Hi,
I'm trying to use the pstorage on a central device.
An event of BLE_GAP_EVT_ADV_REPORT is called by discovering some ble devices while a central device is scanning.
Now, when this event was occured, i call a pstorage_store method in it.
But, this way is not working as expected.
Below, this is my code:
・ Initialize pstorage
static void my_pstorage_init(void) {
uint32_t err_code;
pstorage_module_param_t param;
// Initialize pstorage
err_code = pstorage_init();
APP_ERROR_CHECK(err_code);
param.block_size = 16;
param.block_count = 10;
param.cb = pstorage_cb_handler;
err_code = pstorage_register(¶m, &pstorage_handle);
APP_ERROR_CHECK(err_code);
pstorage_wait_flag = 1;
pstorage_wait_handle = pstorage_handle.block_id;
pstorage_block_identifier_get(&pstorage_handle, 0, &pstorage_block_handle);
pstorage_clear(&pstorage_block_handle, 16);
while(pstorage_wait_flag) {
power_manage();
}
}
・ Test saving data method
static void test_pstorage(void) {
uint8_t source_data[16] = {0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F};
uint8_t dest_data[16] = {0};
pstorage_block_identifier_get(&pstorage_handle, 0, &pstorage_block_handle);
pstorage_wait_flag = 1;
pstorage_wait_handle = pstorage_block_handle.block_id;
pstorage_clear(&pstorage_block_handle, 16);
while(pstorage_wait_flag) {
power_manage();
}
pstorage_block_identifier_get(&pstorage_handle, 0, &pstorage_block_handle);
pstorage_wait_flag = 1;
pstorage_wait_handle = pstorage_block_handle.block_id;
pstorage_store(&pstorage_block_handle, source_data, 16, 0);
while(pstorage_wait_flag) {
power_manage();
}
pstorage_block_identifier_get(&pstorage_handle, 0, &pstorage_block_handle);
pstorage_wait_flag = 1;
pstorage_wait_handle = pstorage_block_handle.block_id;
pstorage_load(dest_data, &pstorage_block_handle, 16, 0);
printf("dest_data size : %d \r\n", sizeof(dest_data));
uint16_t i;
for (i = 0; i < sizeof(dest_data); i++) {
printf("%02x ", dest_data[i]);
}
printf("\r\n");
}
・ Call the test_pstorage method in ble eventing
static void on_ble_central_evt(ble_evt_t * p_ble_evt) {
uint32_t err_code;
const ble_gap_evt_t * p_gap_evt = &p_ble_evt->evt.gap_evt;
switch (p_ble_evt->header.evt_id) {
case BLE_GAP_EVT_ADV_REPORT: {
// Initialize advertisement report for parsing.
ble_gap_addr_t pa = p_gap_evt->params.adv_report.peer_addr;
int8_t rssi = p_gap_evt->params.adv_report.rssi;
test_pstorage();
}
case BLE_GAP_EVT_TIMEOUT:
// ...
case BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST:
/ ...
case BLE_GAP_EVT_DISCONNECTED:
/ ...
default:
break;
}
}
- My environment version
- nRF51 SDK 9.0.0 (using softdevice : s130)
- keil v5.15
- nRFgo Studio 1.21.0.2
Actually, i want to a output "00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f", but don't show results in console at all.
However the test_pstorage method is called in main method at once only, and it was success.
So, my questions are
- How can i store the some data to pstorage while doing ble events ?
- Why will be success calling the method at once only ?
I thank you for reading it through.
