I tried to capture the traffic via PCAPdroid, but the capture does not include DHCP traffic from the client. Anyway yo do it easily?
Thanks

Hello,
To capture dhcp you need root

You need a device rooted with Magisk, then in PCAPdroid you will be able to capture traffic with root, see https://emanuele-f.github.io/PCAPdroid/advanced_features#44-root-capture for more info

The alternative would be to capture the traffic on your router, e.g. via port mirroring
