It would be nice if someone could make a program that shows the battery life of connected Bluetooth devices like how https://github.com/M...oothLEBatteryMonitor does so (but made in Delphi/C++ and able to show the battery life of Bluetooth devices along with Bluetooth Low Energy devices).

Windows already does this, for all supported devices. (older BT devices don't support this feature)

Go to Settings/Devices and you should see a list that looks something like this:

Screenshot - 8_6_2023 , 4_42_47 PM.png[REQUEST] Program that shows the battery life of connected Bluetooth devices

If you don't see your device in the list, it hasn't been paired with your PC.
If you see it in the list but no battery indicator, then your device doesn't support it, and no 3rd party program will make it support it. (it most likely is using an older version of BT)

I want a program that sits in the system tray and provides a pop-up/regular window which shows the device(s) that are connected and their power level.

This may be useful for you, to write your own. (or maybe not)

To expand on it a little:

Code: PowerShell [Select]
  1. # BLEPower.ps1
  2. # Credit to:
  3. # https://stackoverflow.com/questions/71736070/how-to-get-bluetooth-device-battery-percentage-using-powershell-on-windows
  4.  
  5. Get-PnpDevice -FriendlyName "*" | Where-Object { $_.InstanceId -match 'BTH' } | ForEach-Object {
  6.   $local:test = $_ | Get-PnpDeviceProperty -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' | Where-Object Type -ne Empty;
  7.     if ($test) {
  8.       "$($_.FriendlyName): $(Get-PnpDeviceProperty -InstanceId $($test.InstanceId) -KeyName '{104EA319-6EE2-4701-BD47-8DDBF425BBE5} 2' | ForEach-Object Data)%"
  9.     }
  10. }

NOTE: Apostrophes (') have been turned into ' above.

Code: Text [Select]
  1. PS T:\> .\BLEPower.ps1
  2. Basilisk X HyperSpeed: 15%
  3. Air-Fi Touch Hands-Free AG: 100%
  4. MI Portable Bluetooth Speaker Hands-Free AG: 90%
  5. QCY-Q26 Hands-Free AG: 100%
  6. PS T:\>

Note:
 - some peripherals don't report battery usage correctly, eg. the MI Portable Bluetooth Speaker Hands-Free AG above always reports 90%,
 - you need to check the device is connected since Windows retains the battery levels even when devices are disconnected, (see here: StackOverflow).

Are you asking for a program, as stated in your first post (written in Delphi or C++), or do you ask for programs source code, since a program you have found already.

Given the following on the site you refer to:
Many devices that uses vendor-specific protocols are also supported.

Unless you expect someone to spend their time snooping Bluetooth protocols between various vendor devices, anything other than what can be reported by the Windows API, (and any BT devices a prospective coder might have), isn't likely to happen.

I just want a generic one.
