nrf51822 can't sleep

[arthur]

my project can't goto sysoff mode, (desktop2)( project based on mouse demo)

m_prw_mgmt_set_sysoff_timeout(DEFAULT_BTLE_INACTIVITY_DISCONNECT_PERIOD);//can't sleep here!

my code.DEFAULT_BTLE_INACTIVITY_DISCONNECT_PERIOD //10s The default: 1hour

when timeout,system goto off,

m_coms_ble_wakeup_prepare

goto↓

m_coms_ble_disable

goto↓

/ /Save bond information to flash
    err_code = ble_bondmngr_bonded_centrals_store();
    APP_ERROR_CHECK(err_code);

goto↓

// Save System Attributes, if changed.
if(sys_attr_changed())//==1

M_cmd_queue.conut change "1" from "0"

：goto↓

pstorage_access_wait()

do
    {
             app_sched_execute();        
               err_code = pstorage_access_status_get(&count);
        if (err_code != NRF_SUCCESS)
        {
            return err_code;
        }        
    }
    while(count != 0);//***can't pass***

my steps:

1， download the hex 2， power on mouse 3， try to connect 4， not found any host
5， connect timeout 6， error

： System Attributes in RAM is different from that in flash.

is this ↑cause the proble? how to fix it?

I am not sure if your problem is with the system off power management or with the pstorage module. This specific example has a prepare routine before entering systemoff, which is then done based on which protocol the example is running (proprietary or BLE).

Also, please see if you have any asserts occurring in your application by enabling the assert-handler: devzone.nordicsemi.com/.../
