I am working with a Fastrack Supreme 10 , and I have a lot of applications working with wip library that work fine on Fastrack Supreme ,  
but when i load the .dwl file on the Developement Kit Q26 , wip initializes correct , the wip\_BearerOpen returns 0 ( OK ) but wip\_BearerStart always returns  
WIP\_BEER\_BAD\_HDL ( -24 code) , and i tried to find to find a solution but i couldn’t .

Somebody , please help me !

Is there a posibility that the firmware from Fastrack Supreme to be so different from the one on the Developement Kit ?

Thank u ,

Are you sure you are using same firmware versions on both?

I solved it , the DK was set on the US Band 🙂

So, wasn’t it obvious that the DK wasn’t GSM registering at all - which is a prerequesite for doing anything at all (including WIP) over the radio link?
