Bluetooth Low Energy (BLE) Jobs
Bluetooth Low Energy (BLE) is a powerful and energy-efficient technology and a core component of digital transformation in the Internet of Things (IoT). A Bluetooth Low Energy Developer can help businesses integrate BLE into their devices and systems to gain new insights and control, streamline operations, and provide a better customer experience.
BLE is used in a variety of applications today, such as wearables and home automation, and its range is increasing rapidly across truly connected devices that require secure communication. BLE works by Bluetooth classic radio technology transferring data between two devices using radio waves within the 2.4GHz range. This technology allows robust communication over longer distances than most other wireless technologies with just a fraction of the power required to transmit the data.
Here’s some projects that our expert Bluetooth Low Energy Developers have made real:
- Building an entire ecosystem allowing for secure custodial wallets with Bluetooth device connection
- Developing advanced fall detectors on NRF 52832 Chipset
- Implementing and integrating BLE functionality for device configuration on ESP32-S3
- Establishing Flutter plugins for ACR1255U-J1 Bluetooth NFC Reader
- Creating prototypes with Embedded C and ARM Cortex M
- Developing secure interconnectivity between python TCP sockets and BLE devices
- Constructing Raspberry 3/4 Bluetooth LE scanners using Python 3.9
- Designing simple mobile apps to identify and record BLE pairing requests
- Programming Nordic based bluetooth speakers
- Setting up Unity Scenes real time connecting one BLE sensor
Through integrations with BLE, today's devices become smarter without intensive energy use, reduced cost, increased speed in configuration tasks, improved accuracy in data transfer, simplified interoperability between different vendor products and secure data encryption. With the help of specialized Freelancer expert BLE Developers, businesses can design robust integrations to realize their visions for the future of IoT. If you have an idea for a project that requires BLE integration – post it on Freelancer now and hire experienced BLE developer to turn it into reality!

Complete Prototype Development Project Thank you for reviewing my project. My goal is to develop a working proof-of-concept prototype for, a universal rechargeable television remote system with a TV-connected paging module that helps users locate misplaced remotes through sound and vibration alerts. I am interested in working with one engineer throughout the entire development process if we are a good fit. Project Budget: My target total development budget for this proof-of-concept project is $3,000 USD. I would like to complete the project using milestone-based payments as deliverables are completed and approved. Proposed Milestone Structure: Milestone 1 – $300 Due: June 15, 2026 • Technical feasibility review • Hardware recommendations • BLE/RF communication ...
I need a single code-base mobile app—built in Flutter or React Native—that pairs over Bluetooth Low Energy with a white-label smart band using the manufacturer’s BLE SDK. I will provide the SDK libraries, UUIDs, and documentation as soon as we kick off. The goal is to compile and ship the same code to both iOS and Android stores. Core scope • Implement a smooth pairing/re-pairing flow. • Pull real-time metrics (steps, heart rate, battery level, etc.) and display them in simple dashboards. • Store data locally for offline access and render basic charts. • Support OTA firmware updates exposed by the SDK. • Produce signed .ipa and .aab builds ready for App Store and Google Play submission, along with clean, well-commented source code.

We are looking for an elite, high-level mobile developer to build the Phase 1 MVP of PJ MONEY, a next-generation fintech ecosystem designed to transform financial inclusion. If you are an amateur or a beginner, do not apply. We only want visionaries who have already built complex, production-ready applications and who want to leave their mark on the technology world. This is a long-term contract. PJ MONEY is the first milestone of a global 4-Phase ecosystem including an Advanced Marketplace (Phase 2), Urban Logistics Grid with background wake-locks (Phase 3), and Micro-investments. Excellence in Phase 1 guarantees your retention for the entire multi-phase journey. Key Architecture Requirements for Phase 1 MVP: Low-latency backend using MQTT binary protocol over HTTP polling for 2G netwo...
