Ethernet web server

I am using esp32 as a wifi web server on which a web page runs. Everything works using the arduino library. I would like to do the same thing using ethernet w5500 using the EthernetWebServer.h libray but i don't find the instructions like "server_web.on" or "server_web.send" used by wifi, are there ...

Re: mesh network + wifi

The first problem was my fault, I was using bad a library. I have created a mesh network with some esp32 devices. The master device connects to the main wifi and communicates with the other mesh devices. The maximum number of nodes is 10, so if I want to add other devices I have to create an additio...

mesh network + wifi

I made a mesh network with three esp32 devices using the painlessMesh.h library and everything is working fine.
When I connect only one esp32 to the wifi network, it often doesn't respond to the ping for several seconds.
What can it be?

Re: IO22 - IO23 short circuit

After testing, I think I understand that the problem occurs at power on or off.
On pin EN I put a resistor from 10K to 3V3 and a capacitor from 1uF to GND.
Are there soft power on and soft power off commands?

Re: IO22 - IO23 short circuit

I think thet the module is not damaged. If I pass the solder only pin IO22 and IO23 the short circuit disappears. Technically I can't give myself an explanation.
I am using Arduino IDE, it could be the problem?

Re: IO22 - IO23 short circuit

Thanks for the tips. I measured the short circuit with the electronics off. The pcb is ok and I have already resoldered and cleaned up. The module was hand soldered, could it be so delicate that it has been damaged?

IO22 - IO23 short circuit

I am using an ESP32 Wrover module ie. During normal operation, pins IO23 and IO22 create a short circuit (about 20 ohms). The short circuit is internal to the module. The strangest thing is that if I resolder only these two pins, the short circuit disappears. If I leave the electronics on for a few ...
