Hardware Integration

​

Recommended Flow

1. Ask the user which glasses model they are pairing.
2. Call scan() for that model.
3. Present typed discovered devices from the progressive scan results.
4. Connect using the discovered device or default-device helper.
5. Read shaped glasses state, firmware fields, and hardware-related status before enabling advanced features.
6. Keep app UI derived from SDK status rather than from command success alone.

import BluetoothSdk, {DeviceModels} from '@mentra/bluetooth-sdk';

const devices = await BluetoothSdk.scan(DeviceModels.MentraLive, {
  timeoutMs: 10_000,
  onResults: (nextDevices) => renderDevicePicker(nextDevices),
});

await BluetoothSdk.connect(await chooseDevice(devices));

var selectedDevice: Device? = null
sdk.scan(DeviceModel.MENTRA_LIVE, timeoutMs = 10_000) { nextDevices ->
    renderDevicePicker(nextDevices, onSelect = { selectedDevice = it })
}

selectedDevice?.let { sdk.connect(it) }

var selectedDevice: Device? = nil
try sdk.scan(model: .mentraLive, timeout: 10) { nextDevices in
    renderDevicePicker(nextDevices) { device in
        selectedDevice = device
    }
}

if let selectedDevice {
    try sdk.connect(to: selectedDevice)
}

Connection Resilience

• Subscribe to status callbacks before connecting.
• Retry scans manually from the UI instead of scanning forever in the background.
• On mobile OS background transitions, expect Bluetooth behavior to vary by platform.
• Provide a visible “forget device” path that clears both the SDK default device and any app-persisted default-device record.
• If your app persists a default device, restore it with setDefaultDevice() before calling connectDefault().
