S3 boaerd.

Something's working because It's able to get the board info.

Any suggestions on what I can do next please? Details below.

Thanks!

I have board revision 1.1. I powered my board with a new "gigabit" 60W PoE++ injector, the device is 802.3af/at compliant and is rated with an output voltage range of 48v-56v.

As soon as I used this injector, the Ethernet no longer works. So at this point I resorted to USB power and a non PoE connection to a network switch. With the basic TCP server example uploaded to the ESP32, there is no packet transfer, but the connectivity events are triggered. When the ethernet cable is connected, the LEDs on the RJ45 socket light up, orange is flashing, green solid, the program gets as far as "ETH Connected" (WifiEvent value of SYSTEM_EVENT_ETH_CONNECTED). If I am not using DHCP, I will also see the event SYSTEM_EVENT_ETH_GOT_IP.
If I unplug the ethernet cable, the lights on the RJ45 port remain lit solid. Could the LAN8720 chip be damaged?

I have tried inserting a delay before the ethernet library is initialized. I am going to try and replace the 8720 IC on the board, but if anyone can shed any light based on the symptoms of what has happened and why, (ie could something else be damaged?) that would be greatly appreciated.

Using the proper programmer daughter board, and data LEDs flashing on that board so connection seems to be fine, but no combination of RST/IO0 is letting me flash the board.
I've tried ESPHome Flasher and PyFlasher - is there a recommended tool for flashing these boards?

Hey Lewi,

is for your udp example also a tcp example available?

https://github.com/Xinyuan-LilyGO/LilyGO-T-ETH-POE/blob/master/examples/UDPClientReceiver/UDPClientReceiver.ino

I like to traffic some tcp data into the serial monitor.

Thanks

Hi! If I use DHCP IP address, will it automatically renew when lease time expires? If no, is there a solution for that? maybe to call a function to do that? Or the only is to use a Static IP ?

I like the dimensions of the module, but I'd like to place it into an enclosure where it would be preferable to have an external antenna.

Hello,

Board used: ESP32-S3 T-ETH-Lite and WT5500

According to issue #44 we'd have to call Config AFTER ETH.begin();

I believe this line is way too early in the code:

If I move Config after the beginSPI() it works as expected.

If I do the Config in the WiFi OnEvent ARDUINO_EVENT_ETH_START or ETH_CONNECTED then it works as well.

I can't use any code to set staticIP for LilyGO-T-ETH-POE.
It can connect to the ethernet. If use staticIP, The IPs can set. But can't ping to the IP. And webserver can't be connected.
help!

hello
is there a way to get POE information?

I'm working with the board and I tried to run the example using platformio. First I want to ask if there is a prefered board just to work in platformio with the LilyGO. The second question is about the example, I ran the example on my board and I'm having the next problem, It isn't printing by serial nothing at all. This is a little bit extrange and I changed some things trying to obtain something and I couldn't. Just to finish I want to know if you have some examples on how to write in the SD card. I understand that in the example you are initializing it and printing the amount of free memory by serial.

I'm having those problems so I wait for some help if it's posible.

Thank you

Hi There,

Hello.
is it possible to transfer settings via the platformio.ini configuration file?

Hello I'm looking to use a mmWave sensor and based on the spec sheet, it requires 5V. It would be extremely handy to have a pin available to supply 5V to sensors instead of attempting to "splice" one in.
Thank you!

Can any one help creating webserver using these board and LAN8720 same , need to define static IP address and those IP access webpage for example Hello word display in webpage
I try much library from but showing error
please help ?

IEEE 802.3af, IEEE 802.3at or IEEE 802.3bt ?

use that code

// Use static ip address config
IPAddress local_ip(192, 168, 1, 44);
IPAddress gateway(192, 168, 1, 1);
IPAddress subnet(255, 255, 255, 0);
IPAddress dns(8, 8, 8, 8);
IPAddress dns2(8, 8, 4, 4);


ETH.config(local_ip,
          gateway,
          subnet,
          dns,
          dns2);

AND when try to conect a server using this code:

void sendPOST(String data) {
HTTPClient http;

http.begin("http://MY_SERVER/test.php");

http.addHeader("Content-Type", "application/x-www-form-urlencoded");
http.addHeader("Content-Length", String(data.length()));

int httpResponseCode = http.POST(data);

Serial.println(httpResponseCode);

// Comprobar el código de respuesta
if (httpResponseCode == 200) {
String response = http.getString();
Serial.println(response);
} else if(httpResponseCode >= 400 and httpResponseCode<500)
{
Serial.println("No encontrado");
} else if(httpResponseCode >=500)
{
Serial.println("Error del servidor");
}
else {
// Imprimir el mensaje de error
Serial.print("Error al enviar la solicitud POST: ");
Serial.println(http.errorToString(httpResponseCode).c_str());
}

// Cerrar la conexión
http.end();
}

RECIBE this msg:

11:09:38.941 -> -1
11:09:38.941 -> Error al enviar la solicitud POST: connection refused

WHEN use dinamic ip, don't have any problem to connect.

Thank for all help.

When i run the exmaple sketch i get phy errors. I tried changing a few things around nohting works

Hello LilyGO! Firstly i want to congratulate you for your amazing products!
I recently purchased "T-Internet-POE" ESP32. I wanted to ask if there is a pin that controls the Blue LED.

Thank you, all the best!

The board (v1.1) was working fine for a few days on PoE. Today I moved the PoeSwitch and the board to it's final destination, plugged everythign together and - nothing! No lights come up or ethernet connection established. Same result with alternative power via USB-C. With the daughter-board I can still power it up and program the ESP32.
So something wrong with the supply. On the input pin of U4 I do not see any voltage. And on D5 ther is a flaky voltage of a few hundred mV. Unfortunately there is no parts print on the board and I am not that good at trouble shooting. Any help appreciated!

hello, i have a new small problem. Sometimes after using the IO34 as an INPUT, the esp starts a reset process.

As an reset reason, i get from rtc_get_reset_reason the reason SDIO_RESET (Reset by SLC module, reset digital core).

Immediately after compiling everything works. It only triggers a reset after ca. 10 minutes if I want to close a switch between INPUT and 3.3V.

My circuit shows like this:

(I used an external Pulldown-Resistor)

What can it be?

Hello, is there a pindocumentation for the original LilyGO Downloaderboard available?

Thanks much
Martin

Hey Lewis,

one question. When i try to execute the SharingSPIBus example, the sd-interface will never mounted.

I still have my Lora Shield attached to the SPI-Bus (PIN 2, 14, 15) with a separate CS-PIN. Since this is not addressed by the example, I cannot imagine that the error came from this?

What can i do?

Hey, are there some GPIOs on LilyGO-T-ETH-POE which have the Hardware Interrupt Functionality? Maybe IO36, 39, 34, etc.

Thanks
-Martin

Hi,
I'd like to make a "hat" PCB for this board, It would be nice to have a drawing with dimensions, to not have to measure it manually. Even nicer would be a KiCad footprint :-)
