9160 Network connection is abnormal when the FOTA function is running

[duxinglang]

I am learning and testing the FOTA function of the 9160. I have verified that it works with the official http_application_update project, but when I test it with my own project, I find that the device only gets a packet of data from the background after each startup.  Then send the http request again when the network exception is displayed, and then reconnect can be successfully connected and obtain data once, and then display the second request data failure, what is the cause of this?  the logs is like this:

Hi,

 

I am learning and testing the FOTA function of the 9160. I have verified that it works with the official http_application_update project, but when I test it with my own project, I find that the device only gets a packet of data from the background after each startup.

Did you point the http_application_update project to the same URL as you're testing now?

 

Q1: Can you share information about which ncs and modem fw you're using?

Q2: Could you share your prj.conf?

 

Kind regards,

Håkon

Thank you for your reply. I have found the reason, because my project is starting  

At the same time of FOTA, there were other tasks running, which caused the connection between the terminal and the background timed out. Our background engineer modified the setting of automatic connection disconnection after timeout, and the connection was normal!
