netguru / Blueswift

Easy to use Bluetooth open source library brought to you by Netguru.
🤟 Probably the easiest way to interact with bluetooth peripherals 🤟

🤹🏻‍♂️ Features

• [x] Handles connection with remote peripherals.
• [x] Handles advertising an iPhone as Bluetooth LE peripheral.
• [x] Closure based read/write/notify requests.
• [x] Built in data conversion method with Command wrapper.

📲 Connection:

Below you can find an easy code sample to connect to the peripheral.
Really thats all that is needed 🍾🍾

let connection = BluetoothConnection.shared
let characteristic = try! Characteristic(uuid: "your_characteristic_uuid", shouldObserveNotification: true)
let service = try! Service(uuid: "your_service_uuid", characteristics: [characteristic])
let configuration = try! Configuration(services: [service], advertisement: "your_advertising_uuid")
let peripheral = Peripheral(configuration: configuration)
connection.connect(peripheral) { error in
	// do awesome stuff
}

📡 Advertisement:

Below you can find a code sample the setup the iPhone to advertise Bluetooth.
That's all it takes to advertise one service containing one characteristic.

let characteristic = try! Characteristic(uuid: "your_characteristic_uuid")
let service = try! Service(uuid: "your_service_uuid", characteristics: [characteristic])
let configuration = try! Configuration(services: [service], advertisement: "your_service_uuid")
let peripheral = Peripheral(configuration: configuration, advertisementData: [.localName("Test"), .servicesUUIDs("your_service_uuid")])
advertisement.advertise(peripheral: peripheral) { error in
	// oh no, something failed in that case          
}

📟 📲 Data transfer:

Of course data transfer is also possible, both for advertising and connection mode! Below there are some basic examples, for more please see More usage section 👇🏻

Connection mode:

let command = Command.utf8String("Hello world")
peripheral.write(command: command, characteristic: someCharacteristic, handler: { error in
	// written!
})
peripheral.read(characteristic, handler: { data, error in
	// read!
})

Advertisement mode:

let command = Command.int8(3)
advertisement.update(command, characteristic: characteristic) { error in
	// data updated!
}
advertisement.writeRequestCallback = { characteristic, data in
	// written!
}

Also feel free to check example project bundled with this repository! 👩🏼‍🏫 👨🏼‍🏫 It's a complete app that allows connection and sending text messages between two iPhones.

BlueSwift can be drag'n dropped to the project directory,
but what's more important it's supported by most common dependency management!

Just drop the line below to your Podfile:

pod 'BlueSwift'
