Problem
The Android emulator has a virtual Bluetooth controller but no way to reach real hardware. The usual workarounds are a USB dongle passed through to the emulator, or a library compiled into the app that only exists for testing.
Activev0.3.1
MacPhone
Real Bluetooth LE devices in the Android emulator on your Mac.
MacPhone connects to a Bluetooth LE device over the Mac's built-in radio and publishes it inside the Android emulator. The app you are testing scans, connects, reads, writes and subscribes as it would on a phone, with no USB dongle and no change to its code. The same window runs your Android emulators and Xcode simulators.

What I built
A SwiftUI app that acts as a CoreBluetooth central, reads the device's GATT table and hands it over a token-protected localhost socket to a Bumble process. That process publishes the same services, name and manufacturer data on netsim, the emulator's controller, and forwards every read, write and notification to the real device.
Highlights
- Real BLE devices in the Android emulator, through the Mac's own Bluetooth, no dongle.
- The app under test uses the normal Android Bluetooth API. No extra library.
- Reads, writes and notifications both ways; subscriptions survive a reconnect.
- Create, run and manage Android emulators (Android 14 to 17) and Xcode simulators for every Apple platform.
- Install apps by drag and drop, open URLs, take screenshots, switch light and dark mode.
- Limits: Bluetooth LE only, no devices that need Bluetooth pairing, no Bluetooth in the iOS Simulator.
