Enable UART in BLE CC2541 stack

Hi Yikai Chen,
It Worked. Thanks a lot. You have been always helpful.

You are welcome.

Hi Yikai Chen,

I am facing problem in uart reception in BLE stack as explained. when i send 20bytes of data through serial port to module, first 2 or 3 bytes are only received when "uart0RxCb()" called for the first time. later it is called again and rest of the bytes are received. I mean to say i am not able to get sigle packet of 20bytes but getting them in chunks. Can you please suggest some suggestions? I am using simplebleperipheral example.

uint8 temp_len =0; //defined temporary variable

void uart0RxCb( uint8 port, uint8 event )
{
  uint8  ch;
  while (Hal_UART_RxBufLen(port))
  {
    // Read one byte from UART to ch
    HalUARTRead (port, &ch, 1);
    temp_len++;
  }
  temp_len =0;
}

You can only collect them from separate chunks in process it in your application.

I need to transfer the received data to mobile. Can you please suggest some idea how can i send data correctly so that it is not interpreted wrongly by mobile app? I need to transfer around 512kb data received from serial port(external MCU) and transmit to mobile app.

I am thinking to use large buffer to store the received data and later send them 20-20 bytes. But this will reduce the data rate much.

No better idea other than use a buffer to store the received data and later send them 20-20 bytes.

Ok i will try to do the same and check how it works.
Thanks

You are welcome.
