Hi @ybppbzm ,
Actually, I’ve confirmed with our engineers that there is no restriction on the range of block duration.
There is no restriction on the range of slot duration or the number of slots in a ranging round as well.
Specifying the range is a mistake, and it will be removed in the next SDK version.
For now, you can tweak the code and remove the condition on those FiRa parameters.
This should work with any value.
However, as I explained above, you need to carefully choose the values of block_duration, slot_duration, and slots_per_ranging_round together to have a valid scheme.
Thanks,
Wassim
