RoomCast Go - Wi-Fi and QR code

Wi-Fi, Personal Hotspot and the QR code

RoomCast Go sends sound over the local network. Your iPhone and your listeners need to be on the same network.

Same Wi-Fi for everyone

Connect your iPhone to the Wi-Fi your listeners will use, then ask them to join that same network before they scan. The listening page comes from your iPhone, so the sound stays on the local network.

Personal Hotspot

No venue Wi-Fi? Turn on your iPhone's Personal Hotspot and have listeners join it. A phone's hotspot is meant for a handful of devices, so it suits a rehearsal or a small group rather than a full room.

The QR code and the link

When you go live, RoomCast Go shows a QR code and a link. Listeners scan the code with their camera, or type the link into their browser. Show the code on your screen or put it where people can see it. Your broadcast title appears on the listening page, so people know they found the right one.

If the Wi-Fi drops or the address changes

A router can hand your iPhone a new address, for example after the Wi-Fi drops or you switch networks. RoomCast Go alerts you when that happens and shows a new QR code. Share the new code: the old one points to the old address. To avoid surprises, stay on one network for the whole event.

Guest networks and client isolation

Some routers, especially guest or hotel networks, stop devices on the network from seeing each other. This is often called client isolation or AP isolation. On those networks your listeners can't reach your iPhone. Try a different network, ask the venue to turn isolation off for your event, or use your own router.

Getting good results

• How many people can listen depends on the Wi-Fi, so test with a realistic number of phones before the day.
• Keep the iPhone reasonably close to the router, and away from crowded corners of the building.
• The delay is usually around half a second, even on busy Wi-Fi. That's fine for speech and music, but not for lip-sync to a video screen.
