No, you will never have all data at equally spaced time intervals from the boards. The IMU itself does not always produce data at the exact timing and the firmware has to mark each data sample with a value used by the SDKs to calculate the actual …

Currently no, the haptic driver only runs for the set time then stops. The typically use case is to drive a buzzer or motor to provide haptic feedback.

I tried streaming illuminance data from a MetaTracker in the office and I am not able to reproduce your issue using the same settings and with the app. At this point, I am not sure what could be the problem given that everything is working fine on …

* What modifications did you make? * Does the standard test app, without your modifications, work as is? * Can you log / download data with the MetaBase app? * https://itunes.apple.com/us/app/metabase/id1088416232?mt=8

You will never have all of the data be equally spaced at the set ODR. Furthermore, the few time differences you have posted, and I assume this is true of the other values as well, are approximately +/-1% of 0.04s, which is expected.

I know the boards work after a hard reset. My question is to see if the MetaBase app works without the same issues from the MetaWear app. If the board is in a bugged state after using the MetaWear app, it won't work with MetaBase so of course it m…
-
Which app are you using to log the data?
-
I haven't had a chance to look into this further. Will try to get around to this by the week's end.
-
Yes, you are correct that mounting position is important. I assumed you were mounting the board at the center of axis but clearly that is not the case as stated in your first post. Back to the original question, I am not aware of any py lib that …
-
Are you logging or streaming? It sounds like you are logging 50Hz then 800Hz, and streaming at 100Hz at a different time. Also, which board are you using?
-
The gyro report angular velocity in degrees per second. A simple unit conversion to rpm should suffice.
-
There's no documentation available per say other than the APIs. You can checkout the unit tests of the various APIs to see what byte arrays are expected for the commands and responses. https://github.com/mbientlab/MetaWear-SDK-CSharp/tree/master/M…

i don't see any gyro code in above code snippet. What have you tried thus far and what exactly was wrong with the code?
-
I believe it is ~1M ambient light data points (2^20). 500K is regarding acc, gyro, and mag data.
-
Ah yea, I've never had much luck with pygatt, always stuck with pybluez. Glad to hear everything is sorted out.
-
Not sure why the dialog won't pop up after you resume the app. Maybe the board isn't connected when the app is resumed? Add log calls / breakpoints to your code to see if there are any differences in the code flow before and after you put it in th…
-
What if you boot the board in MetaBoot mode (insert battery while holding down the button)? Are you running any iOS test apps on your mobile device?
-
Hrm...in your android code, can you log the result of the bytes method in the Subscriber? Log.i("myapp", Arrays.toString(data.bytes()));
-
* Are you streaming 6 devices at once to one adapter? * What device / OS are you using? * In your tests, what was the max stable distance between the sensor and host device? You need to provide more details about your setup and use case, and …
-
What values are you getting from the iOS app? Also, what I mean is how is the sensor itself being used? Are you simply shining a light on it or doing something more complex?
-
Can you post the debug output from one of the example scripts you were running?
-
Try doing a firmware update.
-
Use the MetaWear app to connect to and use the board.
-
How were you using the board before this happened?
-
That is not supported in the iOS SDK.
-
Please provide board specs and light sensor settings. How long does it take for the values to drop to 0? Is it as fast as shown in your screen shot? How are you using the sensor?
-
That is taken care of in the MainActivityFragment class:https://github.com/mbientlab/MetaWear-Tutorial-Android/blob/master/multimw/src/main/java/com/mbientlab/metawear/tutorial/multimw/MainActivityFragment.java#L124 Have you read through the An…
-
The firmware should be available next week after we have updated the various SDKs and tested the new features.
-
Which Samsung and Moto models? Your previous post stated MetaBase worked fine, but now you just said MetaBase is not working? What settings are you configuring the sensors with?
-
You'll have to provide more details. * Again, what specifically about the code is unclear to you? * What is displayed in Logcat when this happens? * What Android device and OS are you using? * Can you successfully connect 2 boards with the MetaBa…
