Using gazell with FDS

Question

In our application we use gazell. We also want to use the flash data storage which uses softdevice. 
 With gazell enabled, we cannot access flash. 
 What is the recommended way to access FDS with gazell?

If you don't plan to have activity when you are doing gazell then switching back and forth between softdevice and gazell is possible. We have an example of switching between them in \examples\multiprotocol\ble_app_gzll. 
 If you want to use softdevice and gazell concurrently, it's more complex as the softdevice blocks access to the radio. And you would need to use timeslot to grant access to the gazell stack. But it's posisble. 
 
 Another option is to use pstorage_nosd.c module from SDK v11 or accessing the flash directly using NVMC peripheral as what we do in \examples\peripheral\flashwrite
