Hi,

Sorry for answering late...

I have set CONFIG_NEWLIB_LIBC=n and since then I can see my float values.

Thank you so much.

What do you mean by float support?

Not sure if you meant this:
https://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_NEWLIB_LIBC_FLOAT_PRINTF.html

I have these in my project:
CONFIG_NEWLIB_LIBC=y
CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y

Thank you, it worked on the latest branch.

Do you know by any chance how to enable float support there?

Best Regards.

Hello,

After updating I can not see my float values when I make a printf(). Besides, the float values that I upload to my server are not visible, it is like floats do not exist.

Which is the solution to this problem?

Best regards,

Ander.

It's not necessary, I have managed to make it run using the latest master branch, but not with 1.2.0. Maybe a Nordic engineer can explain why.

Thanks for your help.

I'll do it on Monday.

Not yet, I could try it as soon as possible and let you know the results.

I'm using the latest master branch of nRF Connect SDK and I have a 1.1.1 modem firmware on nRF9160 DK.

UPDATE: Yes, it does work for me. I let the program run about 10 times and had no problems with it.

Hi,

You are right, I didn't realize that I init more than one the LTE Link Control. Unfortunately, that didn't solve the problem, and after the first cycle it gets stuck at connect() function forever.

Did you manage to get work my project after making the changes you mentioned? If so, which version of NCS tag and modem firmware are you using?

I am really confused why such a simple project works in NCS tag 0.4.0 and not in 1.2.0.

Thanks for your help.

Oh, you are initializing the LTE Link Control more than one time and that might cause some problems.

Do the modem configuring and connecting some way like this:

static void modem_configure(void)
{
	if (IS_ENABLED(CONFIG_LTE_AUTO_INIT_AND_CONNECT)) {
		/* Do nothing, modem is already turned on and connected. */
	} else {

		int err;

		printk("Initializing LTE Link Control...\n");
		err = lte_lc_init();
		__ASSERT(err == 0, "LTE Link Control could not be initialized.");
		printk("LTE Link Control initialized.\n");

	}
}

int main(void)
{

    int err;

    modem_configure();
	
	while (1) {
        if ((err = lte_lc_connect() )){

		    printk( "Failure to connect to LTE network: %d\n", err );
	    }
	    else{

		    printk("\nConnected to LTE network.\n");
	    }
        k_sleep(2000);
        app_http_start();
        if ((err = lte_lc_offline() )){

		    printk( "Failure turning off Modem: %d\n", err );
	    }
	    else{

		    printk("\nModem turned off.\n");
	    }
        k_sleep(120000);
	}
}

Please let me know how this works for you.

Hi;

I have modified my project to make it as simple as possible. The first cycle it runs fine, but then it gets stuck in connect() function.

Any idea or suggestion is welcomed.

Thanks.

Hi:

I am not getting any error code. How can I share my full project? I don't want to make it public.

Best regards.

Hello isurki,

Are you getting any output with error codes? Are you able to provide your full project?

Kind regards,
Øyvind

Hi ziirou;

I think my problem is caused by something else. I think I am closing the socket as it should be:

    CLEAR(recv_buf);
    printk("\n\rFinished. Closing socket.");
clean_up:
    freeaddrinfo(res);
    err = close(client_fd); 

Thanks for your answer!

Hi isurki,

I had almost the similar problem earlier and it turned out that I was closing the socket at wrong way.

Have you checked the samples below?

https://github.com/Rallare/fw-nrfconnect-nrf/tree/nrf9160_samples/samples/nrf9160/http

https://github.com/Rallare/fw-nrfconnect-nrf/tree/nrf9160_samples/samples/nrf9160/https_simple

https://github.com/NordicPlayground/fw-nrfconnect-nrf/tree/master/samples/nrf9160/https_client

I got a lot of help from those samples.

Hello;

I have updated to NCS tag v1.2.0 and modem FW to 1.1.1. I have made some little changes in my project (#include paths) and these are the results:

First HTTP request try works fine. Then, I turn off the LTE connection(lte_lc_offline()). After 3 minutes I establish LTE connection again and the HTTP request gets stuck forever at:

err = connect(client_fd, (struct sockaddr *)res->ai_addr,sizeof(struct sockaddr_in));

One more strange thing I have noticed is that I can not see the print float values in the console. I have found some solutions, but I am not using SEGGER and I flash the NRF manually.

Your help is highly appreciated.

Kind regards.

Hello,

NCS tag v0.4.0 is outdated. I encourage you to update your project to tag v1.2.0. Also, I encourage you to update your modem FW to the latest (v1.1.1), which can be downloaded from here. Both modem version and latest NCS include several bug fixes.

Kind regards,
Øyvind
