Question about Logitech R500

The answer is yes and no - I had to connect the presenter to the iPad Pro 2018 via USB dongle because the Bluetooth pairing did not work. But then you can use this presenter on the iPad without any restrictions. For one simple reason: unlike older Logitech presenters, or those from other manufacturers, this one sends left/right arrow key commands when you press the keys. The iPad also reacts to this in Keynote or PowerPoint and changes the slide. Older presenters send down/up signals when the buttons are pressed, which are correctly interpreted by iOS devices (in Safari on the iPad you can then scroll web pages), but Keynote on the iPad does not work! Conclusion: connect via USB and then presentation apps work perfectly.

According to the specification, it is only compatible with macOS, Windows and Android.
