Device Integration — Wearables, Bluetooth Devices & Health Stores

This section explains how to integrate health data sources with vitalera — from consumer wearables like Garmin and Fitbit (cloud API) to clinical Bluetooth devices like blood pressure monitors and glucometers (SDK).

Consumer Wearables (API-Based)​

Connect popular consumer wearables via server-to-server API integrations. No mobile SDK required for these — users link their accounts once via OAuth, and data flows automatically.

General Workflow​

For all BLE devices, the integration follows three steps:

1. Discover​

Scan for nearby BLE devices using DiscoveryFilter to filter by provider, capability, or device name:

// Android (Kotlin)
val filter = DiscoveryFilter(
    capabilities = setOf(DeviceCapability.BLOOD_PRESSURE)
)
sdk.devices.discover(filter, timeoutMs = 15_000L).collect { descriptor ->
    println("Found: ${descriptor.name} (${descriptor.provider})")
}
// iOS (Swift)
let filter = DiscoveryFilter(
    providers: nil,
    capabilities: [DeviceCapability.bloodPressure],
    namePrefix: nil
)
for try await descriptor in sdk.devices.discover(filter: filter, timeoutMs: 15_000) {
    print("Found: \(descriptor.name) (\(descriptor.provider))")
}

2. Connect​

Create a device from the discovered descriptor and connect:

// Android
val device = sdk.devices.createDevice(descriptor)
device.connect(timeoutMs = 10_000L)
// iOS
let device = sdk.devices.createDevice(descriptor: descriptor)
try await device.connect(timeoutMs: 10_000)

3. Collect​

Read typed observations from the connected device:

// Android
device.collect().collect { observation ->
    when (observation) {
        is BloodPressureObservation ->
            println("BP: ${observation.systolic}/${observation.diastolic}")
        is HeartRateObservation ->
            println("HR: ${observation.heartRate} bpm")
    }
}
device.disconnect()
// iOS
for try await observation in device.collect() {
    if let bp = observation as? BloodPressureObservation {
        print("BP: \(bp.systolic)/\(bp.diastolic) mmHg")
    } else if let hr = observation as? HeartRateObservation {
        print("HR: \(hr.heartRate) bpm")
    }
}
try await device.disconnect()

Device-Specific Notes​

Blood Pressure Monitors​

  • Beurer BM85: Ensure the device is charged and turned off before scanning. Turn on the device after scanning starts and wait for Bluetooth discovery.
  • Lifevit BPM 160/260: Turn on the device, then start scanning. Once connected, call read and wait for the observation.
  • Omron Evolv (HEM-7600T): Turn on the device and start scanning. The SDK handles pairing automatically.

Pulse Oximeters​

  • Lifevit OL750 / Beurer PO60: Place your finger in the oximeter and turn it on, then start scanning. Data streams continuously until you disconnect.

Thermometers​

  • Lifevit IT45B / Omron MC-280B: Turn on the thermometer, start scanning, and take a measurement. The observation is returned after the reading completes.

Scales​

  • Lifevit BL2000: Step on the scale when prompted. The weight observation is returned once the reading stabilizes.

Glucometers​

  • Contour Next: The device must be pre-paired via system Bluetooth settings before scanning from the SDK.

Heart Rate Sensors​

  • Polar H10: Wear the chest strap, start scanning, and the SDK streams heart rate data continuously.
