Device manager with bonds in RAM

[Nikita]

I'm using SDK 6 + S110 v7.

Is it possible to use device manager to perform bonding but don't write bond information persistently in flash?

With old bond manager I could do this by removing ble_bondmngr_bonded_centrals_store() from BLE_GAP_EVT_DISCONNECTED event in on_ble_evt() so it won't store bonds in flash. So how can I do this with new SDK?

This should be possible.

In for example ble_app_hrs_c. Can't you just remove device_context_store() in dm_ble_evt_handler(), under case BLE_GAP_EVT_DISCONNECTED: and case BLE_GAP_EVT_AUTH_STATUS:?

Or is there something I have overlooked?

I can put in a request to improve this if you want me to.

That would be great. I think it'll be convenient to add flag to dm_init_param_t structure that will be passed to dm_init() function like this:

typedef struct
{
    bool clear_persistent_data;      /**< Set to true in case the module should clear all persistent data. */
    bool no_persistent_data_in_nvm;  /**< Set to true in case the module shouldn't store persistent data in non-volatile memory. */
} dm_init_param_t;

And inside device manager skip all pstorage operations if no_persistent_data_in_nvm flag is set.
