HRM1017 Serial port delay and loss

Hello,

Loss of rare data in serial communication (Rx) and the delay (Tx) may occur.

ch1 Rx,ch2 Tx

baudrate:19200

TxData:14byte

received use https://developer.mbed.org/users/KentaShimizu/code/BufferSerial/

Transmission use https://developer.mbed.org/handbook/Serial

code

--------------------

Serial StdUart(P0_9,P0_11);

void UartTxData(unsigned char *InData)

{

char TxData[BLE_DATA_LEN + 2 + 1] = {0};

TxData[0] = UART_PREFIX_1ST_BYTE;

TxData[1] = UART_PREFIX_2ND_BYTE;

memcpy(&TxData[2],InData, BLE_DATA_LEN);

StdUart.printf("%c%c%c%c%c%c%c%c%c%c%c%c%c%c",TxData[0] ,TxData[1],TxData[2],TxData[3],TxData[4],TxData[5],TxData[6],TxData[7],TxData[8],TxData[9],TxData[10],TxData[11],TxData[12],TxData[13]);

}

--------------------

I want to avoid the loss and delay of data, Is there a way?

Is there a problem with the transmission method?

Or it is transmitted and received at the same time there is no problem?

Regards,
