Hi all,
I am new in the wonderfull embedded module developement of SiWi.
Well, I am presently using a Q26 wireless module which is integrated in a design. I want to display some informations gathered from the UART2, and display it on UART1, here is my code, I found it in this forum and please have a look on it :
/*

}Actually, the App shows me permanently :
UART2: Data Mode
+WIND: 1
+CREG: 2
+WIND: 7
+CREG: 1,"0007","1ECA"
+WIND: 4
+WIND: 3
+CREG: 0
+CGREG: 0Again and again
I will apreciate your help!
