UART port on CC2538 with Zstack

Can you specify which Z-Stack version and example you test this?

It's the latest Zstack. I used heneric application but this code I wrote will not reach aplication. I wanted it to continuously send on serial port.

What do you mean heneric example?

THat was a type I meant generic.

Thank you. So when you run my code, you can see MT commands on your PC with a terminal application?

Yes, I can see it.

Thank you very much for the time and help.

You are welcome .

Sorry I have to get back to this.

When I add the posted code to ZMain.c, my device only runs it once. I can't understand why it doesn't loop forever (while(1)) .
Do you have any idea what might cause this? Whenever I reset the device it only sends the MT command composed only once. Even in debug only runs it once.

Do you use SampleLight to test this?

No I used sampleSwitch. Should it matter? Because it doesn't get to run the actual application.

It doesn't matter but I don't think it is a good idea to put this MT command code in main function. Anyway, I test it in SampleLight and see it works fine. You can replace the following code to yours and test again.

int main( void )
{
// Turn off interrupts
osal_int_disable( INTS_ALL );

// Initialization for board related stuff such as LEDs
HAL_BOARD_INIT();

// Initialize board I/O
InitBoard( OB_COLD );

// Initialze HAL drivers
HalDriverInit();

// Initialize NV System
osal_nv_init( NULL );

// Initialize the MAC
ZMacInit();

// Determine the extended address
zmain_ext_addr();

#if defined ZCL_KEY_ESTABLISH
// Initialize the Certicom certificate information.
zmain_cert_init();
#endif

// Initialize basic NV items
zgInit();

#ifndef NONWK
// Since the AF isn't a task, call it's initialization routine
afInit();
#endif

// Initialize the operating system
osal_init_system();

// Allow interrupts
osal_int_enable( INTS_ALL );

SysTickSetup();

// Final board initialization
InitBoard( OB_READY );

/* Display the device info on the LCD */
#ifdef LCD_SUPPORTED
zmain_dev_info();
zmain_lcd_init();
#endif

#ifdef WDT_IN_PM1
/* If WDT is used, this is a good place to enable it. */
WatchDogEnable( WDTIMX );
#endif

MT_UartInit();
while(1)
{
uint8 p[12];
p[0]=0xFA;p[1]=0xCE;
p[2]=0xAB;p[3]=0xCD;
p[4]=0xEF;p[5]=0x01;
p[6]=0x23;p[7]=0x45;
p[8]=0x67;p[9]=0x89;
p[10]=0x02;

MT_BuildAndSendZToolResponse(((uint8)MT_RPC_CMD_AREQ | (uint8)MT_RPC_SYS_ZDO), MT_ZDO_END_DEVICE_ANNCE_IND, 0x0B, p);
for (int cnt=0;cnt<65530;cnt++){
;
}
}
osal_start_system(); // No Return from here


return 0; // Shouldn't get here.
} // main()

Thank you. Shouldn't allocate memory and free it for p?

p = osal_msg_allocate(12);
osal_mem_free(p);

ceive something on serial port continuously, but it's not what is being sent. it is all 0's:

It's just personal preference. I prefer to use static array instead of memory allocation in case I forget to free allocated memory.

You should set baudrate to 38400.

Thank you very much. It seems problem was with allocate and free memory I used for p. With your code it works fine.

You are welcome and it's good to know it works now.
