To pair a Yealink share button (wireless presentation pod) with a RoomCast or RoomCast E2, plug the button into a USB port on the RoomCast unit while it's powered on and wait for the on-screen message that pairing is complete, then unplug it. The button is now linked to that RoomCast and will share to it with one press. Yealink sells RoomCast with WPP20 or WPP30 pods depending on the region; Yealink notes that WPP30 isn't available in the US market, so US rooms normally use WPP20.

What the button does
A wireless presentation pod is a USB device that plugs into a laptop. Press it and the laptop's screen appears on the room display through RoomCast, with no app or network setup. Up to four people can share at once on the screen. Buttons are the simplest option for guests; people can also cast with built-in protocols. See button and dongle wireless presentation systems explained.
Button models
| Pod | Notes |
|---|---|
| WPP20 | Yealink wireless presentation pod, USB. The usual choice for US RoomCast bundles. |
| WPP30 | Newer pod sold with RoomCast in some regions. Yealink states it isn't available in the US market. |
| PA20 | A Yealink presentation accessory sometimes listed with RoomCast in other markets. Confirm compatibility with your RoomCast model and firmware on Yealink's support site before buying. |
Compatibility can change with firmware. Check the current RoomCast E2 release notes or datasheet for the list of supported pods. Firmware is covered in RoomCast firmware update and download.
How to pair a button
- Power on RoomCast and make sure the room display shows its home screen.
- Update first if possible. Pairing new pods works best on current firmware.
- Plug the pod into a USB port on the RoomCast unit.
- Wait for the pairing prompt on the display. When it says pairing succeeded, unplug the pod.
- Test it: plug the pod into a laptop, wait for its light to show it's ready, then press the button. The laptop screen should appear on the display.
- Repeat for each pod. Label pods with the room name so they don't wander.
A pod pairs to one RoomCast at a time. Pairing it to a different RoomCast moves it to the new room.
First-time use on a laptop
On first use, the laptop may need to run a small sharing app from the pod (it appears as a USB drive). On managed company laptops, IT may need to allow it. If nothing happens:
- Try a different USB port, or use the correct adapter for USB-C laptops.
- Check that the laptop allows USB storage and running the app.
- Re-pair the pod to the RoomCast.
Troubleshooting pairing
| Problem | Fix |
|---|---|
| No pairing message | Try another USB port on RoomCast; reboot RoomCast and retry. |
| Pod pairs but won't share | Re-pair, update RoomCast firmware, test on another laptop. |
| Laggy or dropping share | Reduce Wi-Fi interference, move RoomCast closer, or connect RoomCast to Ethernet. |
| Pod works in one room only | It's paired to that room's RoomCast. Pair it in the new room. |

Replacement and extra buttons
Lost or broken pods can be replaced individually and paired with the steps above. Buy the same pod model your RoomCast supports. If you're replacing the RoomCast itself: the original RoomCast reached end of sale in February 2025 and RoomCast E2 replaces it. See RoomCast vs RoomCast E2.
