Hi Kaka,

There is an NTP example for the CC3100 found at: processors.wiki.ti.com/.../CC3100_Get_Time_Application

Please use the Gen1 to Gen2 Migration guide to migrate the code to the CC3120 found at: dev.ti.com/.../SimpleLink_Gen1_to_Gen2_SDK_Migration_Guide.html

Sincerely,
Bryan Kahler

Hi Bryan,

Thank you for your response.
I have already known this sample code. If SNTP used, they thought that it is not think the delay between AP and STA. So, it is difficult to use in order to meet their required time accuracy.

I also find the following standard. Would you please answer for my other post?
