Des NT have Accelerometer and Gyroscope or not? - Barnes & Noble Nook Tablet

There seems to be misinformation regarding accelerometer or gyroscope is included or not. Officially, it is not a listed feature on B&N's website, can anyone confirm this? I'm trying to figure out how they can turn epubs into landscape view now whereas in v1.3 NC can't do it.
Thanks.

I may be wrong but looking at the system info in quadrant indicates it does have both accel semsors amd a gyroscope sensor. I believe it does.

Not to hijack, but while we're on the topic of chips that are or not included on the NT, Bluetooth? Bluetooth antenna? iFixit has posted a tear down, but mentioned nothing about the wireless chip(s) in use.

The Android Market has a very nice app called AndroSensor. It breaks out all the standard Android sensors and gives their readout.
A good candidate for side-load maybe?
My NT is sitting here - nicely wrapped - until Christmas... All I can do is stare at it.

Downloaded, tested it out:
Orientation: No Senor Found
Acceleration: kxtf9_accel version 1 (about the readout bars it says sensor_status_unreliable but does move based of me moving the tablet)
Magetic Field: HMC5843 3-axis magnetometer (the readout bars do not change at all)
Light: BH1780gli Light Sensor (once again, has the sensor but is not in use as the bar does not change)
Proximity: SFH7741 Proximity Sensor (readout bar does not change)
Pressure: BMP085 Pressure Sensor (nothing on the bar)
Temperature: BMP085 Temperature Sensor (nothing on the bar but I would assume this is normal for a temp sensor)
Here are additional sensors it does not show in the regular tabs:
Rotation Vectory Sensor
Linear Acceleration sensor
Gravity Sensor
All 3 above show UNKNOWN_TYPE 9, 10, and 11 respectively.
Also, I just downloaded xplane from the market...tested it out and works fine. Xplane relies on an accelerometer so we can confirm it does have one.

(edit) ^^ Beat me to it!
OK, here is what androsensor reports:
Orientation: No Sensor Found
Acceleration: kxtf9_accell, Version 1
Magnetic Field: HMC5843 3-Axis Magnetometer, Version 1
Light: BH1780gli Light Sensor, Version 1
Proximity: SFH7741 Proximity Sensor, Version 1
Pressure: BMP085 Pressure sensor, Version 1
Temp: BMP085 Temperature sensor, Version 1

So no gyroscope just like NC and only accelerometer in both. Thanks!

And still no clue about BT. We need some input from a tear-down...

[Q] Difference: Proximity and Ambient light Sensor

Hi,
What ist the difference between the Proximity Sensor and the Ambient Light Sensor?
I know, the output of the Ambient Light Sensor depends on the ambient light
but what is the proximity Sensor? How does it work on the HD2? What are the output values etc?
And: what is the main use for it?
The proximity sensor uses IR light to detect when an object is close to it. In the case of a mobile phone it uses this information so the screen can be turned off when the proximity sensor notices your head (or more accurately, your ear) which may inadvertently press on the screen when making a call. As far as the output values? I have no idea.

Gyro Sensor calibration in settings - Dot not moving ? Normal ? Someone try :)

Ok in the galaxy s2. If you go to settings, display, then at the bottom, you have horizontal calibration and gyro sensor calibration.
If you choose horizontal calibration you get a little test thing with the dot in the middle and it moves as you tilt the device.
When I go to gyro sensor calibration the dot just stays in the middle and does not move. Is this normal ?
Can someone try the above please
yep i tried this before, same here, but i think it's normal
If you look two different calibrations .
jje
I know, but shouldn't the dot move when you tilt the device. I thought thats what the gyro does
Do it while you are in the car (as a passenger), and see if that move when the car accelerates or slows down
Why would one calibration act the same as another .
jje
I am having the same problem the gyro calibration was working till i click on calibrate as soon as i clicked it i no longer see the ball moving :/ tried wiping and everything nothing worked.
Mine doesn't move either.
I could of sworn mine was moving last time I checked! Very strange..
I cant get mine to move either.
Maybe this might help.

the gyro problem is annoying .. every app just turn into landscape mode :/
hope someone fix it fast ;/

Lite'ning rom , it was working untill i clicked on calibrate after clicking it it got stuck :/ well that me i don't know about the OP.
I have the same problem (indications for gyro callibration) but also a magnetic sensor problem (see this http://forum.xda-developers.com/showthread.php?t=1111355 threat)
I used an app called sensor test / plot which shows problems with the magnetic sensor and orientation.
Anyone having the same problem?
Try an App called GPS status, it displays the output of all the GS2s sensors on one screen, including satellites, compass, gyro and accelerometer, at least you can reassure yourselves that the various sensors are actually working

All the numbers move for me using the sensor test/plot app.
in sensor test everything is working but the phone just stay in landscape mode .. thats the problem that i have.
You can try *#0*# on your dialler and then use the Sensor test and check if everything is all right.
tested on *#0*#it says its working fine as well .. :/
Recently my magnetic sensor did not work. Yesterday suddenly it came to life exept I don't trust it.
Just to check if my sensors are OK I would like to compare some data. I use *#0*# and the SENSOR
My readings are (when on table):
ACCELEROMETER Sensor Raw Data
x:-10/10 y:-20/-40 z:3030/3060
Gyroscope Sensor
Y:-0.01/-1.00 P:0.01/0.80 R:0.01/0.90
Gyro self test OK, Graph shows normal plot with rotation around all axes)
Magnetic Sensor
Magnetic: x:-45 y:-600 z:1086 (values change with orientation but stay around the same range, exept for the z value, it stays at 1086.48 contantly)
Azimuth: 176 (changes just +/-2 degr with rotation and +/- 20 degr with roll)
Pitch: 0,050 (changes normal with pitch)
Roll: 0,40 (changes normal with roll)
Little compass indicates South (red line towards you) and does not change with rotation (just +/- 20 degr with roll). It also says need for calibration and the number 0.
I know values will be different with everyone but should be around the same range. I have values (Accelerometer) in the 10 / 30 and 3000 range depending on de axis. Same with the Magnetic sensor 50 /600 and 1080 range.
As the magnetic z-axis value is stuck I expect a faulty sensor.
the test is all good to me but the image test it failed to move from landscape to normal. hope someone can help :/

[Q] CM7 sensors working?

Does the current CM7 build restore functionality to the Proximity and Orientation sensors to the point where they can be used with standard apps?
Does the NT have a proximity sensor? I did not think so.

Just going by statistics from a couple of apps i.e. Android Assistant which purports to give Name, Vendor, Range Resolution and Power data for installed hardware as follows. (list not complete)
Proximity Sensor - SFH7741 By OSRAM
Rotation Vector Sensor - Google Inc
Temperature and Pressure Sensor - PMP085 by Bosh
Magnetic Field Sensor - HMC5843 Magnetometer By Honeywell
Linear Acceleration Sensor - Google Inc.
Light Sensor - BH1780gli By ROHM
Gravity Sensor - Google Inc.
Accelerometer Sensor - kxtf9_accel by kxtf9
No Gyroscope Sensor or Orientation Sensor listed
My error on the Orientation Sensor I should have said, and am most interested in, the Magnetic Field Sensor
Other apps report similar hardware available.
Besides the holy grail of Bluetooth, I was wondering if the CM7 versions have been able to natively find and activate them (if they in fact exist) or if each had to be detected and programing specially written.
Another possibility is that other necessary hardware was never included to utilize all the sensors.
In other words...
Has anyone with the latest CM7 root tried and successfully to run a compass program? I am happy with my simple Nook and Zergy root with BN access but would build a new SD card if I had a working compass for some astronomy apps.
Thanks for any additional info.
I tried a compass on CM9 and got a magnetic sensor error.

Screebl Pro doesn't work on CM7 alpha final.
I think you need to wait for next update...
Odd thing that Screebl doesn't work. I would think that it would use the same sensor for angle identification that other programs do. For instance a nice little program called Skeye can show you the night sky when you and change the vertical angle and/or rotate from portrait to landscape but it does not recognize rotation to different compass points apparently because there is no driver for the magnetic field sensor.
It appears that in my list of sensors above that anything listed with a Google driver is functional. Those without are not. But given that the manufacture of the sensor is listed, there might be Google drivers available that can activate them.
Thanks to those that did some testing

Incompatible sensors in the Evo LTE?

I've tried several different apps that report sensor data from the Evo LTE, and almost all of the sensors show no data.
Only things like the proximity sensor, light and sound register data.
The orientation sensor and compass sensor show nothing and the accelerometer shows almost no changes as I move the phone around.
The Compass app always shows North.
And yet... Google sky maps works perfectly.
I wanted to use the orientation sensor to control some servos on an arduino project like I had been with my old Evo 4G.
Have they changed the APIs, or are they using some new chipset that (almost) all the apps don't yet understand?
Use elixir 2 to test the sensors

Hmm -
Compass (Catch.com) and Compass Pro are stuck on North.
Compass & Level shows North and always centered level
Smart Compass and Compass (Droidware UK) are showing the actual direction.
Labirynth light works.
Google Sky Map works.
Elixir 2 shows:
Accelerometer: seems to be working
Gravity sensor: nothing
Gyroscope: nothing
Light sensor: works
Linear acceleration sensor: nothing
Magnetic field sensor: works
Microphone: works
Orientation sensor: nothing
Proximity sensor: works
Rotation vector sensor: nothing

Using a rom of some sort? Possibly it has broken things.
Everything checks out for me in elixir. Go have sprint run their tests on your device. Sounds like yours needs replacement

Do you think maybe sensor tests are a bit esoteric for your basic Sprint store?

Any store with a service department has a wide assortment of tests. All they have to do is plug it in

Gyro/compass and photosphere

Does anyone know how photosphere can be fixed to recognize properly the gyro and compass sensors? I've tried several roms and 4.2 camera versions and on my phone the horizontal motion is not detected at all and the vertical motion is averaged badly (~15s). So I assume there is a setting somewhere or a device link that needs to be made so that photosphere recognizes the gyro and another setting somewhere else for the time averaging constant.
Panorama works ok and that [I think] it relies as well on the gyro.
Yes, I tried GPS Status calibration, letting the phone on a flat surface with photosphere turned on, extreme rotations around all axes.
The razr doesn't have drivers for a gyroscope, just compass and accelerometer so photosphere will never work.

But opening GPS Sensor and Turbo GPS I see the absolute radial tracking is correct. Google sky works and so does panorama. I assume by this that the gyro (measuring speed of rotation) is not really needed since it can be determined from differentiating the magnetometer.
Maybe a custom device driver can be built that emulates this? Would be interested in doing this.
