RTOS/CC2650: LaunchPad CC2650, can't read from UART!

You don't have to use teraterm. You can use any terminal tool like hypertermimal in Windows system.

Hi, can you post the code that you used to obain GPS co-ordinates? 

I can get it on Arduino, struggling to get it on CC2650. 

Thanks

Sir i am reading the GPS value using UART_read like following

static unsigned char rxBuffer[20];
static unsigned char ret;
/*
* Application LED pin configuration table:
* - All LEDs board LEDs are off.
*/
PIN_Config ledPinTable[] = {
Board_LED1 | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX,
Board_LED2 | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX,
PIN_TERMINATE
};

/*

* Task for this function is created statically. See the project's .cfg file.
*/
Void echoFxn(UArg arg0, UArg arg1)
{

char input;
UART_Handle uart;
UART_Params uartParams;
const char echoPrompt[] = "\fEchoing characters:\r\n";



/* Create a UART with data processing off. */
UART_Params_init(&uartParams);
uartParams.writeDataMode = UART_DATA_BINARY;
uartParams.readDataMode = UART_DATA_BINARY;
uartParams.readReturnMode = UART_RETURN_FULL;
uartParams.readEcho = UART_ECHO_OFF;
uartParams.baudRate = 9600;
uart = UART_open(Board_UART0, &uartParams);

if (uart == NULL) {
System_abort("Error opening the UART");
}
else{
System_printf("UART communication done");
}



ret = UART_read(uart, rxBuffer, sizeof(rxBuffer));
System_printf("The UART read %d bytes\n", rxBuffer);



// UART_write(uart, echoPrompt, sizeof(echoPrompt));

/* Loop forever echoing */
while (1) {
// ret = UART_read(uart, rxBuffer, sizeof(rxBuffer));
UART_read(uart, &input, 1);
//System_printf("The UART read %d bytes\n", rxBuffer);

UART_write(uart, &input, 1);
}
}

/* Call board init functions */

taskParams.stack = &task0Stack;

System_printf("This example does not attempt to minimize code or data "

System_printf("Data = %d \t ",rxBuffer);

System_flush();

"SysMin. Halt the target to view any SysMin contents in "
"ROV.\n");
/* SysMin will only print to the console when you call flush or exit */
System_flush();

/* Start BIOS */
BIOS_start();

return (0);
}


but i could not understand whether i am able to read the values or because i am not able to print the values. i tried to print the received values using System_printf in the echoFxn function but it is not printing. then i defined the variable as global and when i print it in main function using System_printf i get some value but not exactly sure it is received value or not. Because GPS data contain large number of data but i only get 568793 numbers only. So not able to find whether receiving data or not. please help me and guide me regarding this

Thanks for the Solution. i will try this and inform you. Next time i will take care of not the mix-up the questions in a thread

Did you remove the jumpers that isolate the debugger?

yes i have removed it, and applied your all instructions. but not getting

I wish there was a better way than just sending messages back and forth. Are you not getting a read from  Uart? are you debugging it and you aren't getting any values? Are you using the adafruit GPS? Take a picture of how you have it wired if you can. 

No i am not using Adrafruit GPS. i am using following GPS module.

And i removed the Tx and Rx jumpers. And i have connected GPS Tx to Launchpad Rx and GPS Rx to LaunchPad Tx. and I am Printing the values using System_prinf. Thank you

Could I see your code? Also make sure the baudrate matches the baudrate that your gps device datasheets tell you. 

Hi sorry for the late response. I was busy on some other stuff. my code is for reading data is as following

Void echoFxn(UArg arg0, UArg arg1)
{
int8_t abc[100], bcd[100];
uint32_t RxBytes;
UART_Handle uart;
UART_Params uartParams;

/* Create a UART with data processing off. */
UART_Params_init(&uartParams);
uartParams.writeDataMode = UART_DATA_BINARY;
uartParams.readDataMode = UART_DATA_BINARY;
uartParams.readReturnMode = UART_RETURN_FULL;
uartParams.readEcho = UART_ECHO_OFF;
uartParams.baudRate = 9600;
uart = UART_open(Board_UART0, &uartParams);

if (uart == NULL) {
System_abort("Error opening the UART");
}
else{
System_printf("Uart open");
}

/* Loop forever echoing */
while (1) {
RxBytes= UART_read(uart, bcd, sizeof(bcd));
memcpy(abc,bcd,RxBytes);
UART_write(uart, abc, RxBytes);
}
}

/*
* ======== main ========
*/
int main(void)
{
Task_Params taskParams;

/* Call board init functions */
Board_initGeneral();
Board_initUART();

/* Construct BIOS objects */
Task_Params_init(&taskParams);
taskParams.stackSize = TASKSTACKSIZE;
taskParams.stack = &task0Stack;
Task_construct(&task0Struct, (Task_FuncPtr)echoFxn, &taskParams, NULL);

/* Start BIOS */
BIOS_start();

return (0);
