Can I put all anchors in the same height?

How to calculate position update rate using TDMA?

Dear all, I was trying to understand the update rate from this comment: The system will run with 2^TDMA_NSLOTS_BITS slots. So to fly between 3 and 4 Crazyflie set TDMA_NSLOTS_BITS=2, up to 8 set TDMA_NSLOTS_BITS=3, etc ..... Each time slot is 4ms long so adding more slot will slow down the ranging r...

Re: Testing different LiPos

Hi guys,

So how long can CF fly with 380mAh or 500mAh battery? Do we need to get a more powerful motors for that?

Thanks!
