Perguntas frequentes
Do you need my physical IoT/BLE device to develop the app?
In most cases, yes. Having the physical hardware is highly recommended to accurately test BLE pairing, read/write GATT characteristics, and debug real-time data. If shipping the device is not possible, we can work using detailed BLE protocol documentation and remote simulators.
Can you build a custom BLE SDK for my hardware?
Yes! In addition to mobile apps, I can develop a custom, reusable iOS and Android SDK (framework) for your IoT device. This allows your business to distribute the SDK so other developers can easily integrate your hardware into their own apps.
What kind of Bluetooth and IoT devices can you connect to?
With 10+ years of experience, I can connect apps to almost any BLE-enabled hardware. This includes medical devices (ECGs, BP monitors, weight scales, Activity trackers, pulse-oximeters), smart home sensors, fitness wearables, beacons, and custom ESP32, Raspberry Pi, or Arduino boards.
Do you build native or cross-platform IoT apps?
I offer both! For maximum Bluetooth performance and reliable background syncing, native apps (Swift for iOS, Kotlin for Android) are best. However, if you want to save time and budget, I can build high-quality cross-platform BLE apps using Flutter or React Native.
Can the app sync Bluetooth data in the background?
Yes. I specialize in implementing advanced background state restoration and BLE background processing. This ensures your app securely continues to scan, connect, and collect sensor data even when the user's phone is locked or the app is minimized.
