I want to run a long term experiment, where I leave the android phone in one location, untouched, plugged in, collecting data for days (at low enough frequency to keep the data manageable). I'd like to not have the screen have to be constantly on for the entire time. I'm happy to use remote access to monitor it and download the data when complete, but right now, any time an experiment is running, regardless of whether it was started locally or remotely, it keeps the screen on. I can't start an experiment remotely if the screen is off. As soon as I turn the screen off manually (because it won't turn off on its own setting), the experiment stops collecting data.

It may be the case that this is an inherent limitation in Android, but I haven't seen anything in the forums clearly stating that it is.]]>

For that purpose, I use the phyphox.ble library.
No problem to send the packet via BLE.

The problem is that it seems that phypohox can receive only 5 data in a single packet.
(max number of ouptuts in the bluetooth input. characteristic of each ouptut is cddf1002-30f7-4671-8b43-5e40ba53514a)

How to send 2 (or even more) additional data to phyphox?
I tried to cut the data into 2 packets but it seems that phyphox accepts only a single BLE packet.

Thanks for any help.

Would you like to use the accelerometers to plot out the phone’s path? This is for a 2D map, with the device moving on a plane. Of course you can do it for 3D space too, you could perhaps use it to determine how thick a wall is or something. 3d necessary else user tilting will ruin.

When the phone is secured to an object which is moving about, there may be interesting things to see after it is mapped out. The rotation of the phone will have to be factored into the orienteering. I will use the chandler wobble to examplify what users may also find, which is the apparent motion of the earth’s magnetic pole relative to the earth. I have found a number of ways to display it, and users of your app may get the benefit of the depictions for analysing their observations. for this ahplication lets have the phone on a pivot which is parallel with gravity, going around (slow, because the device may be limited to 4g!). There will also be some cumulative error over time (speed, trajectory).


1st depiction: With the phone in rotation, the circumference will need to be resolved to get the plot of the circles. We have the inward reading and the forward reading. initial speeds should be given (will effect the scale), since that is not recorded (defaults: standstill; largest change period; Report the final speed at this setting as a hint), and the forward rate will cumulate on this (presumably it is rise and run from last points, else maybe it is distance away (hypotenuse) and the length of side Opposite or maybe hypotenuse and circumference of the hypotenuse sweep?). The initial trajectory will also need to be given also for the first two points (gap based on initial speed) and each reading will project from the last two.

2nd depiction: To do this on the C.W. I graphed the angle of three points and cumulated it. The result was a downward trend (I added a constant value to straighten it), the C.W. has outward zips.

3: my next idea with the C.W. was to unroll the spiral anticlockwise. The C.W. was one reading per day. The formula for a polygon’s corner angle: A=(S-2)×180÷S. The result was repeating arches (not too interesting).

4: I noticed something peculiar in this and graphed out the speed for both X and Y. (this value subtract last value). This revealed some precession activity, it was drawing another circle, about 433d (i nicknamed it "son of chandler"). My unroll calc is slow so I didn’t bother for too long trying to find a period that would look the best.

5: so I repeat the unroll at 433d and get some concealed data. I presume this is the earth’s crust going about the core (I later thought it was probably going to be a multiple of the moon’s motion, 16×27.33 = 437.3 since there is “orbital resonance”). Shows some oscillations which sometimes die out. I thought the oscillations could be some external influence on the core, moving it about, then leaving it alone. If the mantle gets stirred up then when it is left alone the stirred mantle should act on the core and this causes a phenomenon called gyrostatic precession, which causes the core to tilt. So I predicted when it would tilt again, based on orbits of jupiter and extrapolation of the 2015 data I had, and got August 2018. I was expecting something biggish to happen but here in Australia all that happened was some pilot whales getting beached, one event only (I have not heard of any since… but I don’t always watch the news).
