SPWF01SA NTP client

Hi,

Is there a sample implementation of a NTP client to get the time from a timeserver?

I use the SPWF01SA together with a STM32F401.

BR,

Manfred

Hi Manfred,

if SimpleNTP is enough, you can open a simple UDP socket  (AT+S.SOCKON) and write (AT+S.SOCKW) a 48 byte requesto to server. Than expect a 48 byte reply, and read (AT+S.SOCKR) it.

 a simple flow.

Hi Gerardo,

SimpleNTP is accurate enough.

Thanks for your quick answer.
