Send and receive string by a sensor rs232

Hello, nice to meet you all,
I have a problem, and searched the forum but did not and found the solution.

I have an extended fxt009, and I need to send a string and get answers from a sensor that communicates via RS232.
I have a code I found on the forum, and also adl_fcmSendData UART communication.

by hyperterminal, sending the string “TEST \ n” and returns me “TEST”
example

“TEST”
<“TEST”

Do not e able to work with the code, I’ll be doing wrong? I need some guidance or information.
attached the code I’m using.

#include "adl_global.h"
#include "generated.h"

static s8 FCM;
static s8 FCMV24;
static s8 fcmData;
static s8 Ipr, Wmfm;
adl_fcmFlow_e flow = ADL_PORT_UART2;

bool HandleWmfmUart2(adl_atResponse_t *response);



void SendData(u8 Id)
{

	TRACE((1,"CTM\n"));
s8 data = "TEST\n";

fcmData = adl_fcmSendData(FCM, data, 5);
TRACE((1,fcmData));

}

bool CtrlHandler(adl_fcmEvent_e event)
{
switch( event )
{
case ADL_FCM_EVENT_FLOW_OPENNED :
TRACE(( 1, "ADL_FCM_EVENT_FLOW_OPENNED\n"));
FCMV24 = adl_fcmSwitchV24State(FCM, ADL_FCM_V24_STATE_DATA);
TRACE(( 1, "adl_fcmSwitchV24State = %d", FCMV24));
break;

case ADL_FCM_EVENT_V24_DATA_MODE :
TRACE(( 1, "ADL_FCM_EVENT_V24_DATA_MODE\n"));
adl_tmrSubscribe(TRUE, 100, ADL_TMR_TYPE_100MS, (adl_tmrHandler_t)SendData);
break;

case ADL_FCM_EVENT_V24_AT_MODE :
case ADL_FCM_EVENT_V24_AT_MODE_EXT:
TRACE(( 1, "ADL_FCM_EVENT_V24_AT_MODE\n"));

FCMV24 = adl_fcmSwitchV24State(FCM, ADL_FCM_V24_STATE_AT);

break;

case ADL_FCM_EVENT_FLOW_CLOSED:
TRACE(( 1, "ADL_FCM_EVENT_FLOW_CLOSED\n"));
adl_fcmUnsubscribe(FCM);
break;

case ADL_FCM_EVENT_RESUME :
TRACE(( 1, "ADL_FCM_EVENT_RESUME\n"));
break;

case ADL_FCM_EVENT_MEM_RELEASE :
TRACE(( 1, "ADL_FCM_EVENT_MEM_RELEASE\n"));

break;
}
}

bool DataHandler(u16 DataLen, u8 * Data)
{
TRACE(( 1, "DataHandler\n"));
return TRUE;
}

bool HandleWmfmUart2(adl_atResponse_t * response)
{
TRACE (( 1, "HandleWmfmUart2Enable\n" ));
FCM = adl_fcmSubscribe(flow, CtrlHandler, DataHandler);
TRACE(( 1, "adl_fcmSubscribe= %d", FCM));
return FALSE;
}

bool HandleIPR(adl_atResponse_t * response)
{
TRACE(( 1, "HandleIPR\n"));
return FALSE;
}

void main_task(void) {
	// TODO Insert your task initialization code here
	TRACE (( 1, "Embedded Application : FCM\n" ));

	Wmfm = adl_atCmdCreate("AT+WMFM=0,1,2", FALSE, HandleWmfmUart2, "*", NULL);
	TRACE(( 1, "adl_atCmdCreate(AT+WMFM)= %d", Wmfm));

	Ipr = adl_atCmdCreate("AT+IPR=19200", ADL_AT_PORT_TYPE(flow, FALSE), HandleIPR, "*", NULL);
	TRACE(( 1, "adl_atCmdCreate(AT+IPR)= %d", Ipr));
}

I hope your help and thanks for reading

best regards :blush:

Hi,

Can you please provide the ADl level traces.
Also in the application,please try to call function adl_fcmSendData() in datahandler.

Thanks.

okey, thanks :smiley:

Any HELP??!!! :neutral_face:
