IoT AND CONNECTED DEVICES

Connect your device to a useful app.

We build companion apps for connected hardware, including BLE, Matter, and Wi-Fi pairing. The work covers device control, firmware communication, synchronization, and updates.

IoT companion apps: scope of work.

We agree on the deliverables for your project. These are the areas we can help with.

Device pairing & onboarding

We design and test BLE, Wi-Fi, and Matter setup flows so users can connect and configure their devices.

Reliable connectivity

We implement reconnection, state synchronization, and recovery when a wireless connection drops.

Firmware bridges

We define and implement the app-to-device protocol, with versioning to support different firmware releases.

OTA updates

We implement over-the-air firmware updates with a rollback path so released devices can receive fixes and improvements.

Companion app

We build device controls, monitoring, automation, and notifications around what the hardware can do.

Cloud & fleet

Where needed, we add cloud control, telemetry, and fleet management for groups of devices.

$ ./build --steps

How we approach the work.

We plan the scope with you and review progress together as the work develops.

  1. Protocol & constraints

    We agree on the device protocol, connection method, and hardware constraints.

  2. Pairing prototype

    We test pairing and reconnection early to identify problems before developing the rest of the app.

  3. App + bridge

    We develop the companion app and its firmware integration together.

  4. Field testing

    We test different distances, sources of interference, and firmware versions.

  5. Launch & OTA

    We prepare the release and verify over-the-air updates so devices can be maintained after launch.

Questions, answered.

We define the protocol between the app and device together with your team. We coordinate app development and firmware integration so both sides can be tested as the product develops.

We look at power use, range, data needs, and the ecosystem the device must work with. We use BLE for local communication with low power use and Wi-Fi where more bandwidth is needed. For smart-home products, we also consider Matter compatibility.

Yes. We work on over-the-air firmware updates and rollback, so devices can receive fixes after they reach users. The update and recovery approach needs to fit the device’s hardware and firmware.

Yes. We can add cloud control, telemetry, and fleet management so you can monitor and update devices in use.
