        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")
        }
    }

    func listenToLiveAudio(device: Device) {
        OmiManager.getLiveAudio(device: device) { file_url in
            print("file_url: ", file_url?.absoluteString ?? "no url")
        }
    }
}
  1. Select your team, connect the phone (we suggest via cable), and run the project
  2. turn on omi device - the app should connect automatically
Speak. You will not see any UI on the mobile app, but you should see transcription in logs. Transcription runs locally using whisper CleanShot 2025-03-25 at 16 00 43@2x

Other Usage

The core interface for interacting with the Omi device is the OmiManager.swift. The OmiManager abstracts things like scanning, connecting, and reading bluetooth data into a few simple function calls. Looking for a device 
import omi_lib

func lookForDevice() {
    OmiManager.startScan { device, error in
        // connect to first found omi device
        if let device = device {
            print("got device ", device)
            self.connectToOmiDevice(device: device)
            OmiManager.endScan()
        }
    }
}

func lookForSpecificDevice(device_id: String) {
    OmiManager.startScan { device, error in
        // connect to first found omi device
        if let device = device, device.id == "some_device_id" {
            print("got device ", device)
            self.connectToOmiDevice(device: device)
            OmiManager.endScan()
        }
    }
}
Connecting / Reconnecting to a device 
func connectToOmiDevice(device: Device) {
    OmiManager.connectToDevice(device: device)
    self.reconnectIfDisconnects()
}

func reconnectIfDisconnects() {
    OmiManager.connectionUpdated { connected in
        if connected == false {
            self.lookForDevice()
        }
    }
}
Getting Live Data 
func listenToLiveTranscript(device: Device) {
    OmiManager.getLiveTranscription(device: device) { transcription in
        print("transcription:", transcription ?? "no transcription")
    }
}

func listenToLiveAudio(device: Device) {
    OmiManager.getLiveAudio(device: device) { file_url in
        print("file_url: ", file_url?.absoluteString ?? "no url")
    }
}
