nRF9160 to Google Cloud Pub/Sub: Build errors

[T1mS_]

Hi,

I followed this guide to send data to the GCP using the Thingy:91 : https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/how-to-connect-nrf91-to-google-cloud

Im pretty sure I did it correct and followed all steps listed there.

But I can't get it to build. I tried it with the v0.4.0 tag and also master, cause this was recommended here in the forum.

This is my build error log:

Any help is appreciated!

Hi,

I fixed the error. After moving the whole directory to the c drive root instead of using all these sub folders.

After writing the hex file to the thingy:91 this is the serial output. Did messed something up with the certificates?

Hi,

Have you tried with version v1.0.0 of ncs?

Also, to get more information about when the hard fault happened, you can open the file /build/zephyr/zephyr.lst and search for your faulting instruction address, which is 1921c in the output above.

Hi ,

I tried it again today and now I get error -13.

I tried to find some information about the error number but can't find any.

Hi Tim,

In order to find what error number -13 is, you can use strerror().

printk("err: %d\n", strerror(-err));

This will print what error number -13 corresponds to. You can add this where the following is in the code

LOG_ERR("mqtt_input failed: %d", err);

That is, line 635 in gcloud.c

strerror() must take a positive error number, hence the minus in front of err in the code above.

Hope this helps.

Best regards,

Marte

Hi ,

now it works. The problem was in the Google Cloud I guess. Something with the certificates. The error was "connection refused" so I added the device again to the cloud.

Hi Tim,

Yes, connection refused does sound like a problem with certificates or how the device was added on Google Cloud.

Great that you managed to solve it!

Hi

I am facing the same above issue while connecting my Thingy91 PCA20035 device to Google cloud uisng MQTT bridge.

I have placed nRFDKtoGoogleCloud folder inside the ncs-folder, for example giving the path \ncs\nrf\samples\nrf9160\nRF9160DKtoGoogleCloud.

I followed this guide to send data to the GCP using the Thingy:91 : https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/how-to-connect-nrf91-to-google-cloud

I m pretty sure I did it correct and followed all steps listed there.

After writing the hex file to the thingy:91 this is the serial output.

This is my build error logs:
