wait_for_queue() hangs on re-init of DFU service

The problem is mainly due to the inability to re-init the flash whilst you have pending flash operations (from peer manager and DFU init). They need to be handled before attempting a re-init. Also if you are using freertos you need to modify:

app_timer_create()

Here is the fix that seems to be working for me:

static uint8_t is_flash_busy(void) {

uint32_t count;

fs_queued_op_count_get(&count);

return (count!=0);}

static void pre_ble_reinit(void) {

while(is_flash_busy())
 {
    while (pdFALSE == xSemaphoreTake(m_ble_event_ready, portMAX_DELAY));

    intern_softdevice_events_execute();
 }}

Unfortunately I'm on a tight timeline, I'll have to come up with a work-around or a fix.

@ypearson: In SDK v12.x.0 the DFU Service uses a rather inefficient approach(writing data to the bootloader settings page) to signal the bootloader to stay in bootloader mode after the application performs a soft-reset. This approach was abandoned in SDK v13.0.0 where we simply write to the GPREGRET register, perform a soft-reset and then check the GPREGRET register upon entering the bootloader. Thus, I recommend moving to SDK 13 or backporting this feature from SDK v13.

Hi, which SDK version are you using?
