First boot after modem FOTA results in at_cmd error

I am facing the same issue(need reboot modem twice after its FOTA), and the bsdlib_get_init_ret() always returned -1, why? I have defined CONFIG_BSD_LIBRARY=y

If -1 indicated fatal error, what operations are required before invoking bsdlib_init()?

My bad, it was from another private ticket. Here's an excerpt;

"There has been an update in NCS on handling modem FOTA.

Have a look at the main file of http_application_update, the switch case is based on the return code from bsdlib_init(), however, this should be changed to bsdlib_get_init_ret.

The system needs to be rebooted twice after downloading the modem FOTA, and changing the above should solve the issue. Let me know how that works for you."

Hey Hakon,

The link you referenced doesn't seem to be working. I'm getting a browser error (tried with both Chrome and Firefox):

ERR_TOO_MANY_REDIRECTS

Hey,

You try implementing any of the fixes mentioned here. I don't know what you are doing in your code specifically, but the post I linked to seemed to have the same error as yours.
