Hello im using this code on my new arduino R4 wifi as an access point, i can connect with the phone to the wifi but when i go to settings in realdash it wants me to put enter ip adress in wifi/lan settings. What ip adress is it looking for, is it the phones ip adress or the arduinos?
I tried both ip adresses of the arduino wifi / and my samsung phone
