bangle.js (smartwatch)

Unfortunately there are not many smartwatches focused in opensource apps, and less having GPS functions.

So if you want to use opensource in your watch during your activities you have to assume some limitations and wait or help for community improvements.

• Heat rate function, is really unreliable, and it seems a problem of the sensor hardware, so even if software can reject weird measures there is not much hope.
  
• GPS, seems reliable enough, and battery last long with it tracking
• Apps, there are couple of good apps that are receiving support, see below. 
• Support, besides other you can be part of the community and the solution.

 

bangle.js2 (smartwatch)

• GPS and a Heat rate sensor more acqurate than bangle.js1 one.
  

Bluetooth Heart Rate Monitor (bangle.js2)

 App id: bthrm

Overrides the usage of the internal HR sensor with an external Bluetooth  

Settings: 

1) Mode=Default - Replaces internal HRM with BT HRM and falls back to internal HRM if no valid measurements received. 

2) Search for sensor

3) Open app?

4) see values on widget (widhrm,...

Not compatible with "Heart Rate Monitor(hrm)"

Bluetooth Heart Rate Monitor (Lite)(bthrmlite)

 Old version, and lightweight without configuration and the recommended for Bangle.js1

BLE GATT HRM Service (bootgatthrm)

 A GATT HRM Service to advertise the measured HRM over BLE. Compatible with Opentracks and Fitotrack.  Detected but not working with Runnerup and AAT

 

GPS recorder (bangle.js, 2)

Opinion: It is a very reliable app+widget that can work in background, so you can use other functions during the activity, and when completed the track can be exported in a standard format to other apps.

The look and feel is very old school, just text without icons, and the menus can be managed only through buttons. 

Tips:

Using OpenStreetMap from web apploader you can upload a map/tiles and this map can be displayed in the background of the track.

As getting a valid GPS signal takes quite long, and you require it to start tracking, from web apploader use the app "Assisted GPS Update (AGPS)" to download satellite info for a day (8kB) or a week (46kB).

Missing functions: 

• Follow a track. I mean functions to import a track, display the track in screen and track a new one over it (in a different color)
• Use of touch screen, i.e change of screen by sliding movement  
• A Graphical dashboard, showing summary and enabling pause in friendly and quickly way.
  

Import/export:

internal file format:

timestamp,latitude,longitude,altitude    (but more attributes can be added to be logged , such as  HR, HR(bluetooth) ,HR int or steps.

Export format: (from apps loader page): .KML , .GPX 

Tip: exporting from Android's Chrome, then the downloaded track file can be open with some apps.

 

RUN (bangle.js)  RUN+

Opinion: the user interface is based in a single screen managed only by buttons, and it can track your activity including lot of precision and heart rate

But the worst (hopefully it will be corrected soon)is that the apps is not available as widget so can't work on background and the tracking has too much precision (and not necessary) so the output file grows too much.

As curiosity this app is not written in basic Javascript but TypeScript that after "compiled" generates a obfuscated Javascript, for developers maybe it is not important but for other can be an additional step.

Missing functions: 

• Run in background 
• A parameter to define the time between tracking points
  
• Display a track or statistics
• Use of touch screen, i.e change of screen by sliding movement 

Import/export:

internal file format:

timestamp,latitude,longitude,altitude,duration,distance,heartrate,steps
1602954919045,38.418089,-0.x09480,36.88,0,0.65,104,1

 Export format (from apps loader page): .KML , .GPX 

 

Route viewer (bangle.js)

Opinion: it allows to display map  and/or a track in the screen and your current GPS position over it. Also it shows distance an a direction arrow.

 Is not a standard Javascript app, but a realtime generated app+map track. From the apps loader web you load a .KML and the result is uploaded as bangle.js app

Missing functions:

• zoom function is missing 
• a single a app able to open different tracks/maps
• 
  Direct access to track files in memory from banglerun or GPSrecorder
  

Import/export: import .KML

Fitotrack (android, FOSS)

Opinion: A good app for sports and well supported, has voice notifications to inform about pace, etc...

Supports external heart rate sensor(fails with decathlon BLE and not paired devices?) and can display sections/intervals, elevation/speed graphs

Missing functions: 

• Text notifications that other apps can process and send to smartbands/watches 

Import/export:

Export:  GPX

 

Opentracks (android, FOSS) 

"+OSM Dashboard por Opentracks"

Opinion: a  good tracking app with a easy an intuitive and complete dashboard.

To be able display the activity in a map it requires to install "OSM Dashboard por Opentracks" (another small opensource app) and from opentracks "show on map" and select "OpenTracks Dashboard API", and button "Always".

Advanced functions, as voice notifications, Interoperability with BLE devices: Heart rate (chest strap or watch), cadence, power, speed, and wheel size

It shows intervals, elevation/speed graphs and has voice

The Dashboard with the default layout shows many information fields, and can be customized.

Missing/Concerns:

-Permission: "Location always", is not being used, so it can stop tracking with saving mode or lossing the foreground

Import/export:

Export:  GPX, KML,KMZ, KMZ(inc photos)

@fdroid

OSMand (android, FOSS)

Opinion: though focused in navigation, it has tracking function and many options and features, such as following a previous track.

Require more learning and adaptation than other tracking apps, but the potential is incredible.  

Import/export: .GPX

@fdroid

 

Runnerup (android, FOSS)

 

Functions: Workouts and intervals, audio notifications, Laps, Map(using version from Play), sensors (ANT+, BLE), upload activity to some social networks

There are versions that can run in old in Android4(usually lighter and smaller)

Missing functions: 

• Display the map during the exercise tracking.
• Text notifications that other apps can process and send to smartbands/watches 

  Import/export: 

Export to: database, .GPX .TCX

Import: only from database

@fdroid

AAT (android)

An activity tracker, with a good UI but that can require more time to get used, for example the dashboard is called "Cockpit"

Activity: preconfiguration (autopause, recording filter, backlight,..)

cockpitA: fullscreen stats (HR in a smaller font size),map, graph

cockpitB: splited screen stats/map,  stats are in a smaller font size)

Advanced functions, through touch on topleft/bottom (cockpitB screen) or bottom(cockpitA map screen)

Support/Functions:  online Maps(several ones)/offline maps, BLE sensors,...

Import/export: .GPX

@fdroid

Missing functions: 

• HR limits and warning notifications
  

Strava(android/web - commercial)

It is not opensource but if you want share your activities with friends probably they use it.

Fortunately you can use other apps during the activity and just upload to share with others.

Import/export:

Import/Export: .TCX, .FIT or .GPX

Import from  http://www.strava.com/upload/select

Wikiloc (android/web - commercial)

An app/web especially useful to find and share tracks for different sports (like mountain paths), sometimes well described, classified and with pictures

The app can be used to track or follow a previously downloaded track, supports offline maps and has basic statistics for the activity.

Negative points, besides being commercial it has some dependencies on Google services, that is specially bad for devices without Play services (such as BlackBerry10  android runtime)

Import/export: app exports to .GPX

OruxMaps (android/web - commercial)

Powerful GPS app with plenty of functions, requires time to learn and get the best of it. Supports loading a track and tracking/following over it.

Import/export:  import .KML and .GPX

Export to   .GPX, .KML, .KMZ, .FIT, TCX, .CSV

Upload to: Strava and other services ...

Avoid BLE issues

Error reading the file

when using NrfToolbox you can select the app to pick the file (a file manager)

ES explorer has 2 modes, so if one fails the other can work.

"DFU File ...not found"

turn off other bluetooth devices (specially if they were pair before)

use a different phone that you have never pair

companion apps like d6notification or gadgetbridge can try to connect even if they seem closed

Error GATT ERROR  a

       keep trying,

       disable/enable phone's Bluetooth

       kill daflasher app

       uninstall BLE apps (d6notification)
       turn off phone or
       try "nRF Connect" app as an alternative to Daflasher, as it also can flash a DFU

flashing espruino+ninebot/eucWatch to a P8 smartwatch

Flashing espruino+eucWatch (formerly ninebot-one)

[updated]

Intro: 

Espruino: is javascript engine ported to nrf52 and P8 (fanoush)

Ninebot-one (nb): is a watch software that besides time, has some additional functions, especially the one that originally gave name to the software, a "page" that displays info from a unicycle mobility device.

eucWatch: latest version and new name for the Ninebot-one software

ATCwatch: another software for P8 based in Arduino (see other articles of this blog)

Steps:

1) Flash bootloader

1.1) if you have Dafit/stock ROM

or 

1.2B) if you have ATCwatch installed on the P8  

2) Daflasher step

3) Espruino step (PC and Chrome)

Configuring/coding nb espruino:

Using nb/ninebot UI

  

From a browser download following apps from github

• DaFitBootloader23Hacked.bin (A custom Bootloader using the preInstalled SoftDevice5.0.1)

• FitbootloaderDFU2 zip    (Soft Device 2)
• espruino_2v0x.xxx_p8_SDK11_SD20.zip  (from fanoush github page for p8)
  

If you start from p8 default status/Dafit stock then you have to install before the first 2 files.

 1) Flash bootloader

1.1) if you have Dafit/stock ROM 

 You must install before:

    DaFitBootloader23Hacked.bin

    FitbootloaderDFU2 zip 

(common steps with flashing ATCwatch)

 

On Daflasher

Select: P8 

(wait until button "Select File" is enabled)

Select File : DaFitBootloader23Hacked.bin

P8 screen [green screen, progress bar and end in 3 color squares]

Select: ATCdfu
Click button "Do DFU Update"
Selectfile: FitbootloaderDFU2 zip [check Use Nordic Bootloader]

(it can take a long time, fail several times during the process and recontinue from last %. But at the end it should complete flashing the file, speed is slow i.e 2,20kB/s)

  P8 screen    [red square and ATCnetz.de]

 

1.2) if you have ATCwatch installed on the P8

From p8 menu, Click "Bootloader"

  P8 screen    [red square and ATCnetz.de]

 

2) Daflasher step

At BLE devices list

Select: ATCdfu

Click button "Do DFU Update"
   [Checked box: Nordic bootloader]
   [Unchecked box: Toggle Bluetooth]
Select DFU file:  espruino_2v0x.xx_p8_SDK11_SD20.zip  

3) Espruino step (PC and Chrome)

(only tested on Windows) 

    Bluetooth has to be on

•     from Chrome (tested in v84):  https://www.espruino.com/ide/#

   "Connection Icon", "Web Bluetooth", P8 xxxx

   on left side terminal type:

             "require("Storage").eraseAll()"

 

•  how to Flash /Upload "init" file   
  
  

Having  right side windows clear (empty of code)

Drag an drop "init" file to left side (

Click on Send to espruino arrow down icon, choose Upload destination, "Storage" , choose name ".bootrst"

 Click on ".bootrst"

 

•   (optional) Edit "handler" file before upload 
  

Depending on P8 model, touch and accelerator controller can change

 

for example for a P8a/TFK5 set

      const touchtype="716" and acctype="BMA421"

 whereas a P8b can be a touchtype="716" or "816S" and acctype="SC7A20"

• Upload files
  

[enter in DEV mode]

  type on the left side:     reset() ,   [press enter while holding the button on the p8]

 

>reset()

=undefined
Welcome!
*** DevMode ***
Short press the side button
to restart in WorkingMode

•    Click on Storage/HD icon (Access files in device's storage),   "Upload a file":  handler, main, settings, calc,...

  (handler, main, settings, minimum files required for basic/testing)

  (euc file is not required, only for ninebot unicycle owners).

• Verify/execute
  

Click on Storage/HD icon (Access files in device's storage), verify existence of files and .bootrst

short tap on the button, and it will boot to working mode

 On left side terminal, execute command "reset()" or "E.reboot()"  (last one reset the hardware and loose the time)

DEV mode: (required for future files upload)

Do a reset() while holding the p8 button

from Settings-info- long press in restart button

 

Configuring/coding nb espruino:

During file upload, time is set on espruino. However, depending on timezone  value for an attribute, the displayed time can be wrong.

 

file: init/.bootrst  (Now .bootcde)

E.setTimeZone(2);

// 3=default

// Spain 1 winter time  2 summer time 

 

file:handler

const touchtype="716"; //716 for P8a/TFK | 816|816s for P8b

 

(for models and hardware check a previous post)

flashing/restore the original P8 - stock dafit 

Intro:

Note that going back to Stock-Dafit disables the possibility of later OTA/BLE flashing. So no more easy way to flash experimental OS/ROM. You can still do it but it will require to open the back lid and connect a cable to pins)

You need to download  

• SoftDevice: ATCdfuFromSD2toSD5.zip  (from atc1441 github page) 
• The stock "firmware" application, you can try get the package from dafit upgrade function, and it will be .bin file of 1xxKB
•  

Generate DFU package/nrfutil

Then you need to create DFU package containing the bin with nrfutil, a private key will be applied to the package. Though the previously downloaded SD5 will accept any possible key.

>nrfutil version  (nrfutil version 6.1.0 )

>nrfutil keys generate myprivate.key

Common problems and solutions

• Device is not found in BLE list

        turn off other BLE devices around
        stop or remove other apps that are using BLE connections

• Progress percentage stop a some point, or it is is increasing in each attempt

      Do not panic and keep trying because to complete the flashing it can require several attempts, including restarting the P8 with a shortcut.

• Error GATT ERROR  until success

       keep trying,

       disable/enable phone's Bluetooth

       kill daflasher app

       uninstall BLE apps (d6notification)
       turn off phone or
       try "nRF Connect" app as an alternative to Daflasher, as it also can flash a DFU 

• Daflasher DFU FILE NOT FOUND
• try with different file explorers
• ES explorer (has 2 pick file 2modes), CXexplorer and Amaze
  
• Reset the watch. requires to open the back lid, and create a Short in the battery, (during decs of a second) connect with metal both pins (+ and -)

Software/Images

Most of raspberry images are based in copy files to SD formated in FAT, and during the 1st boot, original partition is dynamically resized  and new partitions are created.


rpix86 is a PC emulator for the Raspberry Pi

Tools:Windows Software
Ms. Windows is not the best environment to work with disks, filesystems etc.. but using the following apps we can do most of the tasks without the need of rebooting a Windows computer.

Win32DiskImager.exe (GPL)
Linux Reader (Diskinternals)
EaseUS Partition Master (EaseUS)

There are better software for Windows\DOS and Linux but at least the previous are gratis



Installation

//Raspbian//

dd

gparted

wifi config


multimedia player GUI for omx player
>>>from https://github.com/KenT2/tboplayer
tboplayer
A GUI interface using jbaiter's pyomxplayer wrapper to control omxplayer

Required pexpect:
wget http://pexpect.sourceforge.net/pexpect-2.3.tar.gz
     tar xzf pexpect-2.3.tar.gz
     cd pexpect-2.3
     sudo python ./setup.py install

Installing tboplayer:
From a terminal window open in your home directory type:
     wget https://github.com/KenT2/tboplayer/tarball/master -O - | tar xz

There should now be a directory 'KenT2-tboplayer-xxxx' in your home directory. Rename the directory to tboplayer

Open the tboplayer directory and from a terminal opened in THIS directory:

    python tboplayer.py

TBOPlayer is developed on Raspbian Wheezy with python 2.7

1. Uncompress downloaded file
2. Identify SD card device (i.e /dev/mmblkxx) (1)
3. Format/remove partition from SD card. Disks or Fdisk (2)
4. Applying image to SD
•  sudo dd if=/path/sd.img of=/dev/mmcblk0 (3)
•  /path/ mounter folder where image is placed
5. Boot Raspberry with SD
• (Raspbmc will do some actions over SD, Sucha as partition resizing etc)
6. (optional) From PC, resize/create partitions
• (i.e with gparted) (4)
• Create a fat32 partition
• Copy multimedia to SD

(1) use Disks, dmesg, ...
(2) if there is problem try with a different card reader, usb to SD adaptor,..
(3) Use dd command or restore image from Disks on GUI, wait because it can take sometime and there is not a progress bar
(4) gparted recommended, but other software could done this action

Acronyms of Maps
TTS, Text to Speech, detailed driving instructions are provided using computer voices. The instructions include distances, road-names, directions to major cities, etc.
ALG is Advanced Lane Guidance. This comes in two parts. Part one are lane-use instructions for large intersections on screen, at the same location that is used for turn-left/right instructions. Part two are splash screens with a sort of very simple windscreen view.
ASR is Assisted Speech Recognition, where you can enter an address by talking to your TT.
C-speech are the files in the map needed for ASR.
Voice Control: TT control with one tap on the screen and your voice commands. (Requires a working TTS voice)
IQ routes is a planning system using real average speeds instead of maximum speed on a road. For this the map contains tables with the average speeds for the 24 hours/day, 7 days/week.
