Read and write on UART1

IoT Gateways Legacy FX/FXT series

Hi there,

I’m new to Sierra Wireless programmable module and I need the community help.

I have e GL6100 RS232 module.

My goal is Read and Write byte from UART1. To do this I followed the sample project created with Developer Studio (2.3.2).

This is my code:

void UART_WriteCb( u8 ID, void * Context )
{
	TRACE(( 2, "UART Write callback"));
	uart_if->write( uart1_handler, "Uart opened", 13);
}


/***************************************************************************/
/*  Function   : main_task                                                 */
/*-------------------------------------------------------------------------*/
/*  Object     : Customer application initialisation                       */
/*                                                                         */
/*-------------------------------------------------------------------------*/
/***************************************************************************/
void main_task ( void )
{
	sUartSettings_t settings;
	sUartLc_t 		line_coding;

	//adl_InitType_e adl_InitType = adl_InitGetType ();
    TRACE (( 2, "Embedded : Application Initialized" ));

    /* Write on UART */
    //adl_atSendResponse ( ADL_AT_UNS, "\r\nMain task started\r\n" );

    /* UART1 Configuration */
    TRACE (( 2, "Configure UART1" ));

    /* Set the line code parameters */
    line_coding.valid_fields	= UART_LC_ALL;
    line_coding.rate 			= (eUartRate_t)( UART_RATE_USER_DEF | 115200 );
    line_coding.stop 			= UART_STOP_BIT_1;
    line_coding.data 			= UART_DATALENGTH_8;
    line_coding.parity 			= UART_PARITY_NONE;

    /* Set the UART parameters */
    settings.identity 			= "UART1";
    settings.role 				= UART_ROLE_NM;
    settings.capabilities 		= NULL;
    settings.event_handlers 	= NULL;
    settings.interface 			= &uart_if;
    settings.line_coding		= &line_coding;

    uart1_handler = adl_OpenDevice( DF_UART_CLID, &settings );

    if( uart1_handler == ERROR)
    {
    	TRACE (( 2, "UART opening error" ));
    }
    else
    {
    	TRACE(( 2, "UART opened"));
    	/* Start time to write periodically on UART */
    	adl_tmrSubscribe ( TRUE, 10, ADL_TMR_TYPE_100MS, UART_WriteCb );
    }
}

I start a timer and when the timer elaps, I want to write on UART1.

To wirte this code I followed the example reported into “OpenAt Tutorial” under “Chapter17 - Open Uart”.

The problem appear when I try to open UART1. The port cannot be opened.

But if I use UART2 the port can be open.

By the way, i use the tab “Target Management” in Developer studio, to view the trace from the target.

Thanks for the help!

Hi,
in which port you are running the application? if it’s on UART them i don’t think you can subscribe to it via application.

Also you can check UART1 status using AT+WMFM command
