I am writing an IOT based (BLE) Firemonkey app and I need to check that Bluetooth adapter is Enabled or not for both iOS and Android.
I’ve found a source here but it is only for android (like many others), but I need a cross platform solution.
Answer
I’ve found a proper solution on here.
uses System.Bluetooth;
function IsBluetoothLEAdapterEnabled: Boolean;
var
manager: TBluetoothLEManager;
adapt: TBluetoothLEAdapter;
begin
Result := False;
try
manager := TBluetoothLEManager.CreateInstance;
except
exit;
end;
try
adapt := manager.CurrentAdapter;
except
exit;
end;
try
if adapt.State = TBluetoothAdapterState.On then
begin
// BluetoothLE Adapter was found
Result := True;
exit;
end;
except
exit;
end;
end;
end execute like below
if IsBluetoothLEAdapterEnabled then
ShowMessage('BluetoothLE ON')
