Alpine Navigator
================
App that performs GPS monitoring to track and display position relative to a given origin in realtime.
![screenshot](./sample.png)
Functions
---------
Note if you've not used GPS yet I suggest using one of the GPS apps to get your first fix and confirm as I've found that helps initially.
The GPS and magnetometer will be turned on and after a few moments, when the watch buzzes and the dot turns from red to pink, that means the GPS is fixed. all your movements now will be displayed with a line drawn back to show your position relative to the start. New waypoints will be added based on checking every 10 seconds for at least 5 meters of movement. The map will scale to your distance travelled so the route will always remain within the window, the accelerometer/pedometer is not used - this is a purely GPS and compass solution so can be used for driving/cycling etc. A log file will be recorded that tracks upto 1000 waypoints, this isn't a big file and you could remove the limit but I've kept it fairly conservative here as it's not intended as a main feature, there's already good GPS recorders for the Bangle. The following other items are displayed:
1. altitude at origin, this is displayed left of the centre.
2. current altitude, displayed centre right
3. distance from origin, bottom left (meters)
4. distance travelled, bottom right (meters)
5. compass heading, at the top
For the display, the route is kept at a set resolution, so there's no risk of running into memory problems if you run this for long periods or any length of time because the waypoints will be reduced when it reaches a set threshold so you may see the path smooth out slightly at intervals.
If you get strange values or dashes for the compass, it just needs calibration so you need to move the watch around briefly for this each time, ideally 360 degrees around itself, which involves taking the watch off. If you don't want to do that you can also just wave your hand around for a few seconds like you're at a rave or Dr Strange making a Sling Ring but often just moving your wrist a bit is enough.
The buttons do the following:
BTN1: this will display an 'X' in the bottom of the screen and lock all the buttons, this is to prevent you accidentally pressing either of the below. Remember to press this again to unlock it! soft and hard reset will both still work.
BTN2: this removes all waypoints aside from the origin and your current location; sometimes during smaller journeys and walks, the GPS can give sporadic differences in locations because of the error margins of GPS and this can add noise to your route.
BTN3: this will pause the GPS and magnetometer, useful for saving power for situations where you don't necessarily need to track parts of your route e.g. you're going indoors/shelter for some time. You'll know it's paused because the compass won't update it's reading and all the metrics will be blacked out on the screen.
Things to do next
-----------------
There's a GPS widget that's been developed to leverage low-power mode capability on the sensor, will look to incorporate that.

# GPS Service
A configurable, low power GPS widget that runs in the background.
## Goals
To develop a low power GPS widget that runs in the background and to
facilitate an OS grid reference display in a watch face.
* An app that turns on the GPS and constantly displays the screen
will use around 75mA, the battery will last between 3-4 hours.
* Using the GPS in a Widget in Super-E Power Saving Mode (PSM) with
the screen off most of the time, will consume around 35mA and you
might get 10hrs before a recharge.
* Using the GPS in Power Saving Mode On/Off (PSMOO) with suitable
settings can reduce the average consumption to around 15mA. A
simple test using a 120s update period, 6s search period was still
running with 45% battery 20 hours after it started.
## Settings
The Settings App enables you set the following options for the GPS
Service. Go to Settings, select App/Widgets and then 'GPS Service'.
- GPS - On/Off. When this value is changed the GPS Service will be
powered on or off and the GPS Widget will be displayed.
- Power Mode:
- SuperE - the factory default setup for the GPS. The recommended
power saving mode.
- PSMOO - On/Off power saving mode. Configured by interval and
search time. Choose this mode if you are happy to get a GPS
position update less often (say every 1 or 2 minutes). The longer
the interval the more time the GPS will spend sleeping in low
power mode (7mA) between obtaining fixes (35mA). For walking in
open country an update once every 60 seconds is adequate to put
you within a 6 digit grid refernce sqaure.
- update - the time between two position fix attempts.
- search - the time between two acquisition attempts if the receiver
is unable to get a position fix.
## Screenshots
### GPS Watch face
* The Age value is the number of seconds since the last position fix was received.
![](gps_face.jpg)
### Grid Reference Watch face
* The time shown is the timestamp of the last position fix.
* The age value is shown at the bottom of the screen.
![](osref_face.jpg)
## Interface for Apps
The code below demonstrates how you can setup and start the gpsservice from your own App.
```js
function test_gps_on() {
var settings = WIDGETS.gpsservice.gps_get_settings();
// change the settings to what you require
settings.gpsservice = true;
settings.update = 65;
settings.search = 5;
settings.power_mode = "PSMOO";
WIDGETS.gpsservice.gps_set_settings(settings);
WIDGETS.gpsservice.reload(); // will power on
}
```
In your app can retrieve the last fix as and when required.
```js
var fix = {
fix: 0,
alt: 0,
lat: 0,
lon: 0,
speed: 0,
time: 0,
satellites: 0
};
// only attempt to get gps fix if gpsservice is loaded
if (WIDGETS.gpsservice !== undefined) {
fix = WIDGETS.gpsservice.gps_get_fix();
gps_on = WIDGETS.gpsservice.gps_get_status();
}
if (fix.fix) {
var time = formatTime(fix.time);
var age = timeSince(time);
```
When done you can turn the gpsservice off using the code below.
```js
function test_gps_off() {
var settings = WIDGETS.gpsservice.gps_get_settings();
settings.gpsservice = false;
settings.power_mode = "SuperE";
WIDGETS.gpsservice.gps_set_settings(settings);
WIDGETS.gpsservice.reload(); // will power off
}
```
## To Do List
* add a logging option with options for interval between log points
* add graphics and icons to the watch faces to make them look nicer

# Intervals app
Just my first app to test this amazing smartwatch.
The idea is to create a simple app which allows to define a workout, being able to configure the work time, rest time and number of sets. Try it out, it is quite simple.
This is obviously version 0.01 but it should work.

# Morphing Clock Plus
Based on Morphing Clock with more readable seconds and date, and an additional simple stopwatch.
![](Screenshot.JPG)
## Usage
In addition to the Morphing Clock, a simple stopwatch can be started in the lower part of the display.
BTN3 starts and stops the stopwatch.
BTN1 resets/clears the stopwatch.
## Requests
Please leave bug reports and requests by raising an issue [here](https://github.com/skauertz/BangleApps).
## Creator
Sebastian Kauertz https://github.com/skauertz
