Can you please edit your question and include your complete project? Zip the ble_app_uart folder and attach it.

What SoftDevice and SDK version are you using? Could you edit your question and upload your complete project so I can test it here?

Hi, thanks for your help. But I still failed in update the data into the flash. I check the return values/error codes of pstorage_block_identifier_get(), pstorage_clear(), and pstorage_update, the return value of these functions are "NRF_SUCCESS". when call the "pstorage_update" it returns "NRF_SUCCESS", when then it reset.

Why are you clearing before updating? Wouldn't this be equivalent of clearing and then storing? You should check the return values/error codes of pstorage_block_identifier_get(), pstorage_clear(), and pstorage_update. Not just pstorage_update(). pstorage_clear() is non-blocking, so when it returns it doesn't mean that the block is cleared. You need to use the event notification handler to know if and when the operation is successful. Please examine the documentation. There are also several questions on devzone explaining this.
