This was the issue nevermind. I appreciate the help!

Hi,

I do not believe this is the case, as the cloud also sees the same message. Could something else be the cause? Thanks, Ryan

Hi,

This issue might be related to float logging. You can look at this discussion (adding CONFIG_CBPRINTF_FP_SUPPORT=y) and this issue.

No I did not receive the same error from the example codes. I am not sure as to what exactly I changed to make it work, I do believe it was now a CONFIG issue as now the code does work without fail each time.

I have a follow up issue. The code I have does upload, but it doesn't upload the numerical value but prints *float* instead of a number.

I'm not sure as to what the issue is as I've tried replacing the value and remains the same. The function, sensor_value_to_double or any double value returns the *float* text.

static int send_data_to_cloud(struct sensor_value *temp, struct sensor_value *hum, struct sensor_value *light)

{

int ret;

cJSON *root;

char *json_str;

// Temperature

root = cJSON_CreateObject();

if (!root) {

LOG_ERR("Failed to create JSON object");

return -ENOMEM;

}

cJSON_AddStringToObject(root, "appId", "TEMP");

cJSON_AddNumberToObject(root, "data", sensor_value_to_double(temp)); // Must be a number

cJSON_AddStringToObject(root, "messageType", "DATA");

json_str = cJSON_PrintUnformatted(root);

if (!json_str) {

LOG_ERR("Failed to create JSON string");

cJSON_Delete(root);

return -ENOMEM;

}

struct nrf_cloud_tx_data temp_msg = {

.data.ptr = json_str, .data.len = strlen(json_str),

.qos = MQTT_QOS_1_AT_LEAST_ONCE, .topic_type = NRF_CLOUD_TOPIC_MESSAGE

};

LOG_INF("Sending temp: %s (value: %f)", json_str, sensor_value_to_double(temp));

ret = nrf_cloud_send(&temp_msg);

cJSON_free(json_str);

cJSON_Delete(root);

if (ret) return ret;

(for example, it outputs)

[00:48:44.018,432] <inf> main: Temp: 18.460000°C, Humidity: 41.272460%, Light: 155.000000 lux [00:48:44.018,798] <inf> main: Sending temp: {"appId":"TEMP","data":float,"messageType":"DATA"} (value: *float*) [00:48:44.029,113] <inf> main: Sending humid: {"appId":"HUMID","data":*float*,"messageType":"DATA"} [00:48:44.030,151] <inf> main: Sending light: {"appId":"LIGHT","data":*float*,"messageType":"DATA"} [00:48:44.781,890] <inf> main: Unhandled LTE event: 3

I provided the main.c file and the prj,conf file.

Hi Ryan,

[quote user="dejans"]Do you get the same error when you use separately unmodified nrf_cloud_rest_device_message and nrf_cloud_multi_service samples?

How did you provision (and onboard) your device?[/quote]

Can you provide answers to these questions?

[quote user="RyanSG"]I have resolved the previous issue.[/quote]

Can you provide some details about this?

Can you please provide details about the application that you used when you got the log you shared? Have you tried to use unmodified nrfcloud_multi_service sample?

Hi,

I am using the nRF9161DK.

I have resolved the previous issue. However, now the code does not hold a connection to the Cloud. It temporarily connects at the beginning. I will read through more of the sample code to fix the issue hopefully.

Hi Ryan,

Which device do you use for testing?

Do you get the same error when you use separately unmodified nrf_cloud_rest_device_message and nrf_cloud_multi_service samples?

How did you provision (and onboard) your device?

Best regards,
Dejan

Hi, I based this code off the nrf_cloud_rest_device_message and the nrf_cloud_multi_service codes. I changed to main and now the CONFIG works, however I still have the same error without changing the code. So it was not the CONFIG but possible credential issue.

Hi Ryan,

Which application sample did you use as basis for your application?

Regarding inability to use CONFIG_NRF_CLOUD, I can see that this option is not used in NCS v2.9.0 (in nRF Cloud multi service sample) but it is used in main. Can you try to use main instead of NCS v2.9.0? What is the result?

Best regards,
Dejan

Hi.

I have been working on the code for a while and was reading documentation on the CONFIG_NRF_CLOUD or nRF Cloud API as a way to send my data to the cloud. However, I noticed that the library does not appear for me and saying 'undefined symbol'. I am not sure why the SDK does not see the library. I am on the latest toolchain v2.9.1.

If I remove the config and let the code run, I am returned an error. I have tried checking ID, and updating to no avail.

Hi,

You can start by looking at Getting Started with nRF Cloud and then you can look at cellular samples in the documentation.

Best regards,

Hi,

I can look again later today. This is not based on any official Nordic example, just examples found online elsewhere using Zephyr API for the sensors. If there are any good recommendations, I can take a look.

Hi,

I cannot see proper build log in your rar file. Can you check if there is a proper file inside your rar file?

Is your application based on any of our samples?

Best regards,
Dejan

It seems I forgot to mention that it is the nRF9161DK. My bad.

My build configuration is the following.

Build Command:

west build --build-dir --pristine --board nrf9161dk/nrf9161/ns -- -DNCS_TOOLCHAIN_VERSION=NONE -DBOARD_ROOT=c:\Users\RS_G\workspace\cloud-test

dejans — Thu, 06 Mar 2025 15:49:13 GMT

Hi,

Which device do you use?

Do you use any of our samples as basis for your application and for your testing?

Can you show your build command and provide complete build log? You could upload your build log by first making zip file and then clicking on Insert -> Image/video/file -> Upload.

Best regards,
Dejan
