Hello everybody,
I'm trying to use pstorage module but it seems that the example_cb_handler function is never called when I try to store data.
I noticed similar issues in the forum and read pstorage documentation but It still doesn't work...
static void example_cb_handler(pstorage_handle_t * handle,
uint8_t op_code,
uint32_t result,
uint8_t * p_data,
uint32_t data_len)
{
nrf_gpio_pin_set(LED_4); // Clear Led if example_cb_handler called
if(handle->block_id == pstorage_wait_handle) { pstorage_wait_flag = 0; } //If we are waiting for this callback, clear the wait flag.
}
static void pstorage_test_store_and_update(uint8_t*dest_data_0)
{
pstorage_handle_t handle;
pstorage_handle_t block_0_handle;
pstorage_module_param_t param;
uint8_t source_data_0[16] = {0x00, 0x01, 0x31, 0x20, 0x22, 0x05, 0x06, 0x21, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F};
uint32_t retval;
retval = pstorage_init();
if(retval != NRF_SUCCESS)
{
nrf_gpio_pin_set(LED_4);
}
param.block_size = 16; //Select block size of 16 bytes
param.block_count = 10; //Select 10 blocks, total of 160 bytes
param.cb = example_cb_handler; //Set the pstorage callback handler
retval = pstorage_register(¶m, &handle);
if(retval != NRF_SUCCESS)
{
nrf_gpio_pin_set(LED_4);
}
pstorage_block_identifier_get(&handle, 0, &block_0_handle);
pstorage_wait_handle = block_0_handle.block_id; //Specify which pstorage handle to wait for
pstorage_wait_flag = 1;
pstorage_store(&block_0_handle, source_data_0, 16, 0); //Write to flash, only one block is allowed for each pstorage_store command
while(pstorage_wait_flag) { power_manage(); }
pstorage_load(dest_data_0, &block_0_handle, 16, 0); //Read from flash, only one block is allowed for each pstorage_load command
}
int main(void)
{
uint8_t dest_data_0[16];
. . .
pstorage_test_store_and_update(dest_data_0);
for (;;)
{
power_manage();
ble_attempt_to_send(dest_data_0, 16);
}
}
I didn't forget to do this part :
static void sys_evt_dispatch(uint32_t sys_evt)
{
pstorage_sys_event_handler(sys_evt);
}
static void ble_stack_init(void)
{
uint32_t err_code;
// Initialize SoftDevice.
SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION, false);
// Enable BLE stack
ble_enable_params_t ble_enable_params;
memset(&ble_enable_params, 0, sizeof(ble_enable_params));
ble_enable_params.gatts_enable_params.service_changed = IS_SRVC_CHANGED_CHARACT_PRESENT;
err_code = sd_ble_enable(&ble_enable_params);
APP_ERROR_CHECK(err_code);
// Subscribe for BLE events.
err_code = softdevice_ble_evt_handler_set(ble_evt_dispatch);
APP_ERROR_CHECK(err_code);
// Register with the SoftDevice handler module for BLE events.
err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
APP_ERROR_CHECK(err_code);
}
My Led is never off so I assume the handle function is never called when I store the data to the flash... I'd be really grateful is somebody can help me !
Regards, Damien
