WILINK8-GNSS-DRIVER: Time Sync feature with Wilink8 with beaglebone green wireless (BBGW)

Part Number: WILINK8-GNSS-DRIVER

Hi all

I'm about to use wilink8 module for purpose of sync, my project is to sync between multiple nodes within range of microseconds, I want these nodes to share the same timestamp in range of microsecond, as this TI Application report ( https://www.ti.com/lit/an/swaa162a/swaa162a.pdf?ts=1705670546575&ref_url=https%253A%252F%252Fwww.google.com%252F ) states that a sync over WLAN can be achieved in range of 20 us. I'm about to adopt this solution using beaglebone green wireless that is based on ARM A8 and integrate a Wilink 8 module that all the hardware required as the TI application report mentioned. I plan to use one board (BBGW) as AP (access point ) and the other one as station.
my question is do I need an internet access to setup the NTP on both sides the station and AP as I read in a previous ticket (wl1837 clock sync problem - Wi-Fi forum - Wi-Fi - TI E2E support forums) that the NTP is used to make the sync happen, or I can use the local time of that host (AP) without any need of internet access. 
anther question is how to get started with this wilink8 module with the BBGW to achive this feature of time sync ?

thanks

    Hi Ahmed,

    It depends what you are trying to do. You can use the BBGW as the NTP server but you will have to spend the effort to set it up . Instead, you can connect internet access and have it available for you much faster.

    We don't have a specific guide for the BBGW for these purposes.
