Yeah that one only.

I'll try this.

Hi.

Do you mean the example found in the folder: <InstallFolder>\examples\peripheral\uart ?

You can use the API function app_uart_get() to get the data from UART and store it in a struct for example.

/**@brief Function for getting a byte from the UART.
 *
 * @details This function will get the next byte from the RX buffer. If the RX buffer is empty
 *          an error code will be returned and the app_uart module will generate an event upon
 *          reception of the first byte which is added to the RX buffer.
 *
 * @param[out] p_byte    Pointer to an address where next byte received on the UART will be copied.
 *
 * @retval NRF_SUCCESS          If a byte has been received and pushed to the pointer provided.
 * @retval NRF_ERROR_NOT_FOUND  If no byte is available in the RX buffer of the app_uart module.
 */
uint32_t app_uart_get(uint8_t * p_byte);

Best regards,

Andreas

Thanks for the reply.But i am not using ble_app_uart ,I am using UART(uart_pca1040) which is working fine.Only thing i want is how to store/retrieve received data for processing.

Hi.

If you take a look at the documentation for the UART example (<InstallFolder>\examples\ble_peripheral\ble_app_uart), you can read about handling data received over UART.

Best regards,

Andreas
