Date-Time with IPv6

[anicare-tero]

Hi,

OS: Windows 10
Editor: SEGGER Embedded Studio for ARM (Nordic Edition) V5.10d (64-bit)
nrfjprog version: 10.12.1
JLinkARM.dll version: 6.88a
nRF Connect SDK version: 1.4.2
nRF9160 modem firmware version: 1.2.3

I have enabled IPv6 in my firmware and also APN is set to use IPv6. That's making the Date-Time library not working when getting time from NTP servers. The getaddrinfo() is failing there.

Is there any existing way to make the Date-Time library work with IPv6?

Regards,
Tero

I did these changes to make it work temporarily:

nrf/lib/date_time/Kconfig

config DATE_TIME_IPV6
	bool "Use IPv6"
	default n

nrf/lib/date_time/date_time.c

	hints.ai_family = AF_INET;    // REPLACED THIS WITH BELOW

	if (IS_ENABLED(CONFIG_DATE_TIME_IPV6)) {
		hints.ai_family = AF_INET6;
	} else {
		hints.ai_family = AF_INET;
	}

And then enabled that IPv6 for Date-Time library with CONFIG_DATE_TIME_IPV6=y in application.

Hi,

As you have already found, the date_time library is only requesting IPv4 addresses.

Would you be interested in opening a PR, so other users could benefit from this as well?

Best regards,

Do you mean pull request with PR, or what?

Yes, I mean a pull request.

Okay, I will do that.
