Ability to set custom timeout for getaddrinfo?

[Cody]

Hello,

When operating the Thingy91 in poor network connectivity environments, the call to getaddrinfo will sometimes block and eventually timeout returning a error code 60 (ETIMEDOUT).

Is there a way to set a specific/custom timeout for getaddrinfo?
EDIT: Based on Didrik Rokhaug's response in the following ticket, it looks like the answer is no. (https://devzone.nordicsemi.com/f/nordic-q-a/55840/getaddrinfo-in-can-block-indefinitely-after-lte-connect)

Do you know what the timeout for getaddrinfo is by default?
If there is no way to set a timeout for getaddrinfo, is there a workaround?

Thanks,
Cody

Hi again!

getaddrinfo() in BSDLib returns ETIMEDOUT, if the DNS server can't be reached or isn't answering. I'm still waiting on information regarding the specific time it waits before returning the error so I will get back to you on that. 

A workaround could be to not look up the address but have ut saved statically in the application.

Best regards,

Heidi

Hey Heidi,

Any update on how long the timeout is for getaddrinfo()?

Thanks,

Hi! Yes, they say the specific time is 1 second.

Hi, just to be more specific for other viewers:

The modem has four re-transmissions for the DNS query. The timeout for the first DNS request is 1 second and the timeout for the second, third and fourth DNS request is 3 seconds.

 All together this means a 10 second timeout in the RPC interface.
