The Neo showed up as COM4. I used PuTTY to connect. But no reaction to my typing.
- Default firmware used
- Ribbon cable used
- No jumpers changed

Alright added GPIO #5 for reset in the demo config.

About Bluetooth - it is all inside the main chip, so ANY demo for ESP32 WROOM will work. I mean any BT demo for any board. Bluetooth has nothing influenced from the design or layout of the Olimex board, no pins to change, nothing.

Hello
I was using the ESP32_Gateway_Ethernet_v4.0 example config.
And for esp-idf the ethernet basic example for the v5.4.2.
https://github.com/espressif/esp-idf/blob/master/examples/ethernet/basic/README.md
I adjusted the config of this example to get it to work.
Then i changed the example code to use a tcp client connection.
Now i am trying to figure out how to advertise on bluetooth without success so far.
The device is not visible on nrf connect

Glad it is now working. Can you point me which Olimex demo exactly did you use? Link to the GitHub repo will help me fix it. Thank you.

Oke thanks i set the CONFIG_EXAMPLE_ETH_PHY_RST_GPIO=1 because it was set like that in the olimex example config.
But changing it to CONFIG_EXAMPLE_ETH_PHY_RST_GPIO=5 fixed the problem.
Thanks

ESP32-GATEWAY doesn't use WROVER chip, so it is not good idea to use "esp32-wrover-kit 3.3v" config as basis. Use some config with WROOM chip for basis.

About the config, MDC and MDIO are ok but reset pin should be either GPIO5 (it is connected to a transistor that toggles the PHY power) or set it to -1. Try with either:

CONFIG_EXAMPLE_ETH_PHY_RST_GPIO=5

or

CONFIG_EXAMPLE_ETH_PHY_RST_GPIO=-1

Hello

I am looking for some help porting the example on the github of olimex for ESP-IDF for an ethernet connection to the esp version v5.4.2. A lot of changes have happen sinds the release of the olimex example. I am starting from a basic ethernet example from version v5.4.2 and changing the configuration to set the correct pins and the other configuration. I have changed nothing for the code i just altered the configuration.
Currently the code seems to stop at the folowing code in ethernet_init.c

Code Select Expand

ESP_GOTO_ON_FALSE(esp_eth_driver_install(&config, &eth_handle) == ESP_OK, NULL,
                        err, TAG, "Ethernet driver install failed");
Before this i can log after this i can not see a log not even an error log.
Does anybody see the problem in my configuration.
For the start of the example i selected:
Target: esp32
Board: esp32-wrover-kit 3.3v
Here is my sdkconfig:

ESP32 / Re: PoE not powering

Last post by LubOlimex - July 16, 2025, 08:11:23 AM

Feels like the PoE part failed somehow. Contact us over the e-mail - support@olimex.com - provide a link to this thread and purchase number to save some time.

ESP32 / Re: PoE not powering

Last post by brettonw - July 15, 2025, 07:38:46 PM

I built the ETH-LAN demo in the Arduino IDE, and uploaded it to the board via the USB interface. After reset, I disconnected the USB and plugged in the PoE ethernet - and the board does not power up.

I've tried multiple ethernet cords, and this is plugged into a high-end, new Unifi PoE++ switch that works with every other PoE device I have on my desk. I'm certain it's not the switch or the cord.

I tried powering the board with USB while connected via ethernet cable, and it works in that case - but disconnecting the USB kills the power. The board is not picking up PoE power. The switch reports no power draw on the port.

You need to run the video output script inside the image. After login run:

olinuxino-display

then enable the specific display. Reboot.

Be very careful about the connectors and the orientation. Track pin #1. Pin #1 from the LCD should go to pin #1 from the board LCD_CON connector.
