Hi
I am using the nrf53832 dk.
In the nus example once the data is received from the phone(central) I want to write this data to the flash. I referred to the fstorage example for flash write.
I made the following changes to the nus_data_handler function.
I am able to run the code, but when i send data from my phone(central) to the dk no data is sent and the device gets disconnected and starts advertising again.
static void nus_data_handler(ble_nus_evt_t * p_evt)
{
char wagon[20];//string i added
if (p_evt->type == BLE_NUS_EVT_RX_DATA)
{
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);
strcpy(wagon,p_evt->params.rx_data.p_data);//string copy
for (uint32_t i = 0; i < p_evt->params.rx_data.length; i++)
{
do
{
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);
}
}
//changes i made
ret_code_t rc;
nrf_fstorage_api_t * p_fs_api;
p_fs_api = &nrf_fstorage_sd;
rc = nrf_fstorage_init(&fstorage, p_fs_api, NULL);
APP_ERROR_CHECK(rc);
rc = nrf_fstorage_write(&fstorage, 0x3e000, wagon, strlen(wagon), NULL);
APP_ERROR_CHECK(rc);
}
Is my methodology of writing to flash correct?
If not what changes should i make?
Thanks in advance
