Re: [Interest] Qt positioning

[Jason H]

Hi, 

 

What is the status of this? I'm at a point now where the feature using positioning is on the radar.

 

Many thanks.

Hi Maurice, hi Jason.

 

Thanks for your responses.

I have tested successfully position code previously and it worked. So did one of our customers on an app of mine (android devices). For such reasons I was concerned for what was going wrong yesterday. Then I got the difference: I was using another device! I've tested the one I've used previously and everything worked like a charm. I got the position in less than a second or so.

 

Given this result (and the positive results of our customers on Galaxy SX phones) I've tested other devices at work: a galaxy tab 2 and a lenovo A806. The former has stock android whereas the latter has been rooted and flashed with AOSP. Neither of the two returned a value, nor timeout was hit. 

 

I plan on reply with the exact results of my tests as soon as I have time to test other devices. I'll also test the examples for sure.

 

Thanks again,

F.

Did you check with the examples provided in the module? If those do not work for you either, then it's time to open a bugreport soon, so that it might get fixed for 5.5.1 then.
