Covid Bracelet

** Contributions Welcome! **

Get Started

We use Zepyhr master as we need a newer mbed TLS as the ones that ships with Zephyr 2.2. We are waiting for the Zepyhr 2.3 release. To build, please install Zephyr and compile via west. Note that Platform.io sadly does not support Zephyr 2.3 rc / Zepyhr master at the current time.

Features

  • Code sends out and receives exposure beacons
    • Rolling, encrypted, anonymous beacons as specified by Google and Apple
    • Compatible with Apple iOS and Android phones
  • Upon infection upload keys to a public database
  • Retrieve keys of infections from database
    • to check for exposure
  • Based on Zephyr OS and NRF52 BLE SOCs

** Note: this is a proof of concept and not ready for production **

Open / Possible next steps

  • extensive compatibility testing with Apple iOS and Android devices
  • contininous integration testing
  • set device name in Flash
  • fix entropy: keys are always the same on boot up
  • set scanning interval to the correct value, for now we just use the default
  • set advertisement interval, correct value, for now we just use the default: should be 200-270 milliseconds
  • store long-term contacts in flash
  • Energy efficiency
  • BLE advertisements sets
  • Secure GAT services
  • More platforms / OS?
  • time sync
  • firmware of the air updates (signed)

##TODOs Wristband Possible platforms for real-world deployment many, as many of the cheap fitness trackers base on NRF52 or chips with similar capabilities. However, many would need the firmware to be shipped to manufactures.

  • Watch UI
  • Pine Time could be good for testing

##TODOs App / Basestation

  • extend this beyond the simple basestation
  • read keys form national databases
