Hostname in nrfConnect settings is not set when running code

[hmichel]

I have set the host name to my aws thing endpoint name per the instructions on the following link

developer.nordicsemi.com/.../README.html

but the hostname ends up blank as you can see in the watch window at the breakpoint

and the settings are show below

and a search on the name in files finds it set in the zephyr.elf and other generated files

Why is the hostname blank?

Hello,

When you have stopped on line 385 in Segger Embeddes Studio, this line has not yet been executed. Try to set the breakpoint on the next line, and then check the hostname pointer in watch. 

Best regards,

Edvin

I hit same breakpoint then did a debug "step-over" with still the same result

The hostname is set in the calling function

With the define CONFIG_MQTT_BROKER_HOSTNAME

which is set to mqtt.eclipse.org

[hmichel]

And with "optimize for debug" turned back on it works

[Edvin]

Hello,

Can you please try to enable some debug logging on some of the modules from your menuconfig, and then let me know what the log says when optimization isn't enabled:

MQTT_LOG_LEVEL_DBG
NET_ROUTE_LOG_LEVEL_DBG
NET:_CONN_LOG_LEVEL_DBG
AWS_JOBS_LOG_LEVEL_DBG
AWS_FOTA_LOG_LEVEL_DBG
DFU_TARGET_LOG_LEVEL_DBG

I don't see where I set or select those in menuconfig

Also did you see my screen shots about trying the json file as you had suggested?

[Edvin]

If you search for "LOG_" in menuconfig, they should turn up. 

Regarding the json file: It looks like you are missing a comma after "size": 232128, 

Try to add this, and see if it still reports it as an invalid file.

I found the LOG_ entries. However, for some reason I am getting the following error

LTE Link Connected!

IPv4 Address 3.130.92.97
client_id: nrf-352656100047698
ERROR: mqtt_connect -45

And last night the device connected several times right before I stopped working. So I have a different problem I need to fix before I can test your suggestions.

Thank you for seeing the missing "," in the json file. Simple beginner mistake

[hmichel]

I fixed my error. I will try your suggestions now

[hmichel]

I could not find NET_ROUTE_ and NET_CONN. But I set all the others. Set "Optimize for size"

Here is the terminal log. It seems like the LTE won't connect with those settings

[Edvin]

Hello,

I see that you are getting help regarding the same issue from my colleague in your other ticket. I think he has more knowledge about the application that you are working on, so unless you see a specific reason, I suggest that you follow up in that ticket.

BR,

Edvin
