Andreas Shimokawa 7e1700250f Pebble: add dev option to force latest notification protocol usage
When enabled it forces to use 3.x notifications on FW 3.x (2.x notifcations on FW 2.x)
When disabled 2.x notification on FW 2.x and 1.x notifications on FW 2.x are used (which is recommended)

This allows Pebble Time users to do further tests.

cpfeiffer e562fa9870 Light sleep and deep sleep was mixed up. Corrected graphs again. #45
Use dashed limit lines, still not perfect.
2015-06-19 01:14:58 +02:00
cpfeiffer f9e5ab5fc1 Some more refinements to sleep display (#45):
- display the recorded level of deep sleep rather than a constant
  (I hope this works for morpheuz, too!?)
- give light sleep a minimum value, because it's sometimes 0 for Mi Band
2015-06-19 00:20:38 +02:00
cpfeiffer 03fa05756e As a test, draw limit lines for sleep/activity changes.
Unfortunately it looks like the labels for it don't get rendered ;-(

cpfeiffer 83079b0456 Stub for device notification changes 2015-06-18 23:07:22 +02:00
Daniele Gobbetti cb3be26349 Do something when we receive a CharacteristicChanged message
on the UUID_CHARACTERISTIC_BATTERY characteristic.

This is a first try at addressing #71

Please note that this will probably not work at this point, but it's
worth a try. To make it work probably we have to tell the device to
send updates, and we don't know how to do it.

Andreas Shimokawa bffd7f332f remove SleepChartActivityOld, as the new one is usable now ;) 2015-06-17 08:18:24 +02:00
cpfeiffer a5ae7acc63 Improved sleep chart #45
- use just one data set, because multiple data sets is not supported
  by MPAndroidChart (the way we need it)

Now there is hardly any space between the bars anymore

Also:
- allow scaling x and y axis independently via pinch gesture
- set fixed y max value (1.0) so that the display is stable and
  independent of the actual available data
- (at least temporarily) display y labels
2015-06-17 07:03:50 +02:00
cpfeiffer 8709b95a95 Use a single data set instead of one per activity kind
The reason is that multiple data sets will always be grouped.
If we add null values to fix the grouping issue, we will still have
space between the bars.

Daniele Gobbetti 8b268a676c Refactoring of the data ingestion method.
* no more ByteBuffer, but a fixed size byte array that gets flushed everytime it's needed
* log of activity data to a separate file (no DB integration yet)
* the size of the buffer must be a multiple of 3 (1 minute of data = 3 bytes) and 20 (the normal size of the chunks we get from the device)
* better logging and more comments in code
