The Way to Success: Find the Right BLE App Developer

Short: You have a brilliant idea for a connected product that uses Bluetooth Low Energy (BLE).

You have a brilliant idea for a connected product that uses Bluetooth Low Energy (BLE). The potential markets are huge, the technology is promising.

But the success of your project stands and falls with a decisive point. The choice of the right development partner.

The development of BLE applications is a complex discipline that goes far beyond the pure app programming. It requires deep knowledge in hardware, firmware and software.

In this guide, we will give you a checklist that will help you to separate the wheat and find the ideal partner for your IoT project.

Checklist: What to pay attention to when choosing

A checklist with the most important criteria for selecting the right BLE app developer or a expert app agency for your IoT project.

Take the time to evaluate potential service providers using the following criteria. A good partner will be able to give you clear information on all these points.

Reproven BLE expertise & references Do not only ask if the agency can develop apps. Ask for completed BLE projects.

Let references show and, if possible, introduce the built apps in the App Store. Are there case studies that describe the process and results?

Good technology understanding (hardware, firmware, app) A pure app developer will quickly reach its limits in a BLE project. The ideal partner understands the entire stack.

It can advise you when selecting the right BLE module, understand firmware developers and know how to implement stable and performant connections in the mobile app.

Find a team that combines embedded developers and app developers under one roof.

Expertise in native app development (iOS & Android) For a performant and reliable BLE communication, native development with the frameworks provided by Apple (Swift) and Google (Kotlin) (CoreBluetooth and Android BLE API) is usually the best choice.

Be skeptical with pure cross-platform solutions, as they can often compromise the stability of the Bluetooth connection.

Experience with regulatory needs Do you develop a medical device?

Your partner must then know the needs of Medical Device Regulation (MDR) and IEC 62304 standards for software life cycles.

There are also specific needs for other sectors such as the industry (e.g. ATEX) or the US market (FCC), whose ignorance can make a project fail.

Transparent process and agile methods A complex IoT project can rarely be
