Update.
I just reconfigured my Wifi network with a password.
I finally got the core to listening mode by clearing the memory and figured out the driver situation. Used the original one when it wasn’t in DFU mode. Sent the packet with the app, the core appeared to get the config info and went to breathing cyanI couldn’t quite tell. But the Android app still wouldn’t find the core.
I tried putty on COM5 and it says “can’t open the serial port”
Edit. Success it finally connected on COM5 so I could get my ID
