WT32-Eth01 network interface not online

#1 Post by pinie » 11 May 2022, 08:50

Hello,

I'm using a WT32 Eth01 (1.2) and flashed the part with ESP32_4M316k-ETH-factory (mega 20220427). Actually, everything works great over WiFi. When I plug in a network cable I don't get the part online. The LED on the network socket does not even light up. Network cable everything OK Am I wrong in thinking or what am I doing wrong? Does anyone have a tip for me?
Thanks very much!

N.B. after you double-checked the settings, you may want to use one of the latest test builds from the Github Actions page (you need to be logged in in Github to download the zip files) https://github.com/letscontrolit/ESPEasy/actions

I did fix a few things related to Ethernet.
There is an issue where ethernet events are only fired once, so disconnect/reconnect is not detected -> fixed
Typical use case; Ethernet gets disconnected (e.g. connected 4G router reboots), WiFi is started to search for networks, Ethernet gets reconnected, WiFi is turned off.
However when turning off WiFi, the received DNS records via DHCP are then erased => Somewhat patched, not really happy with the fix yet, but it works.

Hello,

Unfortunately, I am not familiar with the Github. Which file should I load. I've logged in. Which file is the right one for the WT32-Eth01? Thanks very much.

- Select one of the succeeded builds in the Actions tab, like this one: https://github.com/letscontrolit/ESPEas ... 2303327656
- Then from the Artifacts download the Binaries file
- Then open that file using a zip tool like 7zip, maybe the Windows default unzipper will also handle it correctly
- In that file you will find a series of zip files per build configuration, extract the .zip file similarly named to the one you used before
- In that file you will find a bin folder that holds the 'regular' .bin file for use via the Tools/Firmware update feature, and also the .factory.bin file for uploading via an external Flash tool

Hello,

I would never have found that. Thanks very much. The interface is now running. But first I had to remove the data from the WLAN (IDs). Only then did the ESP use the Ethernet interface. Is that normal?
Now I wanted to use the GPIO. I don't see any system in the name. Which GPIO is now which pin?
Maybe I have a misconception?

Thanks very much!

Do you mean for configuring the ETH connections or GPIO numbering in general?

Also you can set the "Preferred network medium" on the "Hardware" tab in the web interface.

AFAICS, there is a setting on the Hardware tab that determines the Preferred network medium, WiFi or Ethernet.

Does this Googled image look like your device?

The IOnn pins are the names for the GPIOnn, and you should be able to control them using the regular GPIO,nn,<0/1> commands

Hello,

the preferred usage was set to Ethernet. Nevertheless, he always used WiFi. But I can test that now.
I meant the general GPIO. I need 4 pieces as "IN" and don't know which PIN that is on the board. On the surface I see many GPIO that I can define. e.g. GPIO 13 which PIN? Apparently some are "hidden". I can't make sense of the documentary either and it doesn't make any sense to me.

Thanks!

Hello,
I really have a problem with the GPIO designations. I want to connect an I2C sensor. According to the surface, this is GPIO 4 (SDA) and GPIO 5 (SCL). According to the label, there is no GPIO 5 or IO5 on the board. This totally confuses me. There is IO35 or IO15. Using the IO35 as a GPIO was unsuccessful. I can't find any information online either. Does anyone have a tip which PIN are for I2c?

Thanks very much!

GPIO 4 & 5 are the defaults for many ESP8266 boards.
But to be honest, those defaults are not useful for I2C on ESP32 boards.
(which reminds me, I still have to set the defaults for I2C pins on ESP32 builds to something else)

Anyway, see the best pins to use for ESP32 boards:
https://espeasy.readthedocs.io/en/lates ... e-on-esp32

This list does not include the (many) pins used for LAN boards, so not all pins mentioned here will be made available on your board.

For I2C you must use pins that can be used both as input and output, so the highest numbered pins will not be usable as those are input-only.

Only use pins which are marked green on both input and output on the page I linked above. (and of course which are available on your board)
Then set these pins on the Hardware tab of the ESPEasy web config page as I2C pins.

Hello,
thank you for your hint. That helps. I am now trying to create an overview. The question is which PIN of the ESP 32 circuit is routed to the circuit board. Under what name is it then written on the board. Then the cables have to be plugged in. You have to be careful which PIN you are talking about. Do you mean the PIN of the circuit or the PIN on the board? Am I completely off the mark now? Or the question: On the board e.g. PIN "IO35" what is behind it?
The link helps with my research.

Thanks!

IO35 is shorthand for GPIO 35, as there isn't enough space available for the label... ;)

Hello,

Sorry, I probably thought too complicated. The data sheet of the WT32-Eth01 contains PINS that don't make any sense. Regardless, I admit I don't see through. I just take the imprint on the board and that's it. With the info from above, I then set the ports for I2C.
Thank you for your patience.

Thanks!

Hello,
I have to revisit the subject. I got the basics of GPIO. Attached is an overview which I created from a lot of information.
My problems with the Ethernet interface persist. I have the bin file (loaded as described above). I can now partially use the Ethernet interface. But she's really slow and sometimes I lose her completely. If I unplug the network cable, it switches to WLAN and everything is quickly and reliably accessible. Does anyone know the exact GPIO which exactly the Ethernet interface needs? The interface is particularly important to me.

Thanks very much!

Can you update to a recent PR build from Github? Like from this (successful) Github Actions run: https://github.com/letscontrolit/ESPEas ... 2362970718 as this has a lot of improvements regarding Ethernet included (from Espressif IDF 4.4).
Download the Binaries .zip file, and you can extract the build you've used earlier, then upload the .bin (not .factory.bin) via the Update Firmware feature on the Tools page.

I do see a crystal on the picture you published.
Are you sure the clock setting is correct?
I would expect this to be GPIO-0 external crystal.

Hello,
that's exactly what I assume too. I flash the WT32 Eth01 and set the GPIO for the Ethernet. Then I start and expect the interface to work. I don't have that point. Just like in the photo. At times, however, the interface is very unreliable and slow. Do I have a general misconception?

Thanks very much!

I have not tested these specific boards myself, but I do have tested several ESP32 boards with Ethernet and "slow" is absolutely not the word I would use to describe its behavior.

One thing I do know is that with insufficient power, the voltage may drop on the Ethernet chip which may cause the Ethernet connection to switch between 10 Mbps and 100 Mbps. This may of course result in a rather unusable network experience.

If you have a switch that may be able to show the connection speed (e.g. one of those TP-Link SG-105E or 108E units, Netgear has a very similar range with an "E" in the model nr) you can check this.

An ESP32 itself may typically use 100 - 160 mA. But with Ethernet connected, this may easilly be 100 mA more.
This extra current can be enough to cause voltage dips, especially if the used cables (or connectors) add some extra resistance like thin cables do.
The power consumption of the Ethernet chip is rather "noisy" in that it draws significant currents at 50 MHz.
So maybe you can also add a 100 nF + 22 uF capacitor between the 3V3 and GND, with the 100 nF as close as you can to where the ethernet chips is connected to 3V3.

Hello,

That's a really interesting approach. According to the data sheet, the WT32 Eth01 should draw up to 500 mA. I installed a 5V 600mA mini power supply in my project. At first I thought I made a mistake on my circuit board. Then I exchanged the WT32 and it ran then. The supposedly broken one ran on a larger power supply without any problems. Sometimes I flash the WT32 via the USB port on the computer. The normal USB port can handle 400mA. If our theory is correct, the WT32 works in the border area. This can theoretically lead to such phenomena (unstable and slow). I just ordered bigger power supplies to test the thing. I ask myself a question anyway. It must be a general problem. Why isn't anyone hearing about these problems on the net? I didn't choose this part for nothing. I definitely wanted to set up my alarm system via Ethernet and not via WLAN. Otherwise I would have taken an ESP8266 and the thing would be done. The heart of the WT32 Eth01 is the Ethernet interface and it should actually work. I am testing this with the power supply. So I can't use the part at the moment.
Is someone's Ethernet interface running stably and without failures????? If so, what power supply?

Thanks very much!

The 500 mA is the peak, but only when using WiFi (and I think the peak might be slightly more if Ethernet is on while using WiFi)

But keep in mind that the power supply is only one part of the equation.
The cable between power supply and board is equally important, if not more important.
Having a good USB cable is really important for good stability.
And also cables considered to be "high quality" can fail on some boards as there seems to be quite a high tolerance on how far the pins of a micro USB female port (the one on the board) may stick out.
I've had some issues with some boards where this connector apparently had slightly shorter ones, so one cable failed and the other one worked fine.

Key features of a good USB cable:
- Thick wires inside
- Good contact on the micro USB (or on some newer board USB-C) plug.

Some of these issues can be overcome by adding some capacitors on the board itself.
But that's still a trade-off, as larger capacitors tend to draw too much current when charged from being completely discharged.
Also it makes a difference whether you place the capacitors on the 5V or on the 3V3 side.
But I guess that if the voltage dropped too far on the 5V side you would also see reboots of the ESP with reboot reasons like "Brownout detected"

Hello,

You are absolutely right about the cables. However, the WT32 ETH01 does not have a micro USB interface. In my case I made a small circuit board and built it into a plug-in power supply case. The contact is fully given by the conductor tracks. But I repeat my question. Is someone's Ethernet interface running stably and cleanly? Is the board still in the testing phase? I only want to evaluate 4 window contacts (GPIO-IN) with my part and have connected a BME 860 for temperature etc. via I2C. Or is a clock problem why the interface is so unstable?

Thanks very much!

What exact clock settings are you using?
It seems to have an external clock, meaning you should select that there is an external clock on GPIO-0.
The last screenshot you posted does not show that setting.
It should state "External Crystal Oscillator" on the "Ethernet Clock" setting.

Hello,

now i have to ask something. Do I need to connect a cable to GPIO 0? If so, where does it have to go? Currently I have only supplied the board with voltage. I don't notice the 4 GPIO and the I2C interface at first. Maybe that's the problem. I thought the Ethernet interface was already fully connected internally on the board?

Thanks very much!

GPIO-0 must be available externally as you need to pull it to GND at boot (power cycle boot on ESP32, as it doesn't check the pin state during normal reboot) to enter flash mode.
I don't know how it is done on this board, but on my own board designs using external crystal for Ethernet, I use a switch chip to only connect the 50 MHz clock to GPIO-0 after the LAN chip is powered on.

GPIO-0 is always a bit tricky to use as it may never be pulled down unintentionally when the ESP boots.

See also this link for what pins to use: https://espeasy.readthedocs.io/en/lates ... e-on-esp32
But keep in mind the LAN adapter does need a lot of pins. I guess most of them are not even connected to the outside as they are dedicated on this board to the LAN8720 chip.
Only 3 pins can be configured for LAN and there is often a pin used to control the power to the LAN chip.

Hello,

now the interface is stable. See settings in the photo.
I can't say if it's the new version. Regardless, I'm really happy. I still have a small problem. The BME 860 is not present in this version. I know somehow you can adjust that via Atom, but of course I want to keep the current version. Is there a link where I can download the current version with the BME 860?
Then all my problems would be gone and my little project can go live.

Thanks very much!

For support of the BME680 you need a TESTING B build that has test_B and _ETH in the name, not sure what you have installed last, but if you downloaded from a github actions build, as guided before, that same zip file should also have that test_B_ESP32_4M316k_ETH build included.
You can use the Update Firmware button on the Tools page to update with that .bin (without .factory in the name), upgrade is possible with keeping the current settings as-is, same version = no conversions needed :)

Is BME680 support still in Beta test? Any outlook on when it will be in the mainstream of ESPEasy?

The TEST builds have been renamed to Collection (with the same A..E-suffixes), as 'test' was not covering the actual contents anymore.
The BME680 is quite stable, as no support requests have been made on that plugin since it was included, AFAICS.

I've been struggling with WT32 for some time now.
It already worked for me, I have Wi-Fi, IP for Wi-Fi and LAN set up.
I moved the module where wifi is not set.
But the module does not create an AP for me so that I can change the ssid.
Why?

You seem to have partly configured a Static IP, but possibly not set the desired IP address, then it will have trouble to start anything network related.
Your logs are really early after boot, sometimes it just needs some more time to initialize the ethernet connection.
You can change the network configuration via the serial terminal you seem to have in use, check out the IP, Subnet, Gateway and DNS commands (documented on this page), and also the same with eth prefix (ethip, etc.), for the Ethernet counterparts. (these seem to be missing from the documentation :?, I'll have a look at that later).

I solved it by making a new Flash.

Is it sent as a text to Ascii?
When connecting to the ESP via an USB-serial adapter, using some terminal software, you can also type commands to the unit, similar to when typing in the Command entry of the Tools page. The 'restrictions' are that you won't see what you type until you press Enter, and you can't correct typos by using the backspace key. But you can always re-type a command ;)

I reloaded FW EspEasy another edition and factory
through
flash_download_tool_3.9.5
Settings are cleared and AP created.
It was probably enough to send Reset through the terminal.

Terminal works.
That's good help.
I'm wiser again.
Thank you very much.

The problem appeared again.
I will transfer the WT32 from the second wifi to the first.
Created by AP.
I set via WEB>
Static IP: 192.168.1.75 GW: 192.168.1.1 SN: 255.255.255.0 DNS: 192.168.1.1 / 0.0.0.0
But it didn't connect to WIFI.
But I see this in the log
502246 : Info : IP : Static IP : GW: 192.168.1.1 SN: 255.255.255.0 DNS: 192.168.1.1 / 0.0.0.0
I entered the IP to enter through the terminal:
> IP, 192.168.1.75

OK
> ip

IP: 192.168.1.75

OK
And he verified.
But I still see it in the log
696919 : Info : IP : Static IP : GW: 192.168.1.1 SN: 255.255.255.0 DNS: 192.168.1.1 / 0.0.0.0

I noticed that the IP is displayed after the restart and then I can't see it:

Otherwise, I am sure that I had the IP filled in when I first saved it on the WEB.

It seems that the problem was in the power supply.
There are small capacitors on the WT32 module.
I am not sure if there is even a 10u capacitor for 5V on the board as it is in the schematic.
Physically, it is too small for such a value.
After adding the capacitor, the module still works.
I hope nothing will change.
Thanks for help.
