3 years ago Hello Divter,
Thank you for your query but DHCP is not under the scope of this project.
Anyway I would suggest you to check your dhcp configuration, /etc/network/interfaces or similar script used for network configuration. I would also suggect to check dhcp server logs if you are unsure what happening.
Alternatively to localize dhcp issue, I would suggest to set up static ip first. If that is working, dhcp problem can be debugged further.

I use esp32 spi interface to connect to rpi.The esp32 connected wifi sucessfully,but it cannot get ip from dhcp.
