* permanent storage on flash of last keys, beacons and exposures (storage is limited, see [storage math](#some-storage-math) for details)
* parsing of Exposure Key export binaries as defined in [Exposure Key export file format and verification](https://developers.google.com/android/exposure-notifications/exposure-key-file-format) (big thanks to [nanopb](https://github.com/nanopb/nanopb) for making this easier than I thought!)

* delete data
* set language
* enter tan for infection status (dummy for now)
* battery support with ESP32 dev-boards with integrated LiPo support
### Features in development
* automatically receive Exposure Key export from web (started with [Corona Warn App](https://github.com/corona-warn-app))
* send infected status (will test [Corona Warn App](https://github.com/corona-warn-app))
* battery support
* 3d print case
### Limitations/Problems/Questions
* WiFi or other external connection needed for infections status (auto-connect to open WiFis?)
* obtaining accessibility
* all parameters (scanning time, thresholds etc.)
* memory (RAM) is really low with BLE and WiFi enabled, unzipping a Exposure Key export not possible for now, maybe disable BLE service for download.
* service UUID is send reversed, RPI and AEM also send in reverse? Don't know BLE specification enough

### ena-eke-proxy
Module to decode Exposure Key export.
This module is for connecting to an Exposue Key export proxy server. The server must provide daily (and could hourly) fetch of daily keys in binary blob batches with the following format
