Hi Laura, Thanks for the update. But even setting the tx mode higher the issue still exists. Previously, before increasing the TX, the sensor wouldn't start while placed at a specific orientation. But now, while moving the sensors around, it sto…

Hi Laura, I am facing the same issue... (libmetawear.mbl_mw_settings_set_tx_power(self.device.board,4)) any plans for new firmware release?
-
I removed the lines. Yes, some noise is fine..but the filtered data produces random values. for instance if you notice the quaternion z values are very noisy(second graph) even when the sensor is placed on the table. shouldn't be similar to the firs…

Hey Laura, thanks Not sure what was the issue. Based on the examples i found in the git, i manged to make it work. I was doing as an experiment to test how these filters work and I noticed the following outputs. I plotted the values and this w…

Hi, I just gave it a try. I set the parameter libmetawear.mbl_mw_settings_set_tx_power(self.device.board,4). It seems to be working now when I tried for a couple of times. I will update if I noticed the same issues again later today

Hi Laura, I don't recall having this problem couple of months back. And I guess during which I had 1.5.0 firmware. I had recently updated the firmware in all my sensors. And noticed this was happening. Thanks

Is there a way to fix the *** buffer overflow detected ***: python terminated? Have issues while connecting to multiple sensors metawear sensors? example of the code used: from future import print_function import sys from mbientlab.metawear i…

Hi Laura, Thanks, I managed to do this. Though its not very accurate, but have figured a way to do real time control in blender

Thanks

@Laura said: I would google white papers on this topic. We are sensors expert. What you do with the data is entirely up to you, we don't do any of the data analysis (thats your job - ) Thanks fair enough.
-
Great. Thanks. Is there any information that you can share it with me regarding this ? Like a pseudocode or something? It would be of great help. Thanks
-
Yes I did by myself. I managed to fix the issue and now I can print the result. So, it gives me the direction and sign along the axis of acceleration. Thanks for your support. Is it possible to estimate the stride length using two MMR sensor pl…

Hi, I kind off fixed the issue for now.

Sure,I looked at the documents and tutorial and tried it myself. And I have an error, argument 3: : expected CFunctionType instance instead of function. I worked on getting a solution online but I am not able to solve this. Can you tell me where I…

I have very minimum experience with programming. So can you give me an example for how to write a call back function for this in Python? mbl_mw_datasignal_subscribe(motion_signal, nullptr, [](void* context, const MblMwData* data) { auto cast…

Do you have something for python?

I have given the code I used for step detector already. def data_handler(self, ctx, data): print("Steps detected") self.samples+= 1 for s in states: libmetawear.mbl_mw_gyro_bmi160_start(s.device.board) libmetawear.mbl…
-
thanks But, the step detector doesn't seem to detect steps. Not sure if its a mistake in the code or with the sensor.
-
Thanks Laura it worked fine. Is it possible to stream the steps in real time? Similarly, I tried the same with the step detector, and it isn't able to detect the steps? for s in states: libmetawear.mbl_mw_gyro_bmi160_start(s.devic…
