about the NODE_END_SLOT_ID of twr_tag_nranges_tdma

[ihuajiu]

I would like to test the TDOA application, in the process of using mynewt-dw1000-apps\apps\twr_tag_nranges_tdma example, the configuration of tag at compile time is as follows:
Newt target amend tag syscfg=NRNG_NNODES=16:NRNG_NFRAMES=32:NODE_START_SLOT_ID=0:NODE_END_SLOT_ID=8
I have 4 nodes now, I will set NRNG_NNODES=4:NRNG_NFRAMES=8, NODE_END_SLOT_ID should I set it to 4?

RNG has 7 data and tdoa has 7 data. When set to 4, RNG only has 4 data sets. Is there any difference?

Looking forward to your reply.

I have a project that needs to use tdoa-related applications. It needs time synchronization, TDOA ranging, wireless communication. What test cases can be used to achieve these functions?

@ihuajiu,
The mynewt-dw1000-apps\apps\twr_tag(node)_nranges_tdma is the closest fit to your requirements.

Hi Paul,
mynewt-dw1000-apps\apps\twr_tag(node)_nranges_tdma is still two way ranging, right? It's not TDOA ranging.

Hi Feng,

twr_tag(node)_nranges_tdma is still slotted TWR, however, with WCS enabled you can also do Reverse-TDOA with the same examples. With WCS enabled all timestamps are converted to the clock master reference frame.

Hello,
@ihuajiu since you have already run this nranges example, I hope you can help me in some way.
Kindly check this thread. Hope to get your response
