nRF Cloud Multi-service Quick Start is Working, But compiling with nRF7002 Shield can't connect to nRF Cloud

[PhilWare]

Hi,

I am using a nRF9161-dk with the nRF7002-ek shield WiFi tracking.

Using the nRF Connect Quick-Start, I downloaded the nRF Cloud Multi-service application and went through provisioning, and I can see my device on my nRF Cloud account, using the cellular and GPS tracking.

Because I need to review the nRF7002 WiFi Tracking with the Shield device, I downloaded the source code and added the extra configs and selected the shield.

-DSHIELD=nrf7002ek_nrf7000 -DSB_CONF_FILE=sysbuild_nrf700x-wifi-scan.conf -DEXTRA_CONF_FILE=overlay-nrf7002ek-wifi-scan-only.conf

This compiles OK and I can program/flash it on to my dev kit.

The application runs OK and connects to the LTE-M network, but with my own compiled version I am now getting this error:

[00:12:04.663,665] <err> nrf_cloud_transport: MQTT input error: -128
[00:12:04.663,726] <err> nrf_cloud_transport: Error disconnecting from cloud: -128
[00:12:04.663,787] <inf> cloud_connection: Disconnecting from nRF Cloud
[00:12:04.663,818] <err> cloud_connection: Could not connect to nRF Cloud
[00:12:04.663,818] <inf> cloud_connection: Retrying in 30 seconds...

I have verified the token is still valid and provisioned by using this command: AT&ATTESTTOKEN

nRF Cloud says it is valid and already claimed.

What do I need to do to the source code to allow it to connect back to my nRF Cloud account?

Thanks,

Phil.

Hi,

Can you show complete build command which you used?

There are some useful debug options in documentation. Can you try to enable debug logging for the sample using CONFIG_MULTI_SERVICE_LOG_LEVEL_DBG=y and provide new log?

Best regards,
Dejan

[PhilWare]

I'm not sure why I am now seeing a different error code (-111), but from this log it is clear that the LTE-M connection is not very good at all and is probably causing the flaky connection issues.

I will try in a better location and hopefully that will work better

For comparison, please provide your testing results from different location.

error -111 means connection refused and is probably caused by incorrect root CA certificate for MQTT and HTTP.

When nRF Cloud multi-service sample provisions the device to the nRF Cloud it uses UUID for device identification. If the sample is rebuild without provisioning overlay IMEI is used for identification. This causes the connection issue. Please add below kconfigs to prj.conf when building the sample without provisioning overlays

CONFIG_MODEM_JWT=y

CONFIG_NRF_CLOUD_CLIENT_ID_SRC_INTERNAL_UUID=y
