MQTT blocks restarting GPS?

[jlienau03]

Hi,

I'm writing a program that swaps between LTE and GPS to send the device's location to AWS over MQTT. I am able to connect to LTE and AWS, then swap to GPS and get a fix, and swap back to LTE. However, when I then try to go back to GPS, I get a bsd recoverable error 3, and it appears I cannot communicate over the GPS socket.

If I have everything EXCEPT connecting to MQTT, I am able to freely swap between LTE and GPS.

I've attached my code below:

called by main():

void test_gps(){

    spoof(false);

    led_setup();
    button_setup();

// Storage
    // Set up certificates before nvs or else permission errors
    provision_certificates();

    nvs_setup();
    printk("\nNVS set up\n");
//---

    k_sleep(1000);

//// MQTT
    int err;
    struct mqtt_client client;
    struct sockaddr_storage broker;
    struct pollfd fds;

    s64_t timer = k_uptime_get();

    begin_lte_only();
    lte_lc_offline();
    modem_configure();
    lte_lc_edrx_req(true);

    client_init(&client, &broker, CONFIG_MQTT_BROKER_HOSTNAME);
    aws_fota_init(&client, CONFIG_APP_VERSION, aws_fota_cb_handler);
    err = mqtt_connect(&client);
    if (err != 0) {
            printk("ERROR: mqtt_connect %d\n", err);
    }
    printk("MQTT Connected");
    fds_init(&client, &fds);
    boot_write_img_confirmed();

Using the debugger, I was able to find that the error occurred after the call to  retval = nrf_setsockopt(gps_socket, NRF_SOL_GNSS, NRF_SO_GNSS_START, NULL, 0);

What's going wrong?

Thanks.

Hi Johnny,

Good news.
A stripped-down and a more user-friendly sample has been made with GPS + LTE.
Please find the sample here:  https://github.com/Rallare/fw-nrfconnect-nrf/tree/nrf9160_samples/samples/nrf9160/udp_gps 
You could either add that sample in your NCS environment or copy the whole repository of "rallare".

(remember to do a 'west update' in the nrf folder so you get the other repositories in the correct state)

If you are only going to copy that sample to your NCS, you need to use the master branch.

cd ncs/nrf
git checkout master
git pull
west update

Best regards,
Martin L.

Hi, Martin. I followed your instruction, but I got this error. Could you give me any advice?

What I did

1. Download the Rallare nrf folder and place it under ncs folder.
2. Run "git checkout master", "git pull", and "west update" under the nrf_rallare folder
3. Try to open the folder => got error

nrf tag: v1.0.0
SES: v4.16

[Martin Lesund]

Hi Yusuke,

If you are using the Rallare fork, and want to use the nrf9160 samples you need to checkout the correct branch.

cd ncs/nrf
git checkout nrf9160_samples
west update

Then you should be able to open and run the samples.

[Alan Hasty]

Hey! - I'm trying to pull this project and put the Rallare fork into my current tree in place of the existing nrf directory as described above.

However, when I do the west update I get the following. What is wrong?

Hi Alan,

You have an outdated west tool.

Please upgrade with the command: 

pip install west -U

Then to check the version:

west --version
