No MQTT connection in Olimex ESP32-PoE board

Boards
1

Hello everyone.
I have programmed an Olimex ESP32-PoE board with the esp32-olimex-gtw-ble-wifi FW, I have configured the WiFi and MQTT credentials with WifiManager, but the MQTT connection fails.
I also enabled port 1883 in my router for the mqtt server IP address, but I can’t even ping the IP address.
This is what I see at the start-up

Can you help me?

Hello,

Depending on your model you may choose instead esp32-olimex-gtw-ble-wifi either:
esp32-olimex-gtw-ble-poe
esp32-olimex-gtw-ble-poe-iso

Hello,
I tried both images, but with both it is not possible to configure via web portal, as OpenMQTTGateway wifi network is not available.

Hello,

After some testing, and a little study to understand how MQTT works, finally OpenMQTTGateway works fine on my Olimex ESP32-POE board.
I modified User_config.h with my network parameters and now my HW supports both the wi-fi connection, when I select “default_envs = esp32-olimex-gtw-ble-wifi” in “platform.ini”, and the ETH connection when I select “default_envs = esp32-olimex-gtw-ble-poe”

Thank you and greetings
