  in How to set magnometer frequency higher than 30Hz Comment by JanWeber November 2018
• How can be change to forcedMode? According to Bosch is should be possible to get a much higher frequency than 30.

• So, what are you saying? Not possible to get higher Hz than 30? Or?

  in How to set magnometer frequency higher than 30Hz Comment by JanWeber November 2018
• We use the MetaMotionR board

• @Eric said: Which SDK are you using? https://github.com/mbientlab/MetaWear-SDK-iOS-macOS-tvOS.git'

  in How to set magnometer to 25Hz (Metamotion R) Comment by JanWeber July 2018
• Hi Eric - Is this due to the BMI160 or ? Its pretty important for us to get the raw unfiltered G’s and use smoothing in sensor fusion for better angle estimation. Therefore its nice to know if/how it is possible to grab the raw data before smoothing

• Hi Eric I would like to extract both the raw (full bandwith) accelerometer and gyroscope readings and use one of the other filter settings in the sensor fusion (1/2 or 1/4 bandwith).  Currently, when we are extracting the accelerations and gyr…

• Hi Eric &Matt Any idea how to test different filter settings just using stored raw sensor data? Maybe a git library or any other way to feed sensor fusion with raw data and have the possibility to change filter settings?

• Perfect! When is this official?

• @Matt We are looking at drift in pitch. We are using our own iOS app. As I understand, you would make changes to allow for a different filtering on the Acc and Gyr data? This could might work and worth testing. If you need a mail, is jwo@trailsens…

• Hi Matt and Eric, Did you get the chance to have a look at the new data? Feel free to give me a call at +45 20342366 for a talk on the very important subject to us. Thanks

• Hi I have collected some more data to you. This is a ride (still same placement of the sensor on the frame) without the magnometer on a smooth and flat road. Angles looks much more stable then with the magnometer, but is still shows that the pitch…

• Thanks. I still think there is more to it than just the noise. The data send to you is from a ride on a pretty smooth surface, so should bump noise really make sich an impact. I have been working on an own sensor fusion, and its not that easy to get…

• Hi Matt I will collect data for you from good to bad angles. We want to be able to read the bumps of a ride - this is the idea. So placing the sensor on the helmet/body is No option. When I do a simple complimentary filter with HP and LP filter…

• One of my team members made a test today with the sensor. It seems that placing the sensor away from the bikes frame and other parts gives a better result (for example placed on the helmet). He drives an aluminium bike frame. When using the IMUplus …

• It seems random to me. It happend maybe 5-6 times during a ride of 1 hour (of what I noticed). However, it is consistent that the angle is corrected when bringing the bike to a stop.

• Hi Eric and Matt I have placed the sensor the "correct" way, so the axis should fit. I still experience sharp decrease/increase in pitch angles, which are not true.  For this data, I been riding the bike for 2-3 minutes with normal speed (arou…

• By the way; Can the magnometer be disabled in the sensor fusion?

  in Sensor fusion makes lots of noice Comment by JanWeber October 2017
• @Matt Yes, where the “noise” has been the lagres the sensor has been placed on a alu frame. I still experience some issues when the bike has been in speed for some time, and I will try to collect some better data. The sensor is now being placed at …

• Hi Eric. No, I’m positive that this is not the case. I have done several test that works well and as expected, but sometimes it doesn’t work well at all.

• To Eric: This file contains data for a longer bike run and better illustrates that the angle (see the ROLL) changes a lot even though the surface grade is close to 0%. My simple complimentary filter shows an angle varying around 25 degrees, wherea…

• To Eric: - The sensor is placed on the top of the bike frame between the steering and the seat with the bottom pointing up. - The sensor runs in NDoF mode and logs euler angles. No further configuration is done. Its not every time the senso…

• The sensor runs in NDoF mode and returns euler angles pitch, yaw and roll

• Hi Eric. The sensor is placed at the front fork on the bike. We are reading pitch, yaw and roll. Im not sure how the fusion algorithm is configured (maybe just using the default - I will check). The problem is that the horizontal angle of the bike p…
