[BUG] esp32-devkitc:wifi seems not working correctly

[acassis]

Description / Steps to reproduce the issue

Steps to reproduce:

$ ./configure.sh esp32-devkitc:wifi
$ make menuconfig
Application Configuration
    Network Utilities  --->
        -*- Network initialization  --->
            WAPI Configuration  --->
            (MyRouter) SSID
            (MyPasswd) Passprhase

$ make -j flash ESPTOOL_PORT=/dev/ttyUSB0

Open the serial console and note that it connected:

nsh> ifconfig
wlan0   Link encap:Ethernet HWaddr 08:3a:8d:95:af:3c at RUNNING mtu 1500     
        inet addr:192.168.1.10 DRaddr:192.168.1.1 Mask:255.255.255.0         

However it cannot ping external host:

nsh> ping 8.8.8.8

Also if you try renew command it will fail:

nsh> renew wlan0                                                                  
ERROR: netlib_obtain_ipv4addr() failed                                            
nsh>

Workaround:

Clear the SSID and Passphrase on menuconfig, when the nsh start you can connect manually and setup the network this way:

$ wapi psk wlan0 MyPasswd 3
$ wapi essid wlan0 MyRouter 1
$ ifconfig wlan0 192.168.1.51 dns 8.8.8.8

Now ping 8.8.8.8 or ping google.com will work.

ping @tmedicci @fdcavalcanti @eren-terzioglu for visibility

Seems to be DHCP related.
Looking at the logs, the wapi essid command connects successfully and like you said, manually setting the IP works fine.

Thanks for reporting!

@fdcavalcanti thank you for reproducing the issue, in fact this board config is missing DHCP support:

Hey that's great! I'll submit a PR after testing and double checking the other devices.
Thank you @acassis

[fdcavalcanti]

@acassis I tried here and your suggestion did not work. I still get the same error. Are you on master branch?

@fdcavalcanti no, now I am testing 12.12-RC0. In fact I remember I tested enabling the DHCP yesterday and it didn't fix. Today I was thinking I had done something wrong yesterday, but now that you tested mainline, probably that is some recent regression.

@fdcavalcanti may you try some previous version (ideally do git bisect) to find the issue?

[fdcavalcanti]

This seems ESP32 related. It is working fine on ESP32-S3 and they share the same wireless driver.
However, I noticed ESP32-C3 is also failing on DHCP, so perhaps there is more than one issue one our network drivers.

[acassis]

@fdcavalcanti so in ESP32-S3 the issue doesn't happen?
