The parts of an app where every platform does it differently and the documentation assumes you already know. Each library owns the native code, the permissions and the background rules, and gives you one API across iOS, Android, Windows, macOS and beyond.
Scan, connect and talk to BLE peripherals — reactive and async
A unified API for the Bluetooth LE central role: scanning, connecting and talking to peripherals. It wraps each platform's native BLE stack and gives you a consistent reactive and async experience.
Turn your device into a BLE peripheral with custom GATT services
Let your app act as a BLE peripheral: advertise services, host GATT services with characteristics, and talk to the central devices that connect to you.
SignalR style hubs between nearby devices over Bluetooth LE
One device hosts a hub and nearby devices connect and call it through a source generated, strongly typed proxy. The host pushes events to everyone, one client or a group - no server or network required.
BluetoothLE Hubs over Wi-Fi as well as Bluetooth LE
Write the hub once and serve it over Bluetooth LE and Wi-Fi at the same time. Clients discover hosts over BLE and mDNS in one list, connect over Wi-Fi when they can and fall back to BLE, and share the same hub, groups and pushes.
iBeacon and Eddystone — ranging, region monitoring and broadcasting
Both beacon formats that matter — Apple's iBeacon and Google's Eddystone. Range for proximity in the foreground, monitor regions in the background, or broadcast as a beacon yourself.
Talk to vehicles through OBD-II adapters
Communicate with vehicles through OBD-II adapters using a command-object pattern with typed results, pluggable transports and adapter auto-detection.
Foreground and background GPS tracking
IGpsManager routed to whatever each OS actually offers, in the foreground or the background.
Geofencing with dwell, and unlimited region geofencing
IGeofenceManager over the native geofencing engine on each OS, sharing persistence and an access model with GPS, and working in the background.
CLMonitorTurn coordinates into addresses
Reverse geocode a position into placemarks with the platform geocoder — no API key — or OpenStreetMap Nominatim.
Know whether the user is walking, running, driving or still
Observe the activity the device reports — walking, running, cycling, driving or stationary — as plain .NET events.
Find things on the local network and advertise your own
Discover printers, casting targets, IoT devices, ONVIF cameras and other instances of your app — and publish your own services — across the three protocols that matter.
Scan, join and manage Wi-Fi networks, and host a hotspot
Scan for access points in range, join and leave networks, manage the ones the device has saved, watch the current network's SSID, signal, IP and DNS, and host a hotspot.
Drive the OS's built-in IKEv2 VPN client from your app
Install your IKEv2 VPN profile on the device, connect and disconnect it from code, and watch whether it is up - using the client the operating system already ships.
Talk to your Apple Watch or Wear OS companion app
One API over WatchConnectivity and the Wear OS Data Layer: live messages with replies, shared context, queued transfers and files, delivered to a delegate even when the app is in the background.
Record the screen to MP4, with microphone and system audio
Capture the screen with each platform's native recorder, with the microphone and the device's own audio mixed in where the OS allows it.
Read game controllers, with rumble, battery, motion and light bars
Sticks, triggers and buttons from one API on every platform, named by position so "A" is the bottom face button on an Xbox, PlayStation and Nintendo pad alike.
Achievements, leaderboards and friends over Game Center and Play Games
One set of keys for Apple Game Center and Google Play Games Services, with progress queued on the device so an offline or signed-out player never loses an unlock.
Receipt printers over BLE, WiFi and the browser, plus OS-native printing
Build a receipt once as a PrintDocument and stream it as ESC/POS to a thermal printer over Bluetooth LE, TCP or the browser - or hand a PDF, image or HTML to AirPrint, Android, Windows or CUPS for any installed printer.
