Package gatt provides a Bluetooth Low Energy gatt implementation. Gatt (Generic Attribute Profile) is the protocol used to write BLE peripherals (servers) and centrals (clients). This package is a work in progress. The API will change. As a peripheral, you can create services, characteristics, and descriptors, advertise, accept connections, and handle requests. As a central, you can scan, connect, discover services, and make requests. gatt supports both Linux and OS X. On Linux: To gain complete and exclusive control of the HCI device, gatt uses HCI_CHANNEL_USER (introduced in Linux v3.14) instead of HCI_CHANNEL_RAW. Those who must use an older kernel may patch in these relevant commits from Marcel Holtmann: Note that because gatt uses HCI_CHANNEL_USER, once gatt has opened the device no other program may access it. Before starting a gatt program, make sure that your BLE device is down: If you have BlueZ 5.14+ (or aren't sure), stop the built-in bluetooth server, which interferes with gatt, e.g.: Because gatt programs administer network devices, they must either be run as root, or be granted appropriate capabilities: USAGE See the server.go, discoverer.go, and explorer.go in the examples/ directory for writing server or client programs that run on Linux and OS X. Users, especially on Linux platforms, seeking finer-grained control over the devices can see the examples/server_lnx.go for the usage of Option, which are platform specific. See the rest of the docs for other options and finer-grained control. Note that some BLE central devices, particularly iOS, may aggressively cache results from previous connections. If you change your services or characteristics, you may need to reboot the other device to pick up the changes. This is a common source of confusion and apparent bugs. For an OS X central, see http://stackoverflow.com/questions/20553957. gatt started life as a port of bleno, to which it is indebted: https://github.com/sandeepmistry/bleno. If you are having problems with gatt, particularly around installation, issues filed with bleno might also be helpful references. To try out your GATT server, it is useful to experiment with a generic BLE client. LightBlue is a good choice. It is available free for both iOS and OS X.

Package gatt provides a Bluetooth Low Energy gatt implementation. Gatt (Generic Attribute Profile) is the protocol used to write BLE peripherals (servers) and centrals (clients). This package is a work in progress. The API will change. As a peripheral, you can create services, characteristics, and descriptors, advertise, accept connections, and handle requests. As a central, you can scan, connect, discover services, and make requests. gatt supports both Linux and OS X. On Linux: To gain complete and exclusive control of the HCI device, gatt uses HCI_CHANNEL_USER (introduced in Linux v3.14) instead of HCI_CHANNEL_RAW. Those who must use an older kernel may patch in these relevant commits from Marcel Holtmann: Note that because gatt uses HCI_CHANNEL_USER, once gatt has opened the device no other program may access it. Before starting a gatt program, make sure that your BLE device is down: If you have BlueZ 5.14+ (or aren't sure), stop the built-in bluetooth server, which interferes with gatt, e.g.: Because gatt programs administer network devices, they must either be run as root, or be granted appropriate capabilities: USAGE See the server.go, discoverer.go, and explorer.go in the examples/ directory for writing server or client programs that run on Linux and OS X. Users, especially on Linux platforms, seeking finer-grained control over the devices can see the examples/server_lnx.go for the usage of Option, which are platform specific.

Package fx is the UberFx Service Framework. UberFx is a flexible, modularized framework for building robust and performant services. It takes care of the boilerplate code and lets you focus on your application logic. Beta. Expect minor API changes and bug fixes. See our changelog (CHANGELOG.md)for more. UberFx builds the following into your service: • Logging backed by the zap logger • Configuration provider that seamlessly merges static and dynamic config • Application-level as well as runtime metrics for effective monitoring • Request tracing for application-level instrumentation • Context-aware logging for easy debugging • RPC module with Thrift interfaces for microservices • HTTP module with intelligent defaults for web applications • Task module for executing async tasks durably To get a feel for what an UberFx service looks like, see our examples (examples/). A service is a container for a set of **modules** and controls their lifecycle. A service can have any number of modules, each responsible for a specific type of functionality, such as a Kafka message ingestion, exposing an HTTP server, or a set of RPC service endpoints. The core service is responsible for loading basic configuration and starting and stopping a set of these modules. Each module gets a reference to the service to access standard values such as the service name or basic configuration. Read more about the service model (service/README.md) The top-level packages contain the nuts and bolts useful for a fully-fledged service. That said, none (except for service) requires an instance or even the idea of a service. You can use the packages independently. If, for example, you only want use the configuration logic from UberFx, you can import go.uber.org/fx/config and use it in a standalone CLI app. The service package contains logic specific to a running service. configis separate from service. A modules is a pluggable component that provides an encapsulated set of functionality, and all modules are managed by the service. Implemented modules: • HTTP server • TChannel server • Async task execution Planned modules: • Kafka ingester • Delayed jobs You give your modules named keys for the purpose of looking up their configuration. This naming is arbitrary and only needs to be unique across modules. We do this because it's possible for a service to have multiple modules of the same type, such as multiple Kafka ingesters. In this example, a module named: "yarpc" would look up its advertise name as modules.yarpc.advertiseName. UberFx exposes a simple, consistent way to track metrics and is built on top of Tally (https://github.com/uber-go/tally). Internally, this uses a pluggable mechanism for reporting these values, so they can be reported to M3, logging, etc., at the service owner's discretion. By default, the metrics are not reported (using a tally.NoopScope). UberFx introduces a simplified configuration model that provides a consistent interface to configuration from pluggable configuration sources. This interface defines methods for accessing values directly or into strongly typed structs. Read more about configuration. (config/README.md) UberFx is compatible with Go 1.7 and above.

Package gatt provides a Bluetooth Low Energy gatt implementation. Gatt (Generic Attribute Profile) is the protocol used to write BLE peripherals (servers) and centrals (clients). This package is a work in progress. The API will change. As a peripheral, you can create services, characteristics, and descriptors, advertise, accept connections, and handle requests. As a central, you can scan, connect, discover services, and make requests. gatt supports both Linux and OS X. On Linux: To gain complete and exclusive control of the HCI device, gatt uses HCI_CHANNEL_USER (introduced in Linux v3.14) instead of HCI_CHANNEL_RAW. Those who must use an older kernel may patch in these relevant commits from Marcel Holtmann: Note that because gatt uses HCI_CHANNEL_USER, once gatt has opened the device no other program may access it. Before starting a gatt program, make sure that your BLE device is down: If you have BlueZ 5.14+ (or aren't sure), stop the built-in bluetooth server, which interferes with gatt, e.g.: Because gatt programs administer network devices, they must either be run as root, or be granted appropriate capabilities: USAGE See the server.go, discoverer.go, and explorer.go in the examples/ directory for writing server or client programs that run on Linux and OS X. Users, especially on Linux platforms, seeking finer-grained control over the devices can see the examples/server_lnx.go for the usage of Option, which are platform specific.
