"supl_session.h" file missing

RE: "supl_session.h" file missing

Balamurugan — Sat, 15 Feb 2020 06:45:51 GMT

Hi,

I wrote TCP socket program inside the GPS application where it starts the supl and noticed that socket is not behaving properly, couple of write works and read not works. then add "AT+CFUN=4" offline just before the supl and then activated the LTE and found that socket is works fine and supl also works fine.

then tried GPS stop before supl and resumed after supl and all works fine. looks like GPS active and LTE active causing socket issue.

Below is the final code changes which works fine for me.

#ifdef CONFIG_SUPL_CLIENT_LIB
printk("\033[1;1H");
printk("\033[2J");
printk("New AGPS data requested, contacting SUPL server, flags %d\n",
gps_data->agps.data_flags);
nrf_setsockopt(gnss_fd,
NRF_SOL_GNSS,
NRF_SO_GNSS_STOP,
NULL,
0);
activate_lte(true);
printk("Established LTE link\n");
k_sleep(K_MSEC(3000));
if (open_supl_socket() == 0) {
printf("Starting SUPL session\n");
supl_session(&gps_data->agps);
printk("Done\n");
close_supl_socket();
}
activate_lte(false);
k_sleep(K_MSEC(2000));

nrf_gnss_delete_mask_t delete_mask = 0;
retval = nrf_setsockopt(gnss_fd,
NRF_SOL_GNSS,
NRF_SO_GNSS_START,
&delete_mask,
sizeof(delete_mask));

if (retval != 0)
{
printk("Failed to start GPS\n");
return -1;
}

#endif

After adding highlighted code its working fine. but im not sue about the root cause.

I have attached the working log.

Please investigate and share the solution.

Thanks,
Bala

Hi Bala,
Please make sure you are using the latest modem firmware version.
You may also need to add these two configs in your prj.conf:

CONFIG_LTE_NETWORK_MODE_NBIOT_GPS=y
CONFIG_LTE_LEGACY_PCO_MODE=y

Best regards,

Martin L.

Hi,

Have you checked this?
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/include/supl_os_client.html

The SUPL client library is released under a different license than the nRF Connect SDK. Therefore, you must download and install it separately to be able to use this module. Before you download the library, read through the license on the webpage. You must accept the license before you can download the library.

You can download the SUPL client library from the nRF9160 DK product page.

Download the nRF9160 SiP SUPL Client library zip file and extract it into the nrf/ext/lib/bin/supl/ folder. Make sure to maintain the folder structure that is used in the zip file.

That zip file doesn't exist on DK downloads so I think you have to contact your Regional Sales Manager if you want the library.

Regards,
Tero
