Yes, this looks right.
-
Keep us updated!
-
You definitely have to code that yourself because there are many different options for sensor fusion. We have pre-made examples for you in a number of languages: www.mbientlab.com/tutorials.

The issue is just with the MetaBase App. You can retrieve that data with our downloading APIs.

Hey Pete, When we did our ML/AI worked we use a lot of Javascript and Python AI/ML libraries and everything we did was on an Intel Nuc running Linux (Ubuntu 16/18 is nice). We also used expensive BLE dongles.

Not enough information. Will delete this post if no debug information is provided.
-
Hey @bhargav, I might have been wrong, euler might work for 180 degrees but quaternion would be the option for 360.
-
Save the values into a variable and then use whatever development language you are in to manipulate the values. This requires coding/development skills.
-
Please see our tutorials and watch the videos: https://mbientlab.com/tutorials/MetaBaseApp.html You can then select quaternions or euler as the output. If you want to have a very specific setting for the output of the sensor fusion, you need to us…

No enough information to help unfortunately. Please see our "how to post".

You cannot touch the sampling rates for sensor fusion. SAMPLING RATES FOR THE SENSORS ARE FIXED FOR SENSOR FUSION. ALL SENSOR FUSION OUTPUTS ARE 100HZ AS PER BOSCH. If you want to downsample, you have to post-process using our tools (such as a cou…

You can check the sensor calibration portion of our tutorial. These values are specific to BOSCH and their calibration (which is something we simply open to you). You should checkout their documentation: https://www.bosch-sensortec.com/products/smar…

Yes you can do that.
-
did you actually write mac_id?
-
The MMR already does that for you as part of sensor fusion.
-
I2C is fine, just make sure the sensors works on 3V

-
You cannot low pass a fused output. Low pass first and then fuse.
-
Yes, it is ok if its one axis as long as you don't get gimbal lock (one of the other axis is the same).
-
Please install everything (don't leave out utils) and send screenshots
-
Keep us updated. Also make sure Bluetooth is on and functioning in the settings. Also some Windows machines come with Bluetooth but not BLE (Bluetooth Low Energy available in Bluetooth 4.2 or newer). You need to make sure your machine is BLE comp…
-
There is a section about this in our tutorials. You need to set up bluetooth in your virtual OS. You can google-fu this.
-
Did you install the drivers as per our tutorials?
-
Yes, our APIs allow you to change the sampling frequency, just follow the tutorials.
-
Please see the fuser in our tutorials. This is what it does.
-
If you get a segmentation fault, it means the API calls are not being used correctly. It is a code error. For example you are sending an INT to a callback that expects an POINTER type.
-
You would need to quantify this issue and send us replicable steps to look into it. Currently all users are reporting Swift > Python. That being said, maybe your Linux based dongle is simply better than the default Bluetooth antenna on your iOS d…
-
@maj, Make sure to lookout for Windows updates, they know BLE is an issue and should have addressed it by now. Update your system and see how it goes. I don't have any suggestions for specific dongles but our most reliable systems we put out in th…

Only 1 sensor fusion output is allowed at a time. The data fuser does NOT work on sensor fusion signals.
