Hi Keneth,

After so many times testing, I found that the serial not work if the PC's transmission is fast(10ms probably) or the sending data size is greater than 10 bytes, do you have any ideas for that issue? thank you very much.

From the documentation is says:

/**
 * @brief Function for reading from a serial port.
 *
 * @param p_serial   Serial port instance.
 * @param p_data     Receive buffer pointer.
 * @param size       Receive buffer size.
 * @param p_read     Amount of data actually read from the serial port.
 *                   NULL pointer can be passed.
 * @param timeout_ms Operation timeout, in milliseconds. Pass 0 to operate in
 *                   non blocking mode.
 *
 * @return Standard error code.
 * */
ret_code_t nrf_serial_read(nrf_serial_t const * p_serial,
                           void * p_data,
                           size_t size,
                           size_t * p_read,
                           uint32_t timeout_ms);

Wouldn't timeout_ms=0 do the trick?
