Unable to Program Custom ESP32-U4WDH

I've created plenty of custom ESP32-WROOM boards before but this is my first ESP32-U4WDH.

In SoftAP DHCP Server Eventually Stops

When connecting to an ESP32 in softAP mode from an ESP32 client, the client connects and disconnects just fine for a while. Eventually, the AP will show the following error: dhcps: send_offer>>udp_sendto result ffffffff The client connects but doesn't get a lease. If I try to connect from another de...

IO34 & IO35 with Reed Switch & ESP32

So I know IO34 & IO35 are read only on the ESP32. However, when I try to attach a reed switch to the pins, I'm unable to read anything but a 0. Using them as interrupts doesn't work either. Moving the reed switch to pins IO32 & IO33 works fine. You can see the 10k resistor attached to the reed switc...

Get MAC of Station on Connection/Disconnection on SoftAP

I'm trying to get the MAC address out of the WiFiEventInfo_t when the client connects or disconnects. What is the proper variable to look at?

WiFiEventInfo_t info

info.connected.mac is not valid.

Any pointers would be helpful.
