@FoolishFrost said: Simple. I never found a way to remove routes. Even the samples I found have addition of null routes. addRoute does not remove routes, the documentation clearly states what it does. https://github.com/mbientlab/MetaW…

* Why are you continually adding routes instead of removing them? * What behaves differently in your code between the first run and subsequent runs? * Same as in the other thread, isolate your code into a self contained static function that re…

* Does this .net core tutorial work for you? https://mbientlab.com/tutorials/WCS.html#stream-multiple-accelerometers * What environment are you running your code in? * Your code snippet involves a lot of other class variables. Isolate your c…

You're just missing some imports. The IDE will provide suggestions and insert the appropriate import statements for you.

@R0b0t1c5 said: My question is regarding the ordering of the code. From looking at the documentation, I need to initialize the board, enable the desired sensor, set the configurations? Then do I need to subscribe to the datasignal for streaming? …
-
You'll probably want to set an initial reference point then compute the Euler angles as offsets from that reference point.
-
In your picture, linear acceleration should be non-zero at some point because there is translational motion. Post the data you measured from your experiment? Does it match what you expected? If not, what is the expected output?

@Force said: What kind of filters, other than a high pass filter, would be suitable for dealing with drift when integrating? Dunno, that's what sensor fusion is for.

@abcd said: * how can i test the macro is working after FW reset beside using ResetAsync? when i will do "Hard restart" the macro will still be there? That is how to you test the macro. …
-
https://mbientlab.com/tutorials/Orientation.html?highlight=orientation I'm not sure exactly what you are asking. Just move the board yourself in each direction and see which axis responds according.
-
@Force said: Just for clarification, both the high pass filter and averager are applied to the raw acceleration values? Yes Also, what's a best practice for dealing with drift when integrating? There will always be drift wit…

This is explained in the developer documentation. https://mbientlab.com/cppdocs/latest/index.html

* What platform are you using metabase on? * what are the specs for your boards? * What do you mean by "fails to return the accelerometer, duplicate 4 times each files (taking an infinite time)"? Provide some examples
-
@nekos said: So corrected acceleration is linear motion + gravity. Yes, that and more. The 2nd sentence if the previous section explains this. I have one more question. Is there any documentation or example for BMI160 step counter …

@abcd said: Hi Eric, 1. I re-wrote the code (see below) and it seems to give me the new name after calling ResetAsync. I don't see any call to ResetAsync in your posted code. However, when i reset from MetaBase android app, the…

No, metabase does not support persistent configurations.

Did you follow the installation instructions? https://github.com/mbientlab/Warble.NET/blob/master/README.md#install
-
Follow the example code for erasing macros: https://mbientlab.com/csdocs/0/macro.html#erasing-macros I'm not sure what you mean by "response time" How are you resetting the board?
-
* Where are you getting horizontal acceleration? * Your accelerometer data is pretty noisy, you'll want to filter / smooth out the data before consuming it. * The links I posted in a previous thread might be of some help

@panjar said: I'm having the same issue: python led.py "CA:0A:65:86:22:1B" error 1561471015.358345: Error on line: 296 (src/blestatemachine.cc): Operation now in progress Traceback (most recent call last): File "led.py", line 11…

Post your data. What do you expect the values to be, what are the values you are seeing?
-
@Jodli said: Hello, I am sorry again. We realised that this firmwarebug causes a lot more problems for us than we initially anticipated. Has there been any progress? Yes, our firmware dev published a release candidate. Barring …
-
Sensors are not perfect and always have some margin of error in their values.
-
This is set by the sensor.
-
Calibration only needs to be done if you are using sensor fusion.

@Oldrich said: I could not find any duration limit in the documentation, so my question is whether there is such limit and/or it is a bug and what would be fast fix to this? Yes, there is a limit of 430s.
