Don't know if it's relevant after so much time passed :) What I did was to add a new array that holds only the device names and pass it to the listView. private fun pairedDeviceList() { m_pairedDevices = m_bluetoothAdapter!!.bondedDevices val list : ArrayList = ArrayList() val listOfNames : ArrayList = ArrayList() // Added if (!m_pairedDevices.isEmpty()) { for (device: BluetoothDevice in m_pairedDevices) { list.add(device) listOfNames.add(device.name); // Added Log.i("device", ""+device.name) } } else { toast("no paired bluetooth devices found") } val adapter = ArrayAdapter(this, android.R.layout.simple_list_item_1, listOfNames) // Changed to listOfNames select_device_list.adapter = adapter select_device_list.onItemClickListener = AdapterView.OnItemClickListener { _, _, position, _ -> val device: BluetoothDevice = list[position] val address: String = device.address val intent = Intent(this, ControlActivity::class.java) intent.putExtra(EXTRA_ADDRESS, address) startActivity(intent) } }

@@guynimni382 Great!

Hi Emeth, thanks for the comment. Unfortunately Bluetooth and Bluetooth low energy are two completely different technologies. However we may look into doing a tutorial on Bluetooth low energy at a later date.

Would be nice. Thanks.

add build.gradle this code plugins { id 'com.android.application' id 'kotlin-android' id 'kotlin-android-extensions' }

türkmüşsün zaten bu kodları ekle

@@omeryumusak6900 thank you :)

Add this line above the line that uses select_device_refresh: val select_device_refresh = findViewById(R.id.select_device_refresh) as Button

3.0.1

Ditto. It is difficult to follow this tutorial when everything he types is deprecated.

Hi zyyystan, thanks for the comment. Here is a link to the wallpaper: bit.ly/2GB4dbu

hi, did u solved it?

@@ryszardal2631 i want to know it too

same. Have you found anything?

@@pascalschaer I am learning Flutter and Dart. That way I can write it once and use it on Android and iOS. Unfortunately, using bluetooth on something like React Native and Expo frameworks is a complete pain in the ass even though I am familiar with React.

Could it be your internet connection? I was having troubles in some areas, too, but after restarting my modem and going full screen on the video, the text was crystal clear.

Hi Ozkee, thanks for the comment. We will keep this in mind for future turorials.
