GATT, pairing & streaming

Bluetooth Low Energy that connects and stays connected.

GATT services on the firmware side, and reliable pairing, reconnect and data streaming in the app. Both halves built to fit, so your BLE device links cleanly and holds it. Software-only, to your hardware spec.

The BLE problem

Bluetooth that pairs on the third try and drops on the second minute.

A GATT profile that does not match the app, no reconnection logic, streaming that stalls. BLE is fiddly, and done casually it becomes the most-complained-about part of the product.

Flaky pairing

Connections that take several attempts.

No reconnect

Drops that need a full re-pair.

Stalled streams

Data that freezes mid-session.

Common questions

BLE software, answered.

What is BLE device software?

The software on both sides of a Bluetooth Low Energy link: GATT services and characteristics on the device firmware, and pairing, reconnect and data streaming in the companion app.

Do you handle both firmware and app sides?

Yes. We define the GATT profile on the firmware and build the matching app connectivity, so the two sides fit.

How do you make BLE reliable?

With careful connection handling, reconnection logic, buffering and testing on your hardware, so the link holds in real use.

Can BLE carry firmware updates?

Yes. We can build a BLE-based over-the-air update path, working with your firmware's update mechanism.

Do you design the hardware?

No. Software-only. We write BLE software to your hardware team's specification. See also embedded software.
