# GPS Setup
An App and module to enable the GPS to be configured into low power mode.
## Goals
To develop an app that configures the GPS to run with the lowest
possible power consumption.
Example power consumption of the GPS while powered on:
* 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 with 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 App
The Settings App enables you set the options below. Either start the
App from the launcher or go to Settings, select App/Widgets and then
'GPS Setup'.
When you exit the setup app, the settings will be stored in the
gpssetup.settings.json file, the GPS will be switched on and the
necessary commands sent to the GPS to configure it. The GPS is then
powered off. The GPS configuration is stored in the GPS non-volatile
memory so that next time the GPS is powered, that configuration is
used. These settings will remain for all apps that use the GPS.
- Power Mode:
- **SuperE** - the factory default setup for the GPS. The recommended
power saving mode. If you need frequent (every second) updates on
position, then this is the mode for you.
- **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.
## Module
A module is provided that'll allow you to set GPS configuration from your own
app. To use it:
```
// This will set up the GPS to current saved defaults. It's not normally
// needed unless the watch's battery has run down
require("gpssetup").setPowerMode();
// This sets up the PSMOO mode. update/search are optional in seconds
require("gpssetup").setPowerMode({
power_mode:"PSMOO",
update:optional (default 120),
search:optional (default 5)})
// This sets up SuperE
require("gpssetup").setPowerMode({power_mode:"SuperE"})
```
`setPowerMode` returns a promise, which is completed when the GPS is set up.
So you can for instance do the following to turn the GPS off once it
has been configured:
```
require("gpssetup").setPowerMode().then(function() {
Bangle.setGPSPower(0);
});
```
**Note:** It's not guaranteed that the user will have installed the `gpssetup`
app/module. It might be worth checking for its existence by surrounding the
`require` call with `try...catch` block.
```
var gpssetup;
try {
gpssetup = require("gpssetup")
} catch(e) {
E.showMessage("gpssetup\nnot installed");
}
```

/*
* GPS Setup app, hughbarney AT googlemail DOT com
* With thanks to Gordon Williams for support and advice
*
* UBLOX power modes:
* SuperE - will provide updates every second and consume 35mA, 75mA with LCD on
* PSMOO - will sleep for update time and consume around 7mA during that period
* after acquiring satelite fixes the GPS will settle into a cycle of
* obtaining fix, sleeping for update seconds, wake up, get fix and sleep.

Displays the GPS speed and altitude. One is displayed on the watch face using the largest possible characters depending on the number of digits. The other is in a smaller characters below that. Both are always visible. You can display the current or maximum observed speed/altitude values. Current time is always displayed.
# GPS Speed, Altimeter and Distance to Waypoint
Display Tap : Swaps the displays. You can have either speed or altitude on the large primary display.
You can switch between two display modes. One showing speed and altitude (A) and one showing speed and distance to waypoint (D).
BTN1 : Short press < 2 secs toggles the displays between showing the current speed/alt values or the maximum values recorded.
Within each display mode one figure is displayed on the watch face using the largest possible characters depending on the number of digits. The other is in a smaller characters below that. Both are always visible. You can display the current or maximum observed speed/altitude values. Current time is always displayed.
The waypoints list is the same as that used with the [GPS Navigation](https://banglejs.com/apps/#gps%20navigation) app so the same set of waypoints can be used across both apps. Refer to that app for waypoint file information.
## Buttons and Controls
BTN3 : Swaps the modes between Speed+[A]ltitude or Speed+[D]istance.
### [A]ltitude mode
BTN1 : Short press < 2 secs toggles the displays between showing the current speed/alt values or the maximum speed/alt values recorded.
BTN1 : Long press > 2 secs resets the recorded maximum values.
App Settings : Select the desired display units. Speed can be as per the default locale, kph, knots, mph or m/s. Altitude can be feet or metres. Select one of three colour schemes. Colours, high contrast (all white on black) or night ( all red on black ). Vibration can be used to indicate when a fix is lost or gained. One buzz for a lost fix and a double buzz when a fix is found.
### [D]istance mode
![](screen1.png)
![](screen2.png)
![](screen3.png)
![](screen4.png)
BTN1 : Select next waypoint. Last fix distance from selected waypoint is displayed.
### Both modes
BTN2 : Disables/Restores power saving timeout. Locks the screen on to enable reading for longer periods but uses maximum battery drain. Red LED (dot) at top of screen when screen is locked on. Press again to restore power saving timeouts.
BTN3 : Long press exit and return to watch.
BTN4 : Left Display Tap : Swaps which figure is in the large display. You can have either speed or [A]ltitude/[D]istance on the large primary display.
## App Settings
Select the desired display units. Speed can be as per the default locale, kph, knots, mph or m/s. Distance can be km, miles or nautical miles. Altitude can be feet or metres. Select one of three colour schemes. Default (three colours), high contrast (all white on black) or night ( all red on black ).
## Loss of fix
When the GPS obtains a fix the number of satellites is displayed as 'Sats:nn'. When unable to obtain a fix then the last known fix is used and the age of that fix in seconds is displayed as 'Age:nn'. Seeing 'Sats' or 'Age' indicates whether the GPS has a current fix or not.

## Power Saving
The The GPS Adv Sport app obeys the watch screen off timeouts as a power saving measure. Restore the screen as per any of the colck/watch apps. Use BTN2 to lock the screen on but doing this will use more battery.
This app will work quite happily on its own but will use the [GPS Setup App](https://banglejs.com/apps/#gps%20setup) if it is installed. You may choose to use the GPS Setup App to gain significantly longer battery life while the GPS is on. Please read the Low Power GPS Setup App Readme to understand what this does.
When using the GPS Setup App this app switches the GPS to SuperE (default) mode while the display is lit and showing fix information. This ensures that that fixes are updated every second or so. 10 seconds after the display is blanked by the watch this app will switch the GPS to PSMOO mode and will only attempt to get a fix every two minutes. This improves power saving while the display is off and the delay gives an opportunity to restore the display before the GPS power mode is switched.
The MAX values continue to be collected with the display off so may appear a little odd after the intermittent fixes of the low power mode.
## Waypoints
Waypoints are used in [D]istance mode. Create a file waypoints.json and write to storage on the Bangle.js using the IDE. The first 6 characters of the name are displayed in Speed+[D]istance mode.
The [GPS Navigation](https://banglejs.com/apps/#gps%20navigation) app in the App Loader has a really nice waypoints file editor. (Must be connected to your Bangle.JS and then click on the Download icon.)

# Walkers Clock
A larg font watch, displays steps, can switch GPS on/off, displays grid reference
The watch works well with GPSsetup, the Activepedom or Widpedom
wdigets. A tiny GPS power widget is waiting in the wings for when
the v2.09 firware is released.
## Features
- Displays the time in large font
- Uses BTN1 to select modeline display (eg battery status or switch between setting when in a function mode
- Uses BTN3 to select the function mode (eg turn on/off GPS, or change GPS display)
- two function menus at present
GPS Power = On/Off
GPS Display = Grid | Speed Alt
when the modeline in CYAN use button BTN1 to switch between options
- Display the current steps if one of the steps widgets is installed
- Ensures that BTN2 requires a 1.5 second press in order to switch to the launcher
this is so you dont accidently switch out of the GPS/watch display with you coat sleeve
- Displays the timestamp of the last GPS fix when the GPS is on
- Buzzes when the GPS aquires a positional satellite fix
- Displays the current OS map grid reference in a large font
- Displays the age of the current GPS position fix in seconds
- Works in tandem with the GPS setup app so that you can reduce the power consumption of the GPS
## BTN1 cycles the information line
- By default the modeline is switched off
- Click BTN1 once and display your steps (if one of the step widgets is installed)
- Click BTN1 again and it will show battery % charge
- Click BTN1 again and it will switch the modeline off
## BTN2 Long press to start the launcher
BTN2 is confiured to respond to a 1.5 second press in order to switch
to the launcher App. Simply press and hold until you hear a buzz and
release. This avoids accidently switching out of the watch app when
clothing catches it.
## BTN3 cycles the function mode
- Click BTN3 once and the GPS ON / OFF menu is displayed
- If the GPS is OFF then pressing BTN1 will turn it ON
- If the GPS is ON then Clicking BTN1 will turn it OFF
When the GPS is ON a second function menu can be displayed by
pressing BTN3 again. This will show options to change the GPS display
on the second line of the watch.
- Grid - will display the GPS position converted to an OS Grid Ref
- Speed - will display the GPS speed inforation supplied in the last GPS fix
- Alt - will display the altitude information

## Future Enhancements
* Ability to turn on the Heart Rate monitor
* Maybe a simple stopwatch capability
* Fix the screen flicker

# GPS Power Status Widget
A simple widget that shows the on/off status of the GPS.
The GPS can quickly run the battery down if it is on all the time so
it is useful to know if it has been switched on or not.
- Uses Bangle.isGPSOn(), requires firmware v2.08.167 or later
- Shows in grey when the GPS is off
- Shows in amber when the GPS is on
