About the Nearby Project
Nearby Connection
Nearby Connections is a high level protocol on top of Bluetooth/WiFi that acts as a medium-agnostic socket. Devices are able to advertise, scan, and connect with one another over any shared medium (eg. BT <-> BT). Once connected, the two devices share a list of all supported mediums and attempt to upgrade to the one with the highest bandwidth (eg. BT -> WiFi). The connection is encrypted, reliable, and fully duplex. BYTE, FILE, and STREAM payloads are all supported and will be chunked & transferred internally and recombined on the receiving device. See Nearby Connections Overview for more information.

Building Nearby, Unit Testing and Sample Apps
We support multiple platforms including Linux, iOS & Windows.
Building for Linux
Currently we support building from source using [bazel] (https://bazel.build). Other BUILD system such as cmake may be added later.
Prerequisites:
- Bazel
- clang with support for c++ 17+
- Openssl libcrypto.so (-lssl;-lcrypto).
To build the Nearby Connection Core library:
CC=clang CXX=clang++ bazel build -s --check_visibility=false //connections:core --spawn_strategy=standalone --verbose_failures
Building for macOS and iOS
Currently we support building with Swift Package Manager.
Prerequisites:
- Xcode. Available from Apple Store.
- Google Protobuf Compiler (protoc). If you have homebrew installed, you can do
brew install protobuf.
To build the Nearby Connection library:
swift build
We also provide a iOS [sample app using the Nearby Connections library] (https://github.com/google/nearby/blob/master/internal/platform/implementation/ios/Example/NearbyConnectionsExample/README.md).
Limitation
The only Medium supported is Wifi LAN.
