Meta Quest (SideQuest)

Sideload the MeshChatX Android APK onto Meta Quest.

The MeshChatX Android APK runs on Meta Quest 2, Quest 3, Quest 3S, and Quest Pro. Quest headsets run a modified Android runtime, so the same universal APK published for phones and tablets can be installed by sideloading.

MeshChatX opens as a 2D panel inside your VR environment. It is not a native VR application. You get the full MeshChatX web UI in a floating window while you remain in your Quest home space.

What you need#

  • A Meta Quest 2 or newer headset
  • A Meta account with Developer Mode enabled
  • SideQuest on your PC (desktop app) or access to the SideQuest web installer
  • A USB-C cable (for wired sideloading) or a working wireless ADB setup

Get the APK#

Download the latest signed Android APK from the MeshChatX releases page. Release assets are named like ReticulumMeshChatX-v*-android-universal.apk.

You can also build the APK yourself. See android/README.md.

Enable Developer Mode#

  1. Install the Meta Horizon app on your phone and pair your headset.
  2. Open Menu -> Devices -> select your headset -> Developer Mode.
  3. Turn Developer Mode on and accept the prompt on the headset if asked.

Developer Mode is required for sideloading and for SideQuest to see the device.

Install with SideQuest#

Wired install (typical path):

  1. Connect the Quest to your PC with USB-C.
  2. Put on the headset. Accept Allow USB debugging when Meta prompts you.
  3. Open the SideQuest desktop app. Confirm the headset shows as connected (green dot).
  4. Click Install APK file from folder on computer (or drag the APK onto SideQuest).
  5. Select the ReticulumMeshChatX-v*-android-universal.apk file you downloaded.

Wireless ADB works when your PC and headset share a network and SideQuest can pair over Wi-Fi. Follow SideQuest's wireless pairing steps if you prefer that over USB.

Launch on the headset#

  1. Open the Apps library on the Quest.
  2. Filter to Unknown Sources (or Unknown on newer Horizon builds).
  3. Select MeshChatX.

The app opens as a 2D panel. Grant microphone permission if you plan to use LXST calls.

First run#

MeshChatX stores data under the Android app sandbox like any other APK build. Add a Reticulum interface from Interfaces before you expect mesh traffic. Quest Wi-Fi only reaches your LAN and the internet. It does not replace a mesh uplink unless you configure one (for example a TCP client to a known peer).

For native Android builds (not Termux), see android/README.md.
