Returning to app after using makeWebRequest using Sync - over Wi-Fi using the 3.1 Toybox.Communications.SyncDelegate.

Hi, I'm using direct connection to wifi to get data from a web service (without being connected to a mobile phone). All works really well and I can start sync, gather data and display it on my device, but I don't quite follow what happens when I send notifySyncComplete and how to correctly resume my widget app.

The limited info available says - 'The Sync UI will be popped off the stack returning you to your app'.

However I get left on the sync complete view and I'm not sure what state my app (widget in this case) is in.

Are there examples or instructions on the correct flow here ? Any help appreciated. Cheers.

In Connect IQ 3.1 device apps now can initiate network requests over Wi-Fi using the new Toybox.Communications.SyncDelegate. Here’s how:

In your app, call Toybox.Communications.startSync
The system will call getSyncDelegate() to get your Toybox.Communications.SyncDelegate subclass
The device UI will go to a sync screen
In onStartSync make your first call to Toybox.Communications.makeWebRequest
Request one item at a time, triggering each makeWebRequest in the callback of the previous one
Call notifySyncProgress to advance the progress bar
If onStopSync is called, handle shutdown of your sync
When you have downloaded all items, call notifySyncComplete. Pass in null if you completed successfully or pass in a string if you need to display an error message
The Sync UI will be popped off the stack returning you to your app

The "back" is popping the view. That's the default when "onBack" isn't in your code.

Submit a bug report and indicate if this is in the sim or the real device, and which device. You may want to see if this happens in the bulk download SDK example and note that, or provide code to replicate it.

Thanks for your advice, I will raise the bug report.

For reference - It happens in the SIM, and for me it is 945. I checked the Bulk Download SDK example (which is Fenix 5), and observe the same behaviour (of course, it is less clear if this is the intended behaviour for the SDK Example).

Here is the SDK example in SIM, with screen grab, after the download completes, it sits on this view and the buttons do not operate. It's the equivalent I found in my application. I appreciate that there may be some action that was intended from the App to exit the Sync and resume App.

At that point in the sample, pressing back take you to the app's main view

Great info; thanks!

Did you start from any of the samples (I haven't pulled them down and looked yet) or roll your own from the API docs and add SyncDelegate?

I know the capability I wan't, but I'm a terrible designer, so if there's a "nice" widget or app already.

I'm thinking I want to cheat by building my HTTP request in to something that's already visually appealing!
