My openSPOT 3 was set up to use my iPhone's Personal Hotspot so I could use it anywhere I had cell service. I have since gotten an iPhone 15 and have to set that wifi network up in the openSPOT 3. I did a factory reset on the openSPOT 3 and have it connected to my home wifi network. I can't get the openSPOT 3 to connect to my iPhone Personal Hotspot. I have now spent about a day trying to accomplish this. Can anyone help me resolve this?
