case about fun at_monitor_sys_init

[peter.min]

Hi,

1.How can I use this function?

static int at_monitor_sys_init(const struct device *unused)
{
	int err;

	err = nrf_modem_at_notif_handler_set(at_monitor_dispatch);
	if (err) {
		LOG_ERR("Failed to hook the dispatch function, err %d", err);
	}

	return 0;
}

/* Initialize during SYS_INIT */
SYS_INIT(at_monitor_sys_init, APPLICATION, 0);

2.Can you provide a simple example

3.I have the following information, but I still don't know how to use it.

Hi,

What are you trying to do?

As the documentation you linked to and screenshotted says, the at_monitor library is initialized automatically, so there is no need for you to initialize it manually.

To see how you can use the at_monitor library, you can look at the at_monitor sample.

Best regards,

Didrik

HI  Didrik Rokhaug,

I want to use this function on projects where the SDK was in mass production prior to NCS V1.8.0

My customer had to make this compromise because your NCS V1.9.0 was too aggressive and cut the sample asset_tracker

Thank you for all your assistance.
Kind regards,

Like I said, in NCS v1.9.0 you do not need to call it manually. It is called automatically before the application starts.

In older NCS versions, at_monitor_sys_init() is also automatically called at startup, though this can be disabled by setting CONFIG_AT_MONITOR_SYS_INIT=n. If you do that, you can initialize the at_monitor library by calling at_monitor_init() from your application.
