I tried to work httpGet(sample code) on WP7605.  
But, it don’t work on WP7605.  
The following is a part of logread output.  
“failed to read /etc/resolv.conf: Permission denied”

Why no permission?

Using “chmod o+x /etc/resolv.conf”, I can confirm httpGet sample code working.  
But, that’s no good, because the permission of /etc/resolv.conf is updated automatically.

Devlopment enviroment : Vscode (Legato Plugin for VSCode, swi-wp76\_5.0.4)  
Device: WP7605

Please tell me what I should do.  
Best regards, Akihito Fujikake.

Here says you need to use unsandboxed app or using real ip address inside the .c file

Or you can try swi-wp76\_5.2.0 with legato 20.08

> seems related to this one: I remember when I used the httpget sample with WP76 module, there is same problem of getting IP address inside application and this is fixed in later FW with legato 20.04. Currently you might try method to get IP addres inside program:

Using “sandbox: false”, httpGet sample stated to work.  
Thank you very much, jyijyi!!
