1

Copy This Code

Replace your ViewController.swift with:
import UIKit
import omi_lib

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.lookForDevice()
    }

    func lookForDevice() {
        OmiManager.startScan { device, error in
            print("starting scan")
            if let device = device {
                print("got device ", device)
                self.connectToOmiDevice(device: device)
                OmiManager.endScan()
            }
        }
    }

    func connectToOmiDevice(device: Device) {
        OmiManager.connectToDevice(device: device)
        self.listenToLiveTranscript(device: device)
        self.reconnectIfDisconnects()
    }

    func reconnectIfDisconnects() {
        OmiManager.connectionUpdated { connected in
            if connected == false {
                self.lookForDevice()
            }
        }
    }

    func listenToLiveTranscript(device: Device) {
        OmiManager.getLiveTranscription(device: device) { transcription in
            print("transcription:", transcription ?? "no transcription")
        }
    }
}

API Reference

The OmiManager class provides all device interaction methods:

​
Device Scanning

import omi_lib

// Scan for any Omi device
func lookForDevice() {
    OmiManager.startScan { device, error in
        if let device = device {
            print("got device ", device)
            self.connectToOmiDevice(device: device)
            OmiManager.endScan()
        }
    }
}

// Scan for a specific device
func lookForSpecificDevice(device_id: String) {
    OmiManager.startScan { device, error in
        if let device = device, device.id == "some_device_id" {
            print("got device ", device)
            self.connectToOmiDevice(device: device)
            OmiManager.endScan()
        }
    }
}

​
Connection Management

func connectToOmiDevice(device: Device) {
    OmiManager.connectToDevice(device: device)
    self.reconnectIfDisconnects()
}

func reconnectIfDisconnects() {
    OmiManager.connectionUpdated { connected in
        if connected == false {
            self.lookForDevice()
        }
    }
}

​
Live Data

func listenToLiveTranscript(device: Device) {
    OmiManager.getLiveTranscription(device: device) { transcription in
        print("transcription:", transcription ?? "no transcription")
    }
}

​
