CC2650DK receive data via UART

Hello Tzuyu,

Please see the article on the BLE Wiki on how to add serial (UART / SPI) to your project. There are a few examples listed.

You can also reference the TI CC2640 BLE to UART TI Design, which is also listed on the TI BLE Wiki.

Best wishes

You can refer to section 6.3.2 UART in SWRU393_CC2640_BLE_Software_Developer's_Guide

In fact , I have already let UART receive data , but I still don't know , How does let data
send to SimpleBLEPeripheral_processCharValueChangeEvt{...} ?

Can you tell me how exactly to do ?

my main.c receiver data via UART function:

char   rx_buffer[20];

char   *ptr;

Uint32 seconds;

char   sec_str[20];

/* Create a UART with data processing off. */

..

..

..

ptr = rx_buffer;

memset(rx_buffer, '\0', sizeof(rx_buffer));

while (1) {

       UART_read(uart, (void *)ptr, 1); //read UART data

       if (isdigit(*ptr)){

        ++ptr;

       } else if (*ptr == '!'){

            *ptr = '\0';

             ptr = rx_buffer;

             seconds = atoi(rx_buffer);

             sprintf(sec_str,"%u",seconds);

             System_printf("receive: %u\n",seconds);

            LCD_WRITE_STRING(sec_str,LCD_PAGE3);

             Seconds_set(seconds + 8 * 60 * 60);

             ptr = rx_buffer;

            memset(rx_buffer, '\0', sizeof(rx_buffer));

}

and SimpleBLEPeripheral.c function SimpleBLEPeripheral_processCharValueChangeEvt{...}

uint8_t newValue;

case SIMPLEPROFILE_CHAR3:
SimpleProfile_GetParameter(SIMPLEPROFILE_CHAR3, &newValue);

if (newValue & 0x10)  //receive 0x10 from UART ?
{
           PIN_setOutputValue(hLedPins, Board_LED1, 1);
           OPT3001();   // sensor read 
}

I am refer

according to svendbt's sample code , I get some messages:

and I also find this function seems not to working:

void UART_enqueueMsg(uint16_t data){
          uartEvt_t *pMsg;

         // Create dynamic pointer to message
          if (pMsg = ICall_malloc(sizeof(uartEvt_t))){
                   pMsg->event = UART_EVT;
                   pMsg->data = data;

        // Enqueue the message.
           Util_enqueueMsg(appMsgQueue, sem, (uint8*)pMsg);
      }
}

does someone knows what's happen , Thank you.
