Android WiFi Device-to-AP Round-Trip-Time (RTT) -


with android api-level 21, respectively 23 methods measure wifi roundtrip time (rtt) added sdk:

but not find information how use api measure rtt.

the relevant class rttmanager still marked system api.

is there way perform device-to-ap rtt measurement?

i wrote small libary wrap hidden api calls within compat class:

android rttmanagercompat

the lib makes use of java reflection access api , seems work.

update:

  • the app has installed in system/priv-app/ folder
  • therefore phone needs rooted.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
