I had an idea to build a restricted zones for a phone. For example, I can't take my phone to bed, so I wanted to create a esp32 based project that beeps when the phone is too close to some areas. I made it based on BLE, but iphone masks MAC addresses, so it was impossible to track particular devices. No I realize, I could actually do it with WIFI signal straight. How I didn't think about it. Will try again today :D
