Hello,

Have a look at the Zephyr documentation here. Specifically, the thread section and k_thread_priority_set() can be of help.

Kind regards,

The k_work_submit routine has not changed the last three years.

Have you ensured that you have the correct priority on your routines?

Please do so.

As we want to find why calling "getaddrinfo" through "k_work_submit" fails.

Ok, good to hear you found a solution!

I would compare the Zephyr BSD socket chapters between v1.0.0 and v1.1.0 if you need more information.

Hi,

"connect_to_provision" is made by us. We call "getaddrinfo" in this function.

I was calling "connect_to_provision" through "k_work_submit" (scheduler) but now i have stopped calling it from "k_work_submit".

Hello,

[quote user="khodidas"]We have "connect_to_provision" function in which "getaddrinfo" function is being called.[/quote]

What is "connect_to_provision"? What does this function do? It's not a function in NCS.

Hi,

I have just found the solution to this problem.

We have "connect_to_provision" function in which "getaddrinfo" function is being called.

We call "connect_to_provision" through "k_work_submit(&connect_to_provision_work)".

I removed calling "connect_to_provision" function through "k_work_submit" and called it directly.

After that system doesn't get stuck in "getaddrinfo" function.

Calling "connect_to_provision" through "k_work_submit" was working with NCS v1.0.0.

Can you tell me why same thing is not working with NCS v1.1.0 ?

Yes, my application was working before moving to 1.1.0. My application is based on "http application update" sample example.

[quote userid="77062" url="~/f/nordic-q-a/57025/nrf9160-system-gets-stuck-in-getaddrinfo-function/231134"]Are you getting any error messages? When and where are you calling the function in your application? I will need some more information about the application to be able to help.[/quote]

No i am not getting any error message. It just gets stuck inside "nrf_getaddrinfo" function. I am calling "getaddrinfo" function after modem connects with network. There is delay of 1 second after connecting with network.

I will try to tell you signal strength tomorrow. But there doesn't seem to be issue of signal strength as if i run "mqtt_sample" example in same hardware then i get address from "getaddrinfo" and also connecting with server without issue.

[quote user=""][/quote]

In new sdk v1.1.0 ,When i try to get Address of the server using "getaddrinfo" system gets stuck in that function.

I debugged it and found that it gets stuck in "nrf_getaddrinfo" function inside "getaddrinfo".

Are you getting any error messages? When and where are you calling the function in your application? I will need some more information about the application to be able to help.

[quote user=""]As mentioned in the case , I verified the LTE connection. I always call "getaddrinfo" after LTE connection.[/quote]

And as mentioned by my colleague in that ticket:

"How is the signal strength where you are testing? If you are certain you are connected to the network, and the signal strength is good could you take a modem trace when getaddrinfo hangs, so that we can analyze further?"

Thanks!
