Control your presentations with your smartphone, tablet or Apple Watch. For this you need to start the app. Then you need to install and open PPTControl on your Smartphone, where you can select this device. While selecting, a request is sent, which can be accepted or denied. You can block new requests after successful pairing, so that only you can control your presentations.
You can download PPTControl at https://bastian-aunkofer.com/pptcontrol.
The control requires a Bluetooth connection, so this device as well as the smartphone must support Bluetooth.
To take control via Apple Watch, the iPhone must be connected to the device with the presentation (This is required due to Apple's restrictions on the Apple Watch).
