Once everything is ready in your smartphone and the ESP32 is running the BLE server sketch, in the app, tap the scan button to scan for nearby devices. You should find an ESP32 with the name “MyESP32”.Click the “Connect” button....

With the ESP32, you can save data on the RTC memories. The ESP32 has 8kB SRAM on the RTC part, called RTC fast memory. The data saved here is not erased during deep sleep. However, it is erased when you press the reset button (the button labeled EN on the ESP32 board). ...
