}

here in the above program with respect Q2687 in M2M studio 1.0 . In my hardware the uart2 port is connected to the GPS module and and i am receiving data from uart2 and has to send to uart1. In my program the uart2 is not responding .

You need to open UART2 before you try to subscribe to the FCM flow:

// Activate UART2
   adl_atCmdCreate("at+wmfm=0,1,2", FALSE, NULL, NULL);

   // Disable handshake
   adl_atCmdCreate("at+ifc=0,0", ADL_AT_PORT_TYPE(ADL_PORT_UART2, FALSE), NULL, NULL);

   // Set BAUD Rate
   adl_atCmdCreate("at+ipr=9600", ADL_AT_PORT_TYPE(ADL_PORT_UART2, FALSE), NULL, NULL);
