Hi, I’ve been having a hard time connecting the esp32 to my smartphone, when I click the connect option its either blank or it doesnt connect. I’ve managed to connect it but it gives a reading of -127, so far I have upgraded the Bluetooth extension and granted all permisions to the app.

Hello elllla,
- Can you check your sensor connections? It looks like your sensor has something missing that is failing to read it.
- What do you see in your Arduino IDE serial monitor?
- Do you have another DS18B20 sensor to test that project?
