Bluetooth Low Energy (BLE) Jobs

BLE is a version of Bluetooth that has a lower energy consumption when compared to classic Bluetooth. Lower costs while maintaining the same communication range make BLE a viable wireless personal area network for many products including mobile operating systems iOS, Android, Blackberry and Windows 10. BLE is primarily used for video games, security, healthcare and fitness, PCs and mobile phones.

    We are looking for a senior firmware developer who can consult us on various aspects of development for BLE application using the NRF52 and other Nordic Semiconductor System-on-Chips (SoCs). The first job on hand (this request) is low power optimization of an existing application, this would require good co-ordination with our developers (remote teams), firmware review, bug fixes, and adaptations to reach the desired power consumption levels. Expert knowledge of low-power schematic design, firmware development and integration is a must. We are looking for individuals and NOT companies (any time zone is okay, but we prefer Central Europe).

    We are looking for a Bluetooth and Wi-Fi spectrum scanning software. Based on the sigint concepts of Kali Linux. The "Detection" should gather the Mac Addresses and SSID's of wireless and wearable devices using various (pre-advised, and customized) software technologies. We prefer it being developed in C#, C or Java. The connectivity between the Detector and the Server makes use of NodeJS. The detection software eventually must run on a ARM-chip based Raspberry Pi Model 4, 2GB RAM. We have a fixed budget.

    I need to build a mobile app for indoor maping. The map should be shown as 3d. I prefer to use react native, but I'm not sure what is the best option for me. Also the app should guess the rough location by reading the distributed bluetooth beacons.
