tdoa3 random send, packet will conflict, PTP(Precision Time Protocol) can solve it

hi,

tdoa3 random send, packet will conflict,I think that PTP(Precision Time Protocol) can solve it.
PTP can sync all anchor time, then every anchor run tdma mechanism to avoid collision。

Re: don't read anchors position

I recheck the issue, find that when click the button, the crazyflie's dwm1000deck tx led don't blink, so read anchor's position infomation, don't get it from the anchor board.
