Hi Jean Marc and List,<br><br>
So I have started finally fiddling around with Ultra-wideband mode.<br>
It appears to be very similar in operation to Wide mode, except that<br>
when peering into the packet structure it looks like (and these are<br>
kind of questions as much as statements here):<br><br>
1. update rate 0 is not used in UWB- only 1-4?<br>
2. The total bits used for each UWB update rate seem to be as
follows:<br><br>
<font face="Arial, Helvetica">0:36 bits (a guess)<br>
1:72 bits<br>
2:148 bits<br>
3:224 bits<br>
4:384 bits<br><br>
</font>I found one case where these numbers didn't work (for update rate
1),<br>
where it appeared to be maybe 68 bits instead of 72- is this a
variable<br>
number? If it is how do I check for the variation?<br><br>
Which leads to my follow up- it was hard for me to determine why in <br>
some cases UWB was 36 bits per packet more and other cases only <br>
32 than WB mode. I couldn't find anything in the code that could
easily <br>
account for the difference. The only thing I could find didn't
account for <br>
all 32/36 bits. Any pointers appreciated...<br><br>
Thanks!<br><br>
Tom<br><br>
