Describe the bug Previously, mqtt was working with hl7800 with zehyr3.6.0. After migration, i started getting this error:

Please also mention any information which could help others to understand the problem you're facing:

To Reproduce Steps to reproduce the behavior: because I am working on custom board, I cant exactly provide steps to reproduce it.

Expected behavior at 3.6.0 version, I had succesfull getaddrinfo return and mqtt connection

Environment (please complete the following information):

zafersn commented 3 days ago

Anyone ask for additional information on this issue? I am still trying to fix it but have not been able to do that so far. And also, Anyone who can shed some light on where the possible issue is and how to debug it will be appreciated

rerickson1 commented 2 days ago

@zafersn based on the log message output you are using a modified HL7800 driver and not the one in the tree. Please provide logs from an unmodified driver.

rerickson1 commented 2 days ago

@jukkar can I get the label platform: Laird Connectivity changed to platform: Ezurio. Laird Connectivity is no longer valid because we have renamed the company.

zafersn commented 1 day ago

hi @rerickson1 I was working on a custom driver based on your company's provided hl driver, thanks for that. I just created an sample app with default hl7800 driver, and the result is the same.

P.S. I have lots of debug messages in net_dns_resolve:, socket files. please ignore them..

here is the logs belongs to the hl7800 driver:

Thanks for the logs, could you share the sample app so I can try to reproduce?

@rerickson1

cellular_hl7800-git.zip

this is exactly what i was doing for you :)

rerickson1 commented 1 day ago

@zafersn I cannot get the sample to build, it gets in an endless cmake loop. Also, the sample isnt configured to use the HL7800 driver... build.log

zafersn commented 1 day ago

@rerickson1 in my case, I used nucleo_u575zi_q.overlayand nucleo_u575zi_q.conf. So, it must be configured in my case, which I got all the logs shared them with you, and lte nbiot connection. please see the logs here :https://github.com/zephyrproject-rtos/zephyr/issues/75398#issuecomment-2211302024 . ILL have a look at your logs.

zafersn commented 1 day ago

I see in your logs, I just sent the prj.conf file to you with a different cellular apn config, just in case, wanted to hide some information, I am sharing everything publicly here. Please set this config something else.

CONFIG_MODEM_CELLULAR_APN="netfe*****"

and rest of the cmake warning is because of you probably didnt use board.conf file. Sorry for this comlexity, I just built the test app on already exist zephyr sample for modem test

zafersn commented 1 day ago

@rerickson1 please try this sample app,

I have reproduced the dns issue with the http get sample. Patch: hl7800_http_get.patch Log: http_get_3.7.0-rc2.log

It seems the socket packet source address may not be set correctly due to a change in the stack. @jukkar any tips?
