Device manager with bonds in RAM

I would like to do the same thing (bonding without flash usage, keeping data in ram) but this thread is about a very old SDK

I am using sdk 13 with S132 v4.0.2

Is it still possible to do it?

Thanks in advance

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.

I agree with you, it is unfortunate that it requires modification of the library, but I don't see any other way to do it. I can put in a request to improve this if you want me to.

Yes I can, but it's require changes in SDK files that I want to avoid, I want to use one common SDK sources for all projects. And another problem is updating SDK to new version will require to make all changes in SDK anew.

Well in this simple case this problems is insignificantly, but in general this approach to the construction of this project looks bad.

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?
