pstorage_store return error code :15

[Jaro_BLE]

hi, everyone!

I have a question for pstorage, when i use pstorage_store,it was failed, return error code :15 how to solve it. Below is my code

void custom_flash_init(void)
{  
    uint32_t retval;
	pstorage_handle_t       base_handle;
	pstorage_module_param_t param;
				
	param.block_size  = 1024;
	param.block_count = 1;
	param.cb          = flash_cb_handler;
	
    retval = pstorage_init();			
	if(retval == NRF_SUCCESS)
		SEGGER_RTT_printf(0,"------pstorage init success:%d ------ \r\n", retval);
	else
		SEGGER_RTT_printf(0,"------pstorage init failed:%d ------ \r\n", retval);
	
	retval = pstorage_register(&param, &base_handle);
	if (retval == NRF_SUCCESS)
		SEGGER_RTT_printf(0,"------Registration successful.------ \r\n"); 
	else
		SEGGER_RTT_printf(0,"------Failed to register, take corrective action.------ \r\n");
}

enter code here

pstorage_handle_t dest_block_id;

uint8_t test_buf[8] = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08};

uint8_t read_buf[8];

pstorage_store(&dest_block_id, test_buf, 8, 0);  
pstorage_load( read_buf, &dest_block_id, 8, 0);

It looks like you call pstorage_load() right after pstorage_store() without waiting for the callback with a result of the store operation? I.e. you are trying to execute a pstorage operation while another pstorage operation is already pending. Can you try to put a delay between the two functions, preferably implement a way to ensure that pstorage_load() is not called before a callback from the store operation?

Hi Martin Børs-Lind .Thank you for your answer. i have found the problem with my code, when i annotations the device_manager_init(erase_bonds), its working properly. So i don't unserstand what's relationship with its.

pstorage should only be initialized once, and it is being initialized by the device manager. So you need to remove pstorage init from your custom_flash_init() function when you use the device manager.
