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!

    APP AND PCB HARDWARE DESIGN Both to be delivered by the same developer. I'm seeking a proficient electronics engineer and app developer to create a PCB, software, and implement an app for a Bluetooth locator, like a simple key finder. There are many products like this already on the market at very low prices. PCB must be small, alarm very loud and power consumption low. Bluetooth should automatically connect to the phone. PCB should power on when movement is detected and remain on for a period of time, set within the app. A tilt/vibration sensor detects when the PCB moves and turns on the power. Key features of the Bluetooth device must include: - Alarm sound feature - press button on phone to sound a loud alarm on PCB - Flashing light feature - light flashes when alarm sounds - S...
