pstorage is always pending and advertisement does not resume

[Gilson]

Hello Guys,

Everything was working fine with my nRF51822 device but all of the sudden the hardware started not to resume advertisements upon disconnecting from the host.

I debugged the issue down to the following function:

static void advertising_start(void)
{
    uint32_t err_code;
    uint32_t count;

    // Verify if there is any flash access pending, if yes delay starting advertising until 
    // it's complete.
    err_code = pstorage_access_status_get(&count);
    APP_ERROR_CHECK(err_code);
    
    if (count != 0)                <==== COUNT IS ALWAYS RETURNING NON-ZERO
    {
        m_memory_access_in_progress = true;
        return;
    }
    
    start_advertisement_timeout = false;
    err_code = sd_ble_gap_adv_start(&m_adv_params);
    APP_ERROR_CHECK(err_code);

}

So the code starts fine I see advertisements then I pair with the host as a mouse. I tell the host to disconnect and the nRF51822 should resume advertisements but something is causing Flash Access to be in a pending state because count is returning non-zero. why? what could it be?

pstorage_sys_event_handler(uint32_t sys_evt) is getting triggered but m_cmd_queue.flash_access is false. m_cmd_queue.count is equals 4.

Trying to understand this so I can fix the problem.

Thanks,

The proposed solution is still not fixing the bug - when the device is bonded with the phone and disconnect occurs - it really never starts advertisement again.
