How to correct use dm_device_delete_all

[Vyacheslav Lebets]

Hi All ! I was read many posts about this function and do not understand how to check if all data is deleted.

In my situation I do:

1. Start advertising for bonded divices

2. Unexpectedly in advertising state, I need create a new pairing and I call:

   • dm_device_delete_all - for deleting information about all bonded peers
   • sd_ble_gap_adv_start - start advertising whith new params.

The dm_device_delete_all return NRF_SUCCESS, but data not clear.

Is the true to check

DM_CLEAR_OPERATION_ID == p_event->event_id

in device_manager_evt_handler(...) or is there another solution ?

Thanks!!!

In device_manager.h, above declaration of function dm_device_delete_all is writed: "If this API returns NRF_SUCCESS, DM_EVT_DEVICE_CONTEXT_DELETED event is notified to the application for each device that is deleted from the data base"

I simply add code:

case DM_EVT_DEVICE_CONTEXT_DELETED:

in device_manager_evt_handler(...) and hook clearing result.

Attension: if DM "white list" is empy, that event is not occur.

Hi Vyacheslav, I need the same solution but my DM "white list" is empty, that event is not occur. How can I get the notification of the DM data deleted? Gino Lin

Hi, Gino. Sory for my question, but what and which data you need to delete if white list is empty?

Hi Vyacheslav, I want to delete all bonded data to start a new pairing. By the way, is there any example for deleting current bonded data? Thanks.
