I built MeshLive: video calling and live broadcasting over Bluetooth mesh, without internet (Open source)

说明与用途

MeshLive 是一款开源 Android 应用，允许通过蓝牙 Mesh 在没有互联网的情况下进行视频通话和直播，利用附近的手机作为中继。

问题

Mobile internet shutdowns and restricted communication during protests in Delhi limited students’ ability to communicate beyond text.

结果

MeshLive demonstrates that live video and voice communication can be achieved over Bluetooth mesh without internet, though performance is limited by bandwidth and device compatibility.

工作流

• 1. Install MeshLive on nearby Android phones.
• 2. Use the app to start a live camera/microphone broadcast or a two‑way voice/video call.
• 3. Phones within Bluetooth range forward the broadcast (multi‑hop relaying) to extend reach.
• 4. Devices receive and display the video/audio streams locally.
• 5. Optional experimental offline messaging can be sent between devices.

Live camera and microphone broadcasting over Bluetooth

Multi-hop relaying, where nearby phones can forward a broadcast beyond the original sender's range

来源

Video can be laggy, some phone combinations don't work properly, and several features are still experimental or insufficiently tested
