BLE host timeout

Former Member over 5 years ago

I am programming a widget that requests data from an api using makeWebRequest (https://apps.garmin.com/de-DE/apps/a35c4812-cac9-49da-8e70-29cd9fc44e1e). I and also some users get the error -2 which, according to the documentation, means BLE host timeout. Does this mean something with the smartphone is not working? I have the latest GCM version for android installed.

It seems like the error only happens when the screen of the smartphone is turned off, but GCM has the permission to run in background.

Is someone experiencing something similar? This is a very annoying bug and I am pretty sure this happens at garmins code somewhere.

I'll see a -2 at times if I'm right at the BT range from the phone. It means the watch hasn't seen a response before a timeout. Could it be that the server you're accessing is really slow?…

I think it does not have to do with the distance between the device and the smartphone as it happens when they are really close to each other.

The server is a really good point, I am using a free service which shuts down my server if it is not needed to save resources. Maybe the restart takes too much time.

But this does not explain why this error only happens when the display of the smartphone is turned off?

The screen part could be specific to your phone (brand) and the version of Android. I have a samsung, as well as a few apps/widgets/watch faces that do makeWebRequests, with no problem if the phone's display goes to sleep.
