Digi Connect ME 9210 SNTP timing accuracy

hello all,

I’m using Digi ESP NET+OS and Digi Connect ME 9210. Now I have some questions about the development board and SNTP.

I’m using part of the NET+OS Sample Project - SNTP time sample and want to know:

  1. What’s SNTP’s timing accuracy?
  2. How to set up (or determine) the time synchronization interval? In other words how often synchronize the 9210 itself with the SNTP server?
  3. How to get timestamps with millisecond precision?
  4. Is it able to migrate NTP protocol to this board or do you have some sample projects about NTP?
