Hello all,
I'm trying to conduct a wifi round-trip time(RTT) research using nest wifi. I think the nest wifi point also supports RTT FTM, right? My question is, if I have a router and multiple points connected, when I request RTT from the phone, will the RTT be the travel time between the phone and the router or between the phone and the nearest wifi point?
Thank you for your help in advance,
Allen

Hello @Allen997
According to this page: https://developer.android.com/guide/topics/connectivity/wifi-rtt#supported-aps both the Nest WiFi Router and Nest WiFi Point support 802.11mc RTT. From a quick look at the relevant APIs, it looks like you do a scan first to get a list of access point MAC addresses, use those to build a ranging request, and then initiate the ranging measurement. The results will include all of the measured ranges from the access points (and in this context, the Nest WiFi Router and Nest WiFi Point units are all "access points"). If you want to know which access point is the closest, you'd sort those results by the RTT to find the shortest one.

I know it's been a while since you posted, but I just wanted to jump in real fast to see if you saw MichaelP's reply and to see if you still needed some help on this or if you were able to get it sorted out.

Hi, everyone.
As we haven't had any activity here recently I'm going to go ahead and close the thread. If you have more to add, feel free to start a new discussion.
Thanks
