Hi,
Im using nrf9160 based custom board, nrf sdk 1.5.1.
I want to get the time from NTP servers, for that i connected to CATM1 n/w, connected to NTP server using UDP Protocol, but im not understanding what is the request i should make for NTP server to get present EPOCH,
Please share any example if available.
i have tried sntp_client example (zephyr/samples/net/sockets/sntp_client) but when i run my code its directly going into fault_s.S after spm_jump() function.
Best Regards
Rajender
Hi,
Now i can get the time from ntp server (time1.google.com) using sntp, but i want to get the time from at%xtime=1 also,
I am sending this %xtime command after network connected and got ip address, but still im getting nothing but "OK" as a response, what would be the reason for this?
Best Regards
Rajender

I'm glad to hear that you got ntp running.
The %XTIME enables a notification, so it is important that you enable this notification early in the process.
This can require that you enable the notification prior to connecting to the modem, ie. by setting CONFIG_LTE_AUTO_INIT_AND_CONNECT=n in your prj.conf and connecting to the network in main, something similar to this:
https://github.com/nrfconnect/sdk-nrf/blob/v1.7.0/samples/nrf9160/mqtt_simple/src/main.c#L506-L545
Kind regards,

Hi,
I was connecting the network through main only, and please take a look at my network connecting function.

this is my prj file, here i already done this, CONFIG_LTE_AUTO_INIT_AND_CONNECT=n.

The network will provide the time using XTIME. Does your SDR support this?
Kind regards,

How can i know that?
I tried sending at%xtime=1, its just sending ok, nothing more than that, so how can i make sure that my SDR supports this?
