SimpleWeather service : new weather implementation
This new implementation of the weather feature provides a new BLE API and a new weather service. The API uses a single characteristic that allows companion apps to write the weather conditions (current and forecast for the next 5 days). The SimpleWeather service exposes those data as std::optional fields. This new implementation replaces the previous WeahterService. The API is documented in docs/SimpleWeatherService.md.

|

* How to upload events to the timeline?
|
||||
*
|
||||
* All timeline write payloads are simply CBOR-encoded payloads of the structs described below.
|
||||
*
|
||||
* All payloads have a mandatory header part and the dynamic part that
|
||||
* depends on the event type specified in the header. If you don't,
|
||||
* you'll get an error returned. Data is relatively well-validated,
|
||||
* so keep in the bounds of the data types given.
|
||||
*
|
||||
* Write all struct members (CamelCase keys) into a single finite-sized map, and write it to the characteristic.
|
||||
* Mind the MTU.
|
||||
*
|
||||
* How to debug?
|
||||
*
|
||||
* There's a Screen that you can compile into your firmware that shows currently valid events.
|
||||
* You can adapt that to display something else. That part right now is very much work in progress
|
||||
* because the exact requirements are not yet known.
|
||||
*
|
||||
*
