• Tempo-BT is the Bluetooth LE-capable version of the Tempo skydiving logger device. • It is based on the u-blox NORA-B106 (Nordic Semiconductor nRF5340). • Sensors and Capabilities GPS/GNSS position tracking using a u-blox SAM-M10Q 6-DOF Inertial measurement / gyro pose tracking using a TDK InvenSense ICM-42688-V Barometric pressure / temperature logging using a Bosch BPM390 3-DOF Compass/Magnetic measurement using a Memsic MMC5983MA (not utilized in the current version of the project) See more on GitHub .

Article Summaries:

  • A new Bluetooth Low Energy (BLE) variant of the Tempo skydiving logger, called Tempo‑BT, has been released. Built around the u‑blox NORA‑B106 (Nordic nRF5340) microcontroller, the device adds wireless connectivity to the existing hardware. It incorporates a u‑blox SAM‑M10Q for GPS/GNSS position tracking, a TDK InvenSense ICM‑42688‑V 6‑DOF inertial measurement unit for pose tracking, a Bosch BPM390 for barometric pressure and temperature logging, and a Memsic MMC5983MA 3‑DOF compass (currently unused). The project’s source code and documentation are available on GitHub.
