Could not change uart1 to data mode

Legacy Open AT
1

hi,
i am trying to do coding for UART1(Q24EXTENDED)…i am suceeded in subcribing it after that i cant change the mode to data…adl_fcmSwitchV24State(FCM_UART1_handle,ADL_FCM_V24_STATE_DATA);i think this function is not working.But this code is working fine if i use this code for UART2 i am able to change it to data mode.
pl somebody help me

what do you think is not working? do you get an error code?

Actually im not gettin any error code…But UART1 is not changing its mode(from AT to DATA)after the flow is opened.This same code works fine if i change the UART…That is UART2 instead of UART1…With UART2 i can change the mode to DATA once the flow is opened.Here is my code…

#include “adl_global.h”

u32 wm_apmCustomStack [ 256 ];
const u16 wm_apmCustomStackSize = sizeof ( wm_apmCustomStack );
s8 V24handle;

bool FcmCntrlHandler (adl_fcmEvent_e event)
{
adl_atSendResponse ( ADL_AT_UNS,“\r\n CONTRL HANDLER\r\n”);
switch (event)
{
case ADL_FCM_EVENT_FLOW_OPENNED:
adl_fcmSwitchV24State(V24handle,ADL_FCM_V24_STATE_DATA);
adl_atSendResponse (ADL_AT_RSP, “\r\nCtrl is in case 1:Flow Opened\r\n” );

  break;

  case ADL_FCM_EVENT_FLOW_CLOSED:
      //MaySend=FALSE; 
  break;

  case ADL_FCM_EVENT_V24_DATA_MODE:
     // MaySend=TRUE;
	  adl_atSendResponse (ADL_AT_RSP,  "\r\nCtrl is in Case 3:DATA MODE\r\n" );
      //adl_tmrSubscribe ( TRUE, 900, ADL_TMR_TYPE_100MS, ReadEasy_TimerHandler );
  break;

  case ADL_FCM_EVENT_V24_DATA_MODE_EXT:
	   adl_atSendResponse (ADL_AT_RSP,  "\r\nCtrl is in Case4:DATA MODE EXT\r\n" );
	   //MaySend=TRUE; 
  break;

  case ADL_FCM_EVENT_V24_AT_MODE:
	   adl_atSendResponse (ADL_AT_RSP,  "\r\nCtrl is in Case4:AT MODE\r\n" );
	   //MaySend=FALSE; 
  break;

  case ADL_FCM_EVENT_RESUME:
  break;

  case ADL_FCM_EVENT_MEM_RELEASE:
  break;

}
return TRUE;

}

bool FcmDataHandler (u16 DataLen, u8 * Data)
{
adl_atSendResponse ( ADL_AT_UNS,“\r\n DATA HANDLER\r\n”);
return TRUE;
}

void timer_handler(u8 id)
{
adl_atSendResponse ( ADL_AT_UNS,“\r\n TIMER HANDLER\r\n”);
V24handle=adl_fcmSubscribe(ADL_PORT_UART1, FcmCntrlHandler, FcmDataHandler);
}

void adl_main ( adl_InitType_e InitType )
{
TRACE (( 1, “Embedded Application : Main” ));
adl_atSendResponse ( ADL_AT_UNS,“\r\n MAIN\r\n”);

adl_tmrSubscribe(FALSE,10*10,ADL_TMR_TYPE_100MS,timer_handler);

}

I think the problem might be that you should not use “adl_atSendResponse” in data mode… Maybe that is switching you back to AT mode. There are special fcm_ functions to send data through a flow… That also might explain that it is working with UART2 since the "adl_atSendResponse"s are still sent through UART1 and not to UART2. That’s why this is not impacted…

Hopefully, that is it… Otherwise, I have no idea…

thanks a lot jan
