Re: IMU Quaternion 2 values are always 0

Hi! Have you found something about this? This problem still occurs to me, and I need the qw qx qy qz values :-( sad sad

qw qx qy qz vx vy vz ax ay az
0.079 0.000 0.304 0.000 1.994 0.000 1.774 2.697 6.950 -6.423

This is an example of the data I have. qx qz vy are always 0.

Data of device A is not collected when B is occluded (same to B and C, C and D, etc)

This might be something the developer already knows. I am using RX mini as stationary sensors, and track multiple HW sensors. They work fine normally, and let us say that I am tracking 3 HW sensors (HW1, HW2, HW3). When HW1 is occluded perfectly so it loses the line of sight, HW3 still works great, ...

IMU quaternion's accuracy

Is this possible that occlusions may reduce the accuracy of the IMU quaternion data?
I am trying to track the tilt angles of the sensor which travels somewhere line-of-sight is often interrupted.
I am wondering if the occlusion only affects the location.

Re: IMU Quaternion 2 values are always 0

Hey this is what I found from the values printed out. I believe this information can be helpful to solve the issue. LINE1: IMU fusion: Timestamp: 00163591, X=0.000 Y= 0.000 Z=0.000 q=0.485,0.000,0.084,0.000 v=-1.157,-0.001,4.249 a=0.881,-6.342,-6.397 LINE2: Address: 22, X: 4.843, Y: 0.841, Z: -1.157...

Re: IMU Quaternion 2 values are always 0

Thanks for the reply. I changed the setting, and it seems that the problem remains. The attached files are the setting of my mobile beacon. Output mode: IMU fusion data IMU fusion location: enabled IMU fusion quaternion enabled IMU fusion velocity: enabled IMU fusion acceleration: enabled I am not s...

IMU Quaternion 2 values are always 0

I am using HW as a hedgehog, and receive the data from the modem via USB. I have attached my setting and the output. The quaternion data is somehow weird because the second and the forth values are always 0 even when I move it and tilt it. I have tested with another device, and the result is the sam...

Re: How to retrieve IMU data from mobile sensor connected to Raspberry Pi

I have the same issue. I added one more line in python script to print the raw imu data. print ("Hedge {:d}: X: {:d} m, Y: {:d} m, Z: {:d} m, Angle: {:d} at time T: {:.2f}".format(self.position()[0], self.position()[1], self.position()[2], self.position()[3], self.position()[4], self.position()[5]/1...

Re: Points in the Dashboard map not updating

I found that on the new version of Dashboard, I had to change the 'Maximum speed'. It was set as 0, and that was probably why it was not moving.
