Smart watches and wearable applications

Pebble

Was acquired by Fitbit. My Pebble repo was moved here, for archiving purpose.

Samsung Frontier

To get started

• Install the Tizen IDE.
  • Also install, through the Package Manager:
    • Wearable Emulator
    • Web app. development (IDE)
    • Extension SDK Samsung Certificate Extension
    • Extension SDK Samsung Wearable Extension
• To connect a remote device (like a Frontier watch), on the device:

> Settings > Connections > WiFi > WiFi Network > Tap Network Name > IP Address

• Tizen Network proxy

Preferences > Network Connections, in all packages (Tizen, Certificates Manager, etc)

• After generating a Certificate profile, re-start the Tizen IDE for the profile to be taken in account.
• To get the devices DUID, go to Device Manager > right-click on the device, then DUID.
• Build Signed Package, then Run or Debug on the device.

Step-by-step, install and run the Hello Tizen example

• In Tizen, New Project > Sample > Next > Wearable > Next > Web Application > Next > General > Hello Tizen > Next > Finish
  • Important Choose a Tizen version matching the target device !! (Frontier is 3.0.0.2)
• On the watch, Settings > About Gear > Debugging, make sure it is on
• On the watch, Settings > Connections > Wi-Fi > Wi-Fi Networks, find your Network and connect to it.
• On the watch, Settings > Connections > Wi-Fi > Wi-Fi Networks, tap network name, and find your IP address.
• In Tizen, Device Manager > Remote Device Manager > Find your device, and make sure in is ON.
• In Tizen, Certificate Manager > create a new Samsung Certificate
  • > Mobile/Wearable
  • > Create a new profile, give it a name
  • > Next
  • > Create a new author certificate
  • > Next
  • > fill the fields, check the "apply the same password for distributor certificate" box
  • > Next
  • > Logging to your Samsung account when prompted > Next (Backup path not mandatory)
  • > Next
  • > Create a new distributor certificate
  • > Enter passwords, and from the Device Manager, for each device (including Emulators you have started before), right-click on the device name, find the DUID
  • > Click the 'Copy' button
  • > Next
  • > Finish
  • > Make sure the certificate is active (checked).
  • > Close.
• If Tizen is running (and it probably is), re-start it.
• In Tizen, right-click on your app (Hello Tizen) > Build signed packaged
• In the menu bar, select the device or the emulator in the drop-down list
• In the menu bar, from the "Run" poplist or from a right-click on the app name > Run (or Debug) as > Tizen Web App
  • You may be prompted for your account password (to be entered twice, follow the instructions in the popup).
  • The app should be installed on your device.
• Try to modify the code, add some console statements, re-build, re-run, and see for yourself!

Quick Personal Note: I found the certificate management a bit challenging...

Note on the screen timeout

The default timeout for the screen to turn off is 15 seconds.

This parameter can be changed in the settings of the watch.

• Settings > Display > Screen timeout, can be set between 10s and 5 min.

REST Requests

Here is a way (and this is just a way, look into the code, look for new Promise) to make a REST GET request to some external resource:

    // Do some REST Request here
    let url = "http://donpedro.lediouris.net/php/weather/reports.v2/json.data.php?type=ALL&period=LAST";
    let xhr = new XMLHttpRequest();

    xhr.onreadystatechange = function() {
        if (xhr.readyState === 4 && xhr.status === 200) {
//          console.log("XHR returns", xhr.responseText);
            let resp = JSON.parse(xhr.responseText);
            if (resp !== undefined && resp.data !== undefined && resp.data.length > 0) {
                console.log(JSON.stringify(resp, null, 2));
            } else {
                console.log(JSON.stringify(resp, null, 2));
            }
        } else {
            let errMess = "XHR: State:" + xhr.status + "\nRS:" + xhr.readyState;
            console.log(errMess);
        }
    };
    xhr.open("GET", url, true);
    xhr.setRequestHeader("Content-type", "application/json");
    xhr.send();
    console.log("Weather data was requested");

Important: Make sure you use "use strict"; if you need (or want) to use ES6 syntax. The IDE seems not to like, it shows arrow functions syntax like () => { ... } as errored, but it works OK, apparently.

As it is a Web Application, your browser's Developer tools are available in debug mode. Very cool.

Note: Look in the code for more elaborated examples of REST requests, also using ES6 Promises.

Note: To store data from one session to another, use localStorage, that works fine. Look in the code, that is the way we store IP addresses and ports...

To check

• Web Socket availability?
• Web Components support for HTML/JS/CSS apps?
