Hi. I want to make a test with the bluetooth on my device (the code is not mine, is from here: Android-java-code-utilities-widgets-for-Processing-for-Android/Android Arduino Bluetooth example at master · EmmanuelPil/Android-java-code-utilities-widgets-for-Processing-for-Android · GitHub ) The proble…

As a test, please see if you can run this code: import android.bluetooth.BluetoothAdapter; import android.bluetooth.BluetoothDevice; import java.util.Set; String[] devices = {}; void findPairedBluetoothDevices() { BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter(); if (adapter ==…

It works without a problem. Each device appears with their MAC adresses

This is some code that I have used in past; see if you can adapt it to your project without too much trouble. /* For use on Android devices. Has both in/out streams. Rev.2 */ import android.bluetooth.BluetoothAdapter; import android.bluetooth.BluetoothDevice; import android.bluetooth.BluetoothS…

Its basically to press one button on the phone and a led will turn on, press another button and the led will turn off, nothing more

Im doing it with an ESP32, thats why I want bluetooth serial

I’m used to data going from the board to the Android; apparently you want to go in reverse - from Android to the board.

I managed to create a very simple program, and I have a question, and is that why when I press the square it keeps sending the string even if I release the square area on the screen? import ketai.net.bluetooth.*; import android.os.Bundle; String device_name = "PROMEESP32"; String device_mac = "78:2…
