How to store the received data from ble nus into flash memory

[ps_anu]

Hi...  I have merged the ble_app_uart and fstorge example .  I am storing the received data in a variable and passing in flash using nrf_fstorage_write command . I am getting nrf_breakpoint while I am sending the data from ble_app. Why ? What is the issue .. When I tried to send the data from ble_app only I am getting this error.  Please anyone suggest me 

Thanks&Regards

Could you upload your code (main.c) to this ticket? Then I can take a look at it and figure out what might cause the unwanted behavior. Click on Insert→Insert image/video/file→From→File Upload, then find main.c and click Ok.

Hi, I am also facing the same issue. The data is being received in p_data, but I am unable to write the received data to flash memory. I have tried using fds and fstorage. PFA the main.c file below. This is a snippet of the ble_data_handler and int_main(). 

 

char data[100];
uint32_t address=0x60000;
static void nus_data_handler(ble_nus_evt_t * p_evt)
{
    //ret_code_t err_code;
    app_uart_flush();
    if (p_evt->type == BLE_NUS_EVT_RX_DATA && p_evt->params.rx_data.length>0)
    {
        uint32_t err_code;

        NRF_LOG_DEBUG("Received data from BLE NUS. Writing data on UART.");
        //NRF_LOG_HEXDUMP_DEBUG(p_evt->params.rx_data.p_data, p_evt->params.rx_data.length);
        for (uint32_t i = 0; i < p_evt->params.rx_data.length; i++)
        {
            do
            {
                data[i]=p_evt->params.rx_data.p_data[i];
                err_code = nrf_fstorage_write(&fstorage, address, p_evt->params.rx_data.p_data[i], p_evt->params.rx_data.length, NULL);
                //APP_ERROR_CHECK(err_code);
                address++;
                //err_code = app_uart_put(p_evt->params.rx_data.p_data[i]);
                //if ((err_code != NRF_SUCCESS) && (err_code != NRF_ERROR_BUSY))
                //{
                //    NRF_LOG_ERROR("Failed receiving NUS message. Error 0x%x. ", err_code);
                //    APP_ERROR_CHECK(err_code);
                //}
            } while (err_code == NRF_ERROR_BUSY);
        }
        //if (p_evt->params.rx_data.p_data[p_evt->params.rx_data.length - 1] == '\r')
        //{
        //    while (app_uart_put('\n') == NRF_ERROR_BUSY);
        //}
    }
    printf("The length of data is: %d\n\r",p_evt->params.rx_data.length);
    ble_data_receive=true;
    printf("BLE Data received and bool changed to true\n\r");
}
