Hiya,

Looks like you’ve got a mismatch between the firmware version in your device, and the application environment that you’ve used to develop your program.

Make sure that the firmware version installed in your module and Open AT (Application) Framework package match. You can check the module by using

```auto
ATI9
```

and the development environment by right clicking on your project, then select Properties and Open AT Application. Check the Framework profile matches the OS.

ciao, Dave
