Hi I have an interesting question. I need to know if I can use 8 anchors and 1 tag. And 8 because I need to test it in a big environment. So as I have read in resources that we can actually use 4 anchor ids maximum for a dw1000. Therefore if my tag moves away from the four anchors and will reach to different set of 4 anchors will the tag detect it and get distance info. And if yes then can it also use two anchors from the prev set 4 and 2 anchors from the coming set to communicate for distance. So that I can get continuous distance reading.
This is an amazing result with the ESP32+DW1000. I'm currently working on a project with these ESP32+DW1000 modules and I"m having trouble when I want to connect a second TAG, have you by any chance tried to connect a second TAG? Or do you know perhaps what would do the trick? I've been trying to set a scheduler but the whole protocol seems to bug when pausing and resuming the tags.
So far my project has been working with one DW1000 Tag and several DW1000 Anchors. As far as I know, in order to connect multiple tags to one anchor, it seems that you need to use another library. Currently, arduino-dw1000 has a problem connecting multiple tags.
when I use 4 anchors and 1 tag, the anchors signal will interfere with each other, that lead to the distance of anchor to tag will change, could you tell how to solve the interfere ? Thank you.
How can anchor and tag be changed? The only data that can be obtained from the tag is the distance data of multiple anchors. I don't know much about this because I didn't have any problems with signal interference.
@@ThatProject for example, I turn on a TAG A and a ANCHOR A, the distance is 1m, when I turn on a ANCHOR B, the distance of TAG A to ANCHOR A is detcted 1.2m, and the distance of TAG A to ANCHOR B is 1m but it is dected 0.8m, turn on more ANCHOR, those distance will be more affected. Have you not encountered such a problem? thank you~
@@ThatProject oh my god,,,,I also use that mode, have you set " DW1000.setAntennaDelay(Adelay);" for anchor? the delay value , I set for four anchor with it's own value, but it can not solve above problem. And can you tell me the infomation of adapter board of DW1000 on your project? thank you.
I would say yes or no. DWM1000(BU01) can recognize one or more Tags in Anchor, but the library currently in use does not support this. For this, the library needs to be updated, but maintenance is not taking place. That's why I'm looking for another UWB chip.
@@ThatProject Wow, could you roughly describe how the position estimation was done? When four distances from the known position anchors are provided? How exactly did you improve the accuracy like in the video?
@@joo9421 Isn't the most important thing calibration? As I mentioned in the video, there is a difference between the distance calculated by ToF and the actual measured distance. Reducing this gap helps to increase accuracy. Also, using a filter (like the Kalman filter) rather than directly using the raw values seems to enable more accurate positioning.

code for project?
That is very cool. So many possibilities come to mind. Would like to see this with multiple objects such as robot cars and drones interacting.
That's pretty good work there! Can't wait to see what you do next!
yes, you've just given me a lead on a project I've been thinking about thank you and good work
Brilliant work! Please continue ... Would love to see your idea for the higher sample rate tested.
The project is really intresting.
And great to see my measuring tool helping you to achieve you goal.
And thank you the recommendation.
impressed
real XYZ indoor Position
No.1
Thank you! this is exactly what i'm looking for!
this is amazing.
Very interested ~!! I just think uwb module has limit on calculating distance but you did it !!
That is very cool.

@@kamli2661 That's weird. In this project I tested with 4 Anchor devices and I didn't have that issue. FYI I set it to MODE_LONGDATA_RANGE_LOWPOWER.

@@kamli2661 I did not use the setAntennaDelay function, and here I used a custom board based on DW1000 and ESP32.
I see possibilities with this system...is this merged with the IMU data?🌚
Attaching an IMU sensor to a tag device is not difficult. I've already done this in a previous project. th-cam.com/video/fPuxcjHsfpc/w-d-xo.html
Was trilateration used for this? If so how does that work with 4 anchors?
You're right and I used 4 anchors and 1 tag for this project.
@@ThatProject what if there is no exact intersection point?
Can it be done with less than 4 anchors?
I attempted triangulation using three anchors, but it was very difficult and ultimately failed because I did not get the desired results. Any ideas?
can i use more than 1 tag?
I would say yes or no. DWM1000(BU01) can recognize one or more Tags in Anchor, but the library currently in use does not support this. For this, the library needs to be updated, but maintenance is not taking place. That's why I'm looking for another UWB chip.
You don't have this project in your github.
Since this project was created for a different purpose, the source code is not opened.
