Bluetooth Low Energy (BLE) Jobs

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.

1. Develop an Android APP 2. Communicate with game devices via Bluetooth (BLE) 3. You can read and set device information on the app 4. You can set the device on the app, such as LED color, volume, game mode, etc 5. Upgrade the firmware issued by the device through the app 6. The hardware equipment is a system based on ESP32. The developer should have some basic knowledge about ESP32. 7. The app needs to be connected to specific game devices, and the developer should preferably be located in Beijing

Hi, I need firmware designers who have worked on ESP32-CAM module before. Kindly place bid if you can do firmware for that module. Firmware would include following tasks: 1. Image processing 2. Audio processing 3. Video storage and transfer via UART Further details will be shared with selected freelancers only. Thanks.

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.
