Thanks for your suggestion. was not aware that zephyr had sntp. That may well be a better solution. We have two applications with very different time constraints--none of which are at the ns. level. One app needs roughly 10 ms. resolution and a second would like to see something on the order of 50 - 100 usec.
BTW, are there any "standard" solutions for time sync (at any resolution) for BLE or bluetooth 5?
