The metawear boards come with 3v gpio pins that can be connected to external sensors. You can use the apis to read the analog or digital values from the sensor. Refer to the product specification for gpio pin locations: https://mbientlab.com/docs/…

How long is "some time"? I enabled ibeacon mode on an rpro for 8 hours and it advertised fine all day. Did you use a fresh battery during your tests?
-
No, the chip does not report the magnitude of the interrupt, only which axis triggered a high-g interrupt.
-
Do you see the "connected" message in log cat? The freefall app automatically attempts to connect to a board when it starts.
-
What board are you using and how fast are you streaming the data?
-
We have experimented with a watchdog however there are still lingering issues with it such as attempting to do a firmware update while the watchdog is active.
-
What OS is your tablet running? Try using the nRF Connect app to scan and connect to the boards. If the boards aren't usable with the Nordic app, you should try getting your hands on another Android device. https://play.google.com/store/apps/d…

You can import one Switch class and use the fully qualified name for the other class.

All Android apps are written in Java with the Android API.

yes

When using sensor fusion, do not configure the senors yourself; the algorithm will configure them depending on the selected fusion mode. You can refer to this table from the Android documentation for sampling frequencies.:https://mbientlab.com/andr…

@aduvidi We just released a firmware update to address this issue
-
Firmware v1.3.1 has been released to address a critical bug with v1.3.0 release. See OP for specifics.
-
MetaMotion R falls under the category of "other boards"; it is not the same as a MetaWear R board.
-
You can now update to this firmware now with the current iOS app. There is an app update pending approval that adds support for the sensor fusion data and once the app is live, you will need to use that release to update to this firmware and use se…
-
The iOS app should automatically update the board once it detects the firmware is out of date. What happens when you connect with your board?
-
8g for MetaWear R boards, 16g for all other boards
-
Python would probably be easier at this point. One of our community members, hbldh, has created a Python package to use the C++ API. You can check that out on PyPi.

I presume your Nexus 7 is running Android M? We have two Nexus 7s (Android 5.0 and 4.4) and I've noticed that the Bluetooth radio is slow when the app is run in debug mode however they were never slow to the point of having to wait over a minute fo…

I have only found Bluetooth LE tutorials for Universal Windows apps written in C#, which is what the UWP Starter project is based on. The only resource for using BLE in a Win32 app is sample code from the MSDN forums linked by another community mem…

You can assume the data is being produced at the ODR specified when configuring the sensors. As to your second point, does the gyro accurately report data if it is the only active sensor? Is there a difference in behavior when using the normal …

@aduvidi The bug mentioned in this thread is for older boards which use a different SOC than the MetaMotion boards. We are testing a fix to address the issue you and others have reported with the metamotion boards.
-
What OS and language are you planning on using?
-
Checkout the "Operational Parameters" and "Sensors" section of the FAQ.
-
No, readBatteryState is a different function from readBatteryLevel. You can read up about it in the documentation.
-
I can still see Manufacturer ID with the nRF Connect (Android) app when using firmware v1.2.5.
-
Unfortunately I have no experience with Unity nor game development on the Android platform. so all I can do is point you to some resources that may help you. Jar files of the Android API can be directly downloaded from GitHub. Alternatively, we al…
-
iOS docs have been restored. Yes, we are working to get the sensor fusion algorithm released asap. Expect a firmware update soon.
-
Yes that is the expected behavior as the firmware is utilizing the full 20 bytes allocated for a bluetooth le packet. Does this fix the lockup issue you described?
