Enabling WiFi & Ethernet together

Postby mertkahyaoglu » Thu Feb 23, 2017 2:46 pm

Hi all,

I have designed a communication card which has bluetooth, wifi and ethernet. I have searched about ESP32 and I am confused. Can i use Wifi and Ethernet at same time? Do you have reference design for this.

Best regards

Hi mertkahyaoglu,

From the software side, this is possible at the moment if you enable both WiFi and Ethernet in the "Component Config" section of IDF config. (At the moment, due to a bug, you have enable both in configuration but you don't have to use both.)

The two interfaces will be treated as independent in the LWIP TCP/IP library (ie you can bind sockets to either interface, and outgoing packets should be routed based IP packet destination address). We don't have support for source based routing or routing packets between the interfaces (ie there's no support for the ESP32 to act as a tiny WiFi router), although I think this could be technically possible.

There also isn't an example for this configuration in IDF yet, but you can make one by combining the code from one of the WiFi-based examples with the Ethernet example. Let us know if you have any trouble making this work.

From the hardware side, we don't have an official ethernet reference design yet but one will be available.

Hi All,

I already tested the ESP32 with a LAN Board from waveshare, the DP8348, and it works very good!

Now I would like to connect the ESP32 direct to my PC via the Ethernet interface, but I am not sure if it is possible at the moment.

I am asking becasue what I see now is all related to Wifi, example the DHCP stop does not work for ethernet ..

Thanks for any advice..

Regards

Juan

Hello. I'm trying to set up esp32 as an access point. Make a bridge between Ethernet LAN8720 and wifi. I looked through the Internet and didn`t found ready solutions.
Prompt please the decision or where to search for the decision.

Thank you.

Hi Espressif System Developers,

We are working on ESP8266 and ESP32 based chip and modules since one year and currently we are using ESP32 IDF 2.1 Stable IDF for our product development purpose.

Now, We want to use Ethernet and WiFi together in our board and application because we don't know customer side impact like Ethernet can be accessed or WiFi can be accessed

So, Can I use and access both ESP32 and Ethernet together into ESP32 IDF 2.1 SDK?
Regards,
Ritesh Prajapati

Hi,

Let me know if anyone has tried before to configure and use WiFi and Ethernet both together into application using ESP32 IDF.

Hi,
I tried Enabling WiFi & Ethernet together by mixing code of wifi and ethernet given in esp idf.
but it cant work. the processor is getting reboot again and again.
