add more anchors, more group

[justinleeyang]

hi, all:

about tdoa mode, the current anchor address 1~7, named as group 1, if we have two zone nearly, add anchor 8~F, named as group2,
group1 maybe affect the 2, how to avoid the interfere? if more groups, how to do ?

Hi,

If you want to have nearby system working independently you need to have them on different channel and/or preamble settings.

hi, arnaud:

if crazyflie2 must receive the two groups ? different channel and /or preamble settings only receive a group.

crazyflie2 try swith to different settings? or other.

If you are in TWR, Crazyflie can switch channel and preamble when talking to the anchor, this would be one good way to improve the TDMA performances. If in TDoA mode though it is much mode difficult since you can only listen to one preamble/channel at one time.
