Same use as me Mr So.
I have changed the hive indents in my hive manager to match the first two pairs of the MAC address on the three I have been testing.
Not ideal but workable.
What op sys version are your devices running?
I picked up a cheapo tablet running 5.1 and it crashes out instantly.

Hi Motobinman, both devices are on Android 6.0.1, I can leave CentriaRuuvitag scanning for hours before it stops working and then I just have to reopen it and it is fine again.

(problem actually was with Androidās Base64 parsing, with new data format it decoding always caused exception, not sure)

i went out and bought a used Samsung S5 upgraded it to Android 6 and it runs fine.
So now I have to carry two bloody phones.
Isnāt technology wonderful
Was hoping for a simple temp and humidity app with logging and no need for internet access for iphone/ iPad. Fat chance of that it seems. š

Guys, Iāll put someone in charge of investigating these issues. For internet connection, for sure it can be done, but in our use we needed that one. But its easy to make version that does not use internet connect. For crashing, I have hard time while replicating this, but let see what our guys can doā¦

We will update the app, but at the moment we have no resources to do it. Community support is welcome as all code is in Github

We have now started working with the update, if you have ideas/feature requests, please let me know. I think we are dropping requirement for internet/GPS in first release, this makes app much more usable and more āstandaloneā. Those features (with configurable URL for backend) might be added later. Iāll keep forum updated on our progress and will send you some pre-release versions

Great!
For us who have several RuuviTags at one location it would be nice if we could give the tags friendly names so we donāt have to remember which MAC address is which tag.
Looking forward to try the new version.

I see that the humidity get changed, but should it not be with rawData[3]?, in
Ruuvitag.java.
```
// humidity = (rawData[3]) * 0.5;
humidity = ((float) (rawData[1] & 0xFF)) / 2f;
```
I also see that it is 17 dayes since the RuuvitagScanner.apk is updatet.
Is there a dukoment somewhere, that explan how to make the apk?

@anon24749318, weāll try to update APK during the weekend and fix that RawData Humidity too.
