How many embedded applications?

I just tried the first embedded application. Yay, it is hello_world :slight_smile: . Still pretty happy.
Have a couple of questions after this try.

After downloading the .dwl file into the Q24PL001 modem, in the Hyperterminal, run the application by typing

I got response in the Hyperterminal:
+WIND: 13
+WIND: 1
+WIND: 16
+WIND: 4
+WIND: 10,โ€œSMโ€,0,โ€œFDโ€,0,โ€œONโ€,0,โ€œSNโ€,0,โ€œENโ€,0
+WIND: 11,โ€œ351252EA93CA5C332655C3FFB461076Cโ€,


  1. I have actually downloaded two applications into the modem, but hello_world is the last one. In at+wopen=1 command, no application is specified. Does this mean that Q24 modem only supports one application? and downloading new application will erasing the previous application?

  2. What do the +WIND lines mean?

Thanks for your response.

  1. YES

  2. +WIND are โ€œIndicationโ€ messages, consult the AT Commands guide for more information about how to handle/enable/disbale it.
