What is the different calculation of TdoaV1 and TdoaV2?

Hi everyone, This question's answer is very important for me. Because I'm working on positioning only DWM( not use MPU ) . When I worked on the TdoaV1, I'm create a calculation algorithm with only DWM data. This algortihm take 3 different packet from our Tag and it was starting the calculation the p...

Tdoa Communication Data

Hi , I want to learn that what package is being used for positioning while New LPS system is running. For example ; The master anchor is in communication with which anchors to use and which TdoaDistDiff value is used for positioning. I want to know the values of 'Anchor', 'PreviousAnchor' and 'TdoaD...

Hi everyone, First of all , I am grateful to you for this project. I changed my LPS code TdoaV1 to TdoaV2 . When I examined the Crazflie 2.0 hardwares i saw the MPU-9250 sensor (https://wiki.bitcraze.io/projects:crazyflie2:hardware:specification) . However when i started the change the code , i saw ...

Re: Tdoa positioning is slow

Hi Arnaud, I'm using STM32L433 for my Tag and STM32F103 for my Anchors. By the way, I made some changes in the code to fit for those MCUs. I'm a Software Engineering student I'm working on the Indoor Positioning Systems in my thesis. I wasnt using the MPU sensor but now i have added mpu9255. I just ...

Re: Communication problem Between Anchors and Tag

Hi Arnaud,

I'm using Crazyflie 2.0 but I'm not use the Tdoa version 2.

There is not any sniffer node device . I'm use the 1 Tdoa Tag and 4 Tdoa Anchor.

Thank you ,

Re: Tdoa positioning is slow

Hi Arnaud,

First of all, Thanks for your answer.

I added MPU-9255 Sensor in to My Tag. I want to send data to Kalman Filter in the code. Which format should I send this data to the function ? Is it raw data or another format ?

Best Regards,

Ege

Re: Communication problem Between Anchors and Tag

Hi Arnaud, First of all , thanks for your answer. I know that The Tag is only listening. When I analyze the communication line, I saw that communication is not true for anchors each other. I expected that every anchor communicate each other respectively based on TDMA method. However, my system worki...

Communication problem Between Anchors and Tag

Hi everyone, I have a problem that I hope you will help. I use the TDoA positioning method in the project. When I use the Bitcraze positioning code , I face a problem about communication between devices ( anchor and tag ) . My Tag that I want to track is not correctly communicate with anchors. I exp...
