Fugit185 saysL:I have a tablet that reads information all the time. The downside of a mobile phone is that it is usually included, so the connection is lost.
Look, how does that app relate to local storage? Of course, it can be controlled from there, but shouldn’t the actual recording take place inside the device? So you need a new iron version?
Otso responded: Data storage in the device can also be done with a software update, i.e. it is enough to update the tag’s firmware. You can do it with a mobile phone.

Maybe I wrote a little unclearly. So I meant a buffer-like transmission when the tag is out of range. That is, it would then send the missing data for e.g. a day or two when the connection is found.
You have to wait for the official firmwares so there won’t be any other problems. In these open source projects, it often seems to happen that something is achieved, but at the same time there are new problems.
My project has progressed as follows. I had an old Raspberry Pi B-model in the box, I put a Bluethooth LE USB dongle on it and it now collects that data. However, it doesn’t reach that outhouse either. I installed influx and grafana and data collection java on the Pi.
I learned a lot of new things, e.g. this Influx database was new to me, and I had never used that Granafa before. Now they bend too!!
Thanks for the good instructions
Fugit185 asked:ok, how much data can it hold?
So the latest mobile software can request stored data and then show it as history?
Where is that done as a TSI? With a rasp? With Node-red?
Otso responded: In the last version, 1024 samples, or about 3.5 days every 5 minutes.
On iOS yes, on Android it’s still a work in progress.
There is nothing official about this, for my own development work I made a web-bluetooth page that can read the data. The page is at OjousimaRuuviwebbleTs 57 and the source codes are GitHub - ojousima/ojousima.ruuviwebble.ts: Angular and typescript project to communicate with RuuviTags over Nordic UART Service. For my own experiments only, no support is given 18
In practice, if you want to make the RP read data, you have to code it yourself, there is no ready-made piece.
Fugit185 acknowledge :thank you
i try
Mrkus_T askes: Interesting. Does the iOS version also forward the missing information via the “gateway”?
