Read the project's README:https://github.com/mbientlab/MetaWear-SDK-Android#adding-compile-dependency

You can try a hybrid approach where the sensors stream when in range, then switch to logging when connection is lost. Alternatively, depending on how long your tests are, you could just only log data then download it after you are done with that…
-
Log which values are successfully written and what notifications are received from the board before the timeout exception is thrown. Please capture several attempts as well. Again, your issue may be the same as the one discussed in this thread: …
-
Ok, I suppose i'm not subjecting the boards to the same amount of shock as you are in the video. I can try again with a box to jostle the board around.

Your images are not visible. Please post the actual text/code, not a screen shot. The C# SDK has not be tested by MbientLab with Xamarin Forms though another community member has worked on plugging in the necessary files. The issue you are havin…

* Depends on your use case. What are you planning on using the sensors for? * Again, depends on what you are using the sensors for. If they are acting as beacons, the hubs don't need to do anything other than continually scan for the ad packets. …
-
* Can you provide some data that illustrates these wide swings? * How are you configuring the sensor fusion algorithm? The algorithm will calibrate itself once started so there is no configuration to store.

Which platform are you using the app on?

See the below post:http://mbientlab.com/community/discussion/comment/1923/#Comment_1923 In general, battery life can be on the order of weeks to months depending on your use case i.e. streaming IMU data vs. polling environmental data every 30 m…

If you pick MetaCloud to store your sensor data, use the APIs provided by MbientLab. If you want to use another cloud service, use their APIs instead.

Again, how are you using the app prior to seeing this disconnect issue? It is most likely the Bluetooth stack of those vendor specific Android builds. I can't tell for certain as we don't have any of those phones in the office. The devices we do…

yes

You can read the documentation and checkout the tutorials: https://mbientlab.com/androiddocs/3 https://mbientlab.com/tutorials/JavaAPIs.html#template-apphttps://github.com/mbientlab/MetaWear-Tutorial-Android

The MetaWear app is available on GitHub.https://github.com/mbientlab/MetaWear-SampleApp-Android How are you using the app prior to these disconnect issues? Those are status codes from the Android Bluetooth stack. You can look them up in th…

Based on the log output, it looks like the tablet needs more time to wait for a response from the remote device. The latest Android SDK has an increased timeout period so I'd try updating your compile dependency.
-
Timestamps should be OK with 1 reset. It's multiple resets without re-establishing connection that will result in time sync issues with the SDK.
-
Ah, then yes you can but you will have to write your own app to do so. What platform are you developing on?
-
Post a stack trace of the crash and steps to reproduce said crash.

So then the y-axis plots ADC values.

I do not need a video of all 18 boards; pick one and record the test procedure that shows it being woken up from movement. I have yet to find a board that exhibits this behavior have no idea if any of the boards we have in inventory will exhibit t…

Are you using that device with both Android 4.4 and 6.0? The code works fine on my Android x86 VM and Nexus 5. Try using another Android device.
-
Use the streaming feature instead of the log/download feature.
-
Depends on what type of gpio data you are plotting: adc value, voltage, or digital state.
-
Please directly contact customer support for the updated files.http://mbientlab.com/contact Also, posting your email in plain text on a public forum generally is not a good idea.
-
Yes, use the MetaBase app. http://mbientlab.com/tutorials/Apps.html

Hrm, well the only difference with older pymetawear versions and the current Python SDKs is the underlying Python ble library. We use a custom fork of pygattlib, which you can find here https://github.com/mbientlab/pygattlib Are these connec…

What do you mean by "moved them all"? Are you spinning them, dropping them, sliding them on the table, or something else? How long does it take for the 18 devices to start advertising? Since you have 18 devices that aren't working, post a vid…

Are you running as superuser?

What Android device and OS version are you running? It's highly odd that both Android and iOS are failing to find the device to create a log session. Are you familiar / comfortable with Android development? If so, plug in your Android device and…
