Sampling rate is fixed depending on the sensor fusion operation mode. You can use a time processor.to reduce the data rate at the firmware level. https://mbientlab.com/androiddocs/2/data_processor.html#time
-
No, the algorithm only reports roll between [-90, 90]
-
Averaging is not supported on sensor fusion data though you can use a data limiter. https://mbientlab.com/androiddocs//3/data_route.html#time

what firmware version is your board running?
-
The root cause is mostly like that the connection was closed while commands were still being issued to the board which disturbed the internal BluetoothGatt state. The disconnectAsync from the Debug module commands the board to close the connection …

What is the output of params.hasExtra(EXTRA_BT_DEVICE) ?
-
Yes, that is the same value as battery charge from the settings module.
-
You last said you were going to try with another device. What devices did you try and did it make any difference?

Reworking the OnClickListener to this code chunk fixes the issue on my Nexus 6.disconnect.setOnClickListener(v -> { ledModule.stop(true); gyroModule.stop(); gyroModule.angularVelocity().stop(); accelModule.stop(); acc…

What is the value of SCAN_INTERVAL? Furthermore, is the board simply losing connection or resetting? I'm not exactly sure what the natural frequency of the boards are but I doubt they are bring disturbed by a knock.

Check out this demo project on our GitHub page: https://github.com/mbientlab/MetaWear-Tutorial-Android/tree/master/multimw Thanks for the heads up on that page; we'll look into getting it resolved soon.
-
You can check from the app settings menu. I think the exact menu location differs among Android releases so you'll have to look it up for your specific android OS. Hrm, the issue you have could be related to the DFU library the MetaWear app is us…
-
For the specific magnetometer on the boards (BMM150), field strength along the xy axes is measured with different sensing elements than the z-axis (FlipCore vs. Hall plate), and they have different ranges. This might explain why the z-axis is behav…

Can you try the firmware update with an iOS device? Also which version of the Android app are you using?
-
I've never see that behavior before. What do you mean by "faster movements" and do you see this same behavior when using the Android or iOS apps?
-
This is explained in the documentation. Please read through the docs first. https://mbientlab.com/cppdocs/0.7.0/accelerometer.html#high-frequency-stream
-
You need to enable high frequency streaming to stream from multiple devices. See my post from your other thread.http://community.mbientlab.com/discussion/comment/4169/#Comment_4169
-
When you were going through the tutorial, did you successfully complete a download with the boards? If not, initiate a download again with the capture screen.
-
High frequency streaming is only available on firmware v1.2.3 and later; update your board's firmware with an Android or iOS device. Furthermore, pymetawear is a community provided library that layers its own API over the the python wrappers. Que…
-
Can you clarify what you mean by saying "not getting result"? Are you receiving invalid values or not receiving any values? What value is the GPIO_PIN variable set to? Documentation for API v2 is still on the website. https://mbientlab.com/andr…

Can you post the full python code you are using along with the firmware revision that your board is currently running?

Can you post the full python code you are currently running along with the firmware revision the boards are currently running?

Rreduce the max connection interval to 7.5ms. http://community.mbientlab.com/discussion/comment/3825/#Comment_3825
-
Can you provide some data from the 3 devices showing the discrepency?
-
* What Android device and OS are you using? * What is the status code returned to the failure callback? Try resetting the BT adapter and turning off the wifi adapter. These types of issues vary from device to device so it's hard to say for sur…
-
Does the same behavior occur if you use the readBatteryLevel function from the MetaWearBoard class?
-
Can you share your project? I would like to see if i am getting the same behavior on my android devices. Also, do you see the same issues if you put your code into the starter app template?
-
Can you post the data that you are receiving from the two boards along with the code you are using to configure and use the sensor fusion algorithm?
