Phone remote with no internet

Step by step: phone remote with no internet

1. Share one network. No usable Wi-Fi at the venue? Turn on your phone’s hotspot and join the laptop to it. No internet is needed after that.
2. Phone remote → No internet. In the pairing sheet, choose No internet. The laptop shows an invite code; the phone scans it and shows an answer code back.
3. Present. The two link directly over the hotspot. Next, back, notes, timer and the laser pointer all work, with nothing in between.
