pstorage data is cleared after DFU

[roy756456625]

Hi: I reference rate meter program： “nRF5_SDK_11.0.0_89a8197\examples\ble_peripheral\ble_app_hrs\pca10040\s132_with_dfu”. After function "device_manager_init"，I handle a custom pstorage.

void nonvolatile_storage_init(void) { ret_code_t err_code; pstorage_module_param_t param;

err_code = pstorage_init(); if (NRF_SUCCESS != err_code) {

}

param.block_size = NONVOLATILE_BLOCK_SIZE; // 24
param.block_count = NONVOLATILE_BLOCK_COUNT; // 3
param.cb = nonvolatile_cb_handler;

err_code = pstorage_register(&param, &nonvolatile_handle); if (NRF_SUCCESS != err_code) {

} } And it is work ok.It can save my data,but after DFU,data in this area was cleared.But this is not the result I wanted.So can you help me,tell me how to deal with it. Thank you very mach!

Hi

Please look at the information given on this thread, specifically the last part of my answer that mentions how to prevent the DFU from overwrite application data.

Hi

infocenter.nordicsemi.com/index.jsp " Preserving application data" Simply change this value,also can't save application data(pstorage data). It's have note that there are other points?

Also can't help me. I use nRF52832(PCA10040)

Can you tell me how to do in the examples ble_app_hrs(s132_with_dfu)?

Thank you !
