open at can't run my hello_world?

Hi, I’m new in openat, I use eclipse + open at plugin to devlelop a hello world. But When run the “hello world” as openat target, I got nothing in trace view. here’s my log of shell.

at+wdwl
+WDWL: 0
*** ERROR IN HEADER ***
at
OK
at+cfun=1
OK

what’s wrong with my program, or my open at sdk?

Are you downloading *.dwl file? Did you compiled your hello_world with correct SDK and for your module type?

Try to upgrade downloader like this:

  1. Get the latest firmware and look for dwl.dwl file in it.
  2. Download this file into your module.
  3. Restart module.
  4. Try to download your hello_world again.

The type of error indicates probably wrong sdk for the modem, for example you are using Q24 and you have not imported the Q24 SDK from the old open at ide
