BLE_CONNECTION_UNAVAILABLE when making webRequest from background process (Venu sq)

Hello.

I am currently making a widget, which i would like to fetch some data from a API every twenty minutes... When i make the web request when the watch is "awake" it works like a charm, but when i try to make the same webrequest from a background process, i constantly get responsecode -104 (BLE_CONNECTION_UNAVAILABLE). I Assume the problem is linked to the fact that i cannot find my device (Venu SQ) under supported devices, in the BLE section in the documentation. However i am looking for a workaround?

Is there any way to establish a bt connection (not BLE), or any way to "trick" the watch into thinking it is in awake mode?
I know that will be on behalf on the battery, but i am okay with that.

Best regards
Malthe Reipurth

That is what you see when the watch isn't connected to the phone (normal pairing). This has nothing to do with the connect IQ "BluetoothLowEnergy", and support for that on a Venu Sq.

It should…

It should have nothing to do if the watch display is on or off

What could the explenation be then?

Like i said, there is no problems what so ever, when i do the request when the display is turned on.

it could be your phone dropped the connection and that can happen based on the type of phone, or GCM on the phone isn't running. You can check if the phone is connected with System.getDeviceSettings()..phoneConnected, but there's really nothing you can do if it's false other than try again later.

That makes sence..

Would it take up to much battery if i started a listener to check if the phone is connected (Let's say every 10 seconds)?

With a background process a temporal event only runs at most every 5 minutes.

With a widget running in the foreground, it will time out and return to the watchface in 30 seconds to about 2 minutes (you don't see this in the sim)

You might find something in the venu sq forum about why you keep losing connection

Sadly i have already searched this forum.

I don't think "loosing" connection is the propper term to use.
I have never expireienced a time offset with notifications or anything like that..

It only seems to effect the makeWebRequest.

Here's one of my widgets that does a makeWebRequest and as far as I've heard, no problems on a venu SQ.

The description tells you how to get a free API Key for Open Weather Maps.

It's a bit of a hybrid when it comes to comm, in that it has a background that runs every 15 minutes, but will also do a request from the widget itself if there is no current data.

It's really similar to this one

But getting an API key from Weather Undergroud requires you have a weather station that sends them data.

I see. Is this open source? (Where can i see the source code?)

0 jim_m_58 over 4 years ago in reply to 7550855

None of my apps are open source.

It's more that you can try the widget and see if it works for you.
