The "StarterApp" project is a template for creating UWP apps with the C# SDK. It pairs with the tutorial that shows you how to stream accelerometer data (https://mbientlab.com/tutorials/CSAPIs.html#xaml-layout) and serves as a general starting poin…

Your code is not reading analog values; all it's doing is printing the pointer address of the object representing analog data. You have to first subscribe to the data signal then issue read commands for each data sample. https://mbientlab.com/cpp…

Post the full metawear code you are using.

Post the metawear code you are calling. Also, what android os and device are you using?
-
No, there are no plans for a Windows version of the Python SDK. You should use the C# SDK for Windows development. Using a virtual machine to run Linux will work provided your VM app supports hardware passthrough.

The Android SDK has the sleep mode function available in the Debug module. The iOS SDK exposes sleep mode in its internal modules which will require adding the SDK directly from GitHub. Basically, you just need to enable sleep mode then reset the …

* Which tutorial are you referring to? The link you provided is the source code of the current C# SDK. * The solution is for Visual Studio 2017, not 2015. * Which part exactly is unclear to you? The tutorial solution I linked has full working …

A release candidate to fix the power consumption is now available. You can upload it to your board with the Android or iOS MetaWear apps.
-
I'm not suggesting you poll the values. I'm telling you to read the analog values to confirm if my hypothesis is true for the closed and open switch states.

This sounds like this is an issue with Noble and it would be better to ask this question on the Noble GitHub page. Before that, create a new JS project that only uses Noble to connect, perform a service discovery, then disconnect, and see if you ge…

Ah, that video is for the old C# library that was just a wrapper around a shared C++ library and should have been removed. Samples projects for VS2017 can be found here:https://github.com/mbientlab/MetaWear-Tutorial-CSharp
-
Pin 5 is ground so I would not expect there to be any input changes whether your switch is open or not. You can check this by reading the analog values for both close and open states.
-
Can you try to isolate what the differences in your tests were that resulted in the different Euler angles? I've forwarded the data to the firmware developer so maybe he can provide more insight to this issue. It would also be interesting to see i…

What MetaWear code are you running?

The stacktrace of your crash indicates an error with the underlying native code. native: pc 000000000003aba4 /system/lib/libc.so (tgkill+12) native: pc 0000000000017cb5 /system/lib/libc.so (pthread_kill+52) native: pc 00000000000188c7 /…

* How often does this problem appear? * Can you reliable reproduce the issue? * How were you using the board prior to receiving this error message You can try connecting to the board again or resetting the Bluetooth adapter.

The pin number on the pin diagram is not the same as the GPIO pin numbering. Pin 3 corresponds to GPIO pin 1.

It has not been tested with Python3. If you need a working version for Python3 right now, clone the repo and replace the 'sets' package with a Python 2.7 and Python3 compatible way of creating a set: https://github.com/mbientlab/MetaWear-SDK-Pyth…

No, the data will come as two separate samples. You can post process the data in your app to match whatever format your need.
-
Hrm, so looking at the log output, the board does connect but it fails at the service discovery portion. Try creating a blank app that only has a "connect" and "disconnect' button and see if your Android device can repeatedly connect/disconnect wit…

* Can you post the MetaWear code you are calling? * Do you have your external sensor properly wired to the GPIO pins? * Does the GPIO data work as expected if you are testing with the Android or iOS sample apps? * https://itunes.apple.com/us/app…

See the sampleFrequency variable in the MBLMagnetometerBMM150 interface.
-
What is log output displayed in Logcat during the connection attempts? Is the board at least able to connect with the Android device? Are you stopping the streams before disconnecting?
-
yes and yes
-
Hrm, I wonder if this is simply just a misunderstanding of which axes are pitch, roll, and yaw, see:https://mbientlab.com/community/discussion/comment/4632/#Comment_4632

Which SDK are you using?
-
Please put unrelated questions in their own thread.

Outside of hardware changes, you can either 1) reduce the sampling frequency or 2) right shift the data by 1 byte to compact the data. No, the boards presently available only allow power through USB. Enabling data transfer through the USB port …

* There are no log files. When you request a log download, the data is delivered as is to the host device. What you do with the received data is up to you. * By default, the logger will stop recording. You can enable overwriting if you want.

What firmware is the board running and what is its hardware revision?
