NRF5340 how to add timesync over BLE NUS

[kyozc]

Hi Nordic:

we want to add timesync function on nrf5340 ble nus.(1central + 16peripherals, 0.1ms precision)

Such as:  

https://github.com/nordic-auko/nRF5-ble-timesync-demo

it‘s based on NRF5 SDK which is not support by nrf5340.

Is there any timesync samples for nrf connect sdk?

Or how can we start?

Thanks

I would have looked into the periodic advertising that is supported in nRF Connect SDK:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/bluetooth/periodic_adv/README.html 

I don't have any data on the accuracy.
