why my bluetooth list not showing in listpicker, pls help

[mellifluousphilosophers]

The reason Bluetooth devices may not appear when I press the 'Devices List' button on my phone could be due to what? I urgently need it for my internship assignment

[Ivan-Ko]

I have some error message: no matching function for call to 'BluetoothSerial::BluetoothSerial()', BluetoothSerial SerialBT; Can you help with it please?

[linuxrobotgeek]

Got this to work after failing with the Pico W. Even with new BT support things are still a bit rough.

Why don't I see any bluetooth devices when entering the app? Although I have already connected the HC-05.

Hi, i am creating a device that has esp32 and the other device is Pi5 which runs android os an app can be installed in this os . Now, i need to connect my esp32 with the pi5 only . Can you guide how i could do this ? In my mind .. it is giving characterstic id call from esp32 and the app would have the same the characterstic app . If the app detects the characterstic uuid , then connect directly to esp32 . Please let me know if this is right or show a video on how to do this as a refernce

Hi can you do tutorial to display multiple ir sensor and update to the apps using MIT App Inventor? Example parking slot. If slot 1 available the ir sensor send data to the apps and text on the saying slot available. And if slot 2 has been parked the apps will display slot 2 has been parked.
