NightWatch Delta values have incorrect sign. about nightwatch

[AdrianLxM]

Does this happen with every delta? Does it always show exactly the negated sign or does it show another delta value as well?
What version of xDrip and what version of NightWatch are you using?

[Hebes24]

Correct Value, incorrect sign (literally a '+' when there should be a '-', and vice versa). Also, the arrow is in the correct direction and the graph displays correctly.

Using xDrip 2.0.3a and NightWatch 2.0.3.

Do you have NightScout and xDrip on the same phone? In this case you could check if the delta is correct with local broadcasts instead of going via the share server.

I think I found the bug. Thanks for reporting! I will try to fix it until monday.
@Hebes24, would you like to test it (I have no Share)? If yes, do you self-compile or do you need an .apk?

Note for fixing this: https://github.com/StephenBlackWasAlreadyTaken/NightWatch/blob/master/mobile/src/main/java/com/dexdrip/stephenblack/nightwatch/sharemodels/ShareGlucose.java#L102:
bg.sgv_double() - currentValue should be: currentValue - bg.sgv_double().

[Hebes24]

I'd be happy to test it. I would need an .apk for that.

How do you setup the local broadcast? I am running both apps on the same phone, and I saw the option for it in xDrip to turn it on, but I was unsure of how to configure NightWatch to work with it. If it's simple enough I'd probably end up using that, since it sounds like I'd be able to cut out the Share servers, which would streamline my process (effectively eliminating the middleman).

Thanks for your responses!

[AdrianLxM]

@Hebes24, if you enable local broadcast in xDrip and disable that you get the values from Share, NightWatch will automatically show you the values.
No need to waste mobile data. And: Values on the watch when there is bad cell coverage :)

[Hebes24]

Wow, that's simple. Almost makes me feel silly for thinking uploading to Share was the only way to get this to work, haha.

I switched to that method and the deltas look correct. I'd still be willing to test out the fix for Share though if you still need assistance with that.

[AdrianLxM]

Thanks @Hebes24. I'll come back to you and pick you up on this offer. Glad there was an easy solution for you.

[Hebes24]

Me too! And Thanks for developing these apps. It's really taken my CGM experience to a new level. I really appreciate it!

I've been using the NW 2.0.3 apk download from the project site and I've been noticing the reversed (+/-) sign issue as well. I get the data from the Dexcom share account and would be thrilled to test future releases if provided an APK. Great App! I'm a big fan of the falling fast alarm. Very helpful.

[AdrianLxM]

Ha, sorry, I forgot. I'll put it on my todo list again. Thanks for reminding me.

I am also having a reverse sign issue. I am using dexcom server for data. I'm really not tech savvy, so what can I do to fix?

[AdrianLxM]

@Hebes24 @bw396704 @ryanchen26
I've created an apk with a fixed version. It would be great if you could test it and give a quick feedback:

Just did and appears to be working now. Thank you so much!

[AdrianLxM]

I made this apk to the latest beta version. There were so many fixes and the adoption to Android Marshmallow already waiting to be release: Download Page

Looks great, well done!
