In early December, the Bluetooth SIG association published the first draft of the new specification Portable exhibition notification service, in our language the notifications of exposure to COVID-19 in portable devices.
This means that we will soon be able to track COVID-19 exposure directly from our bracelet or smart watch and not just via mobile, and Google has started to implement this support in Android
Exposure notifications on wearable devices
Google Play Services version 20.50.14 hide references to the new exposure tracking in their source code via other Bluetooth devices.
Text strings refer to the synchronization of our mobile with a compatible mobile and that the the phone will use this device to securely collect and share random IDs with other devices nearby
This means that with COVID-19 exposure notifications turned on, we can leave the cellphone at home or at the box office at work or at the gym and continue to perform a follow-up of the exhibition with our bracelet or watch. By synchronizing the laptop with the mobile, it can alert us if we have been exposed. So if we don’t take the mobile with us, we won’t stop following our exposure.
Wear OS and other devices are expected to support new exposure notifications in the coming months. More than 130 partner companies of the Bluetooth association are working to make them available as soon as possible.
