• Connect/disconnect RuuviTag
• Read RuuviTag logs
• RuuviTag logging in background (firmware 3.27.2+)

Requirements

• iOS 10.0+

Installation

CocoaPods

You can use CocoaPods to install BTKit by adding it to your Podfile:

platform :ios, '10.0'
use_frameworks!
pod 'BTKit'

Swift Package Manager

You can add link to this repo in XCode/File/Swift Packages/Add Package Dependency...

Usage example

To make it work import BTKit

import BTKit

Check for iPhone/iPad Bluetooth state

view.isBluetoothEnabled = scanner.bluetoothState == .poweredOn

BTForeground.shared.state(self, closure: { (observer, state) in
    observer.view.isBluetoothEnabled = state == .poweredOn
})

Listen to advertisements in foreground

BTForeground.shared.scan(self) { (observer, device) in
                             if let ruuviTag = device.ruuvi?.tag {
                                 print(ruuviTag)
                             }
                         }

Determine if device is out of range or went offline

BTForeground.shared.lost(self, options: [.lostDeviceDelay(10)], closure: { (observer, device) in
    if let ruuviTag = device.ruuvi?.tag {
        print("Ruuvi Tag is offline or went out of range")
    }
})

Observe specific device advertisements

BTForeground.shared.observe(self, uuid: ruuviTag.uuid, options: [.callbackQueue(.untouch)]) { (observer, device) in
    print("Specific RuuviTag is advertising")
}

Connect to specific device

if ruuviTag.isConnectable {
    ruuviTag.connect(for: self, options: [.connectionTimeout(10)],  connected: { observer, result in
        switch result {
        case .just:
            print("just connected")
        case .already:
            print("was already connected")
        case .disconnected:
            print("just disconnected")
        case .failure(let error):
            print(error.localizedDescription)
        }
    }, heartbeat: { observer, device in
        if let ruuviTag = device.ruuvi?.tag {
            print(ruuviTag)
        }
    }, disconnected: { observer, result in
        switch result {
        case .just:
            print("just disconnected")
        case .already:
            print("disconnected")
        case .stillConnected:
            print("still connected because of other callers")
        case .failure(let error):
            print(error.localizedDescription)
        }
    })
}

or use uuid

BTBackground.shared.connect(for: self, options: [.connectionTimeout(10)],  connected: { observer, result in
    switch result {
    case .just:
        print("just connected")
    case .already:
        print("was already connected")
    case .disconnected:
        print("just disconnected")
    case .failure(let error):
        print(error.localizedDescription)
    }
}, heartbeat: { observer, device in
    if let ruuviTag = device.ruuvi?.tag {
        print(ruuviTag)
    }
}, disconnected: { observer, result in
    switch result {
    case .just:
        print("just disconnected")
    case .already:
        print("disconnected")
    case .stillConnected:
        print("still connected because of other callers")
    case .failure(let error):
        print(error.localizedDescription)
    }
})
}

Read temperature, humidity, pressure logs from the connectable device

if let from = Calendar.current.date(byAdding: .minute, value: -5, to: Date()) {
    ruuviTag.celisus(for: self, from: from) { (observer, result) in
        switch result {
        case .success(let values):
            print(values)
        case .failure(let error):
            print(error.localizedDescription)
        }
    }
    ruuviTag.humidity(for: self, from: from) { (observer, result) in
        switch result {
        case .success(let values):
            print(values)   
        case .failure(let error):
            print(error.localizedDescription)
        }
    }
    ruuviTag.pressure(for: self, from: from) { (observer, result) in
        switch result {
        case .success(let values):
            print(values)
        case .failure(let error):
            print(error.localizedDescription)
        }
    }
}

or use BTKit if you know only the uuid:

BTBackground.shared.services.ruuvi.nus.celisus(for: self, uuid: ruuviTag.uuid, from: from, result: { (observer, result) in
    switch result {
    case .success(let values):
        print(values)
    case .failure(let error):
        print(error.localizedDescription)
    }
})

BTBackground.shared.services.ruuvi.nus.humidity(for: self, uuid: ruuviTag.uuid, from: from, result: { (observer, result) in
    switch result {
    case .success(let values):
        print(values)
    case .failure(let error):
        print(error.localizedDescription)
    }
})

BTBackground.shared.services.ruuvi.nus.pressure(for: self, uuid: ruuviTag.uuid, from: from, result: { (observer, result) in
    switch result {
    case .success(let values):
        print(values)
    case .failure(let error):
        print(error.localizedDescription)
    }
})

Read full log in one batch

if let from = Calendar.current.date(byAdding: .minute, value: -5, to: Date()) {
    ruuviTag.log(for: self, from: from) { (observer, result) in
        switch result {
        case .success(let logs):
            print(logs)
        case .failure(let error):
            print(error.localizedDescription)
        }
    }
}

Or use BTKit if you know only the uuid

BTBackground.shared.services.ruuvi.nus.log(for: self, uuid: ruuviTag.uuid, from: from, result: { (observer, result) in
    switch result {
    case .success(let logs):
        print(logs)
    case .failure(let error):
        print(error.localizedDescription)
    }
})

Disconnect from the device

ruuviTag.disconnect(for: self) { (observer, result) in
    switch result {
    case .just:
        observer.isConnected = false
    case .already:
        observer.isConnected = false
    case .stillConnected:
        observer.isConnected = true
    case .failure(let error):
        observer.isConnected = false
        print(error.localizedDescription)
    }
}

or use BTKit if you know only uuid

BTBackground.shared.disconnect(for: self, uuid: ruuviTag.uuid) { (observer, result) in
    switch result {
    case .just:
        observer.isConnected = false
    case .already:
        observer.isConnected = false
    case .stillConnected:
        observer.isConnected = true
    case .failure(let error):
        observer.isConnected = false
        print(error.localizedDescription)
    }
}
