very appreciate 
for your answer ,
regarding about what you ask about my mean of "Simultaneous " ,–> so i will describe to you about my question that i already posted in my thread above about my mean of "SIMULTANEOUS " to be more clearer
note → i already tested ranging 1 to 1 → 1:1 about 1 of DWM3000EVB range to 1 of iPhone 11 → WITH DWM3000EVB MOUNT ON nRF52840DK (nordic board) *. and after ranging 1:1. the result of ranging has been displayed on jLinkRttViewer , eg. → as the some of images below
above is image of ranging DWM3000EVB to iPhone11
. -----> nRF52840DK
—> jLinkRttViewer monitoring dashboard
question number 1.) my mean of " simultaneous" is as the attach image below → (( 1 of DWM3000EVB that mount on 1 of nRF52840DK )) simultaneously range to 2 or more than 2 iPhones 11 then display the ranging result to the **jLinkrttViewer ** monitoring dashboard
above image is the single result of ranging 1:1 → between 1 of DWM3000EVB to 1 of iPhone11 as the displaying of 1 object result (TWR–> “a16”:"0x4ae2 ") that display on jLinkrttViewer monitoring dashboard as the **white highlight in the image above
** regarding to this image above with my description of my question 1. ) , —> *once 1 of DWM3000EVB mount on nRF52840DK then will it be possible to simultaneously range to 2 or more than 2 iPhone 11 then display the 2 simultaneous ranging 's result to the jLinkrttViewer ?? 
yes or no ??
question number 2 .) regarding to the question from the thread of 1 guy (Matthew ), i am interested what matthew posted his thread in image below
In case of scenario as attach figure above–> if there are several (5) of u1 equipped iPhone has been grouped together , 5 of DWM3000EVB has been located around 5 iPhones as figure above
→ 5 of DWM3000EVB simultaneously start interacting / ranging to the specific red color iPhone number 1 as the image above , **but only Simultaneous interacting / ranging to only specific single / one red iPhone no.1 , right 
so i want to send the results from 5 of DWM3000EVB as the figure above to jLinkRttViewer , will the jLinkRttViewer be possible to display 5 results of ranging between 5 DWM3000EVB to 1 of specific red iPhone number 1 ??
Question number 3. ) → regarding to my Question number 2.) above → there are still remain of 4 iPhones ( no. 2 - no.5 ) Need to be interaction / ranging to 5 DWM3000EVB , how to do ? because right now during DWM3000EVB simultaneously start interacting / ranging to the specific red color iPhone number 1 , as the same time , the rest of 4 iPhone (no.2 - no.5 ) need to be interacting / ranging to the same 5 of DWM3000EVB which have been interacting / ranging to red color iPhone no.1 simultaneously ,too , so how the same group of 5 of DWM3000EVB will be able to interacted or ranged to the each of the rest of 4 iPhones ( no.2 - no.5 ) SIMULTANEOUSLY during have been ranging / interacting to red color iPhones no.1 ??
question number 4.) regarding to apple nearby interaction framework to display 3D AOA as the iPhone 11 SIDE as figure below , you will be able to see **ANGLE OF ELEVATION AND AZIMUTH
however → image above ,currently Decawave/Qorvo has no UWB chip or any chip serie of DWM3000 that can get 3D AOA from Iphone11 then display the result of the 3 angles XYZ to the jLinkRttViewer , am i right ?
question number 5. ) Regarding to the image below from the official apple nearby interaction video wwdc2021 at 19:43 Explore Nearby Interaction with third-party accessories - WWDC21 - Videos - Apple Developer
regarding to the information , apple bought decawave then rename it to Qorvo and Decawave/Qorvo make u1 chip to Apple iphone ,so what i want to ask →
**do you know why the apple u1 chip will be able to simultaneously range to 5 or multiple DWM3000EVB , in contrast , → will single or one DWM3000EVB be possible to range to 2 or more 2 iPhone11 and display the multiple ranging results to jLinkRttViewer simultaneously as the thread that i posted ??
thanks
