BluetoothLE Hubs Release Notes

v1

1.0 - TBD

Feature

Initial release - SignalR style hubs over Bluetooth LE. A [BleHubClient] interface describes the hub: its methods (Task, Task<T>, IAsyncEnumerable<T>) are client to host calls and its Action events are host to client pushes

Feature

Source generator emits the client proxy, the hub dispatcher, typed pushes (Clients.All.StateChanged(state)) and an IHubContext<THub>.Clients extension property - AOT and trim safe, no reflection, with SBH001-SBH006 diagnostics

Feature

BleHub<TContract> with Context, Clients (All, Others, Caller, Client, Group…), Groups, OnConnectedAsync / OnDisconnectedAsync and Context.Abort()

Feature

IHubContext<THub> to push, disconnect clients and start / stop a single hub from outside a hub - shared GATT services stay up while any of their hubs runs and advertising follows the running hubs

Feature

Generated client proxies with discovery, MTU negotiation, timeouts, cancellation that reaches the hub, ordered push delivery and shared BLE connections across hub clients

Feature

L2CAP file transfers - UploadFile, UploadStream and DownloadFile on the client, a directory backed or custom (IBleHubFileHandler) server on the host
