I am wondering generally how an esp32 BLE sensor (linked here)functions and if it is a practical module to use in my project. I understand the proximity accuracy is far from perfect but bluetooth/wifi connection wise would one of these sensors be able to communicate with a mobile device via either wireless connection to monitor (general) proximity? I plan on building this with Arduino’s ecosystem.
I’ve done a good amount of research on various ESP 32 modules but could not find a conclusive answer.
