Hi,

Which tag on NCS did you checked out? and which modem version are you using?

You should try to test hosting your image on nRF cloud first and see if that works. If you are setting up your own http server you server needs to support 'CONTENT-RANGE' header in http.

Yes, I changed it from default 1 to 2.

I even setup a http server but failed to DFU on LTE.

Hi,

Sorry for the late reply. Have you changed the application version to 2 (or higher depending on what you have used before)?

Best regards,

Marjeris
