Hai
i am able to store one array in flash memmory of nrf51822. but i need to save more than one set of data into flash and retrieve it separately. how can i save more than one set of data in pstorage. actually i need to store the mac address of all device connecting to the device. and i need to check whether the mac address of the device in the flash when a new connection is requested.
here is my code and i am using mbed to program.
#include "mbed.h"
#include "pstorage.h"
#include "nrf_error.h"
uint8_t source_data[4] = {0x0a,0x0b,0x0c,0x0d};
uint8_t dest_data[4];
static void cb_handler(pstorage_handle_t * handle,
uint8_t op_code,
uint32_t result,
uint8_t * p_data,
uint32_t data_len)
{
// printf("Callback handler successful\r\n");
switch(op_code) {
case PSTORAGE_CLEAR_OP_CODE:
if (result == NRF_SUCCESS) {
// printf("Clear operation successful in Callback\r\n");
} else {
// printf("Clear operation failed in Callback\r\n");
}
break;
case PSTORAGE_LOAD_OP_CODE:
if (result == NRF_SUCCESS) {
// printf("Load operation successful in Callback\r\n");
} else {
// printf("Load operation failed in Callback\r\n");
}
break;
case PSTORAGE_STORE_OP_CODE:
if (result == NRF_SUCCESS) {//
// printf("Store operation successful in Callback\r\n");
} else {
// printf("Store operation failed in Callback\r\n");
}
break;
}
}
int main() {
uint32_t retval;
pstorage_handle_t handle;
retval = pstorage_init();
if(retval == NRF_SUCCESS)
{
//printf("initialization successfull\n\r");
pstorage_module_param_t param;
param.block_size = 20;
param.block_count = 1;
param.cb = cb_handler;
retval = pstorage_register(¶m, &handle);
if (retval == NRF_SUCCESS)
{
//printf("Registration successful.\n\r");
//printf("Module id: %u , block: %u \r\n", handle.module_id, handle.block_id);
}
else
{
// Failed to register, take corrective action.
}
}
else
{
//printf("initialization fail\n\r");
}
retval = pstorage_store(&handle, source_data,4,0);
if (retval == NRF_SUCCESS)
{
printf("Store successfully requested. Wait for operation result.\n\r");
}
else
{
printf("Failed to request store, take corrective action.\n\r");
}
wait(1);
retval = pstorage_load(dest_data, &handle, 4,0);
if (retval == NRF_SUCCESS)
{
printf("Load successful. Consume data.\n\r");
printf("STORE: %02x:%02x:%02x:%02x\r\n", source_data[0], source_data[1],source_data[2],source_data[3]);
printf("LOAD: %02x:%02x:%02x:%02x\r\n\n\n\n", dest_data[0], dest_data[1],dest_data[2],dest_data[3]);
}
else
{
// printf("Failed to load, take corrective action.\n\r");
}
}
