How to delete host bonds while keeping peripheral bonds

[AlbertBao]

Hi,

I'm using nrf52832 as host and peripheral concurrently, with soft device s132. I know that peer manager can handle both host and peripheral.

I now have a need to remove the bonds of host, at the same time I want to keep the bond data of peripheral.

So how can I get a list of bond device and determine which one belongs to host and which one belongs to peripheral?

I tried to search the forum but did not find related info.

Thank you.

Hi,

The GAP role is included as a part of the bonding information. It should be possible to use the pm_peer_count() and pm_peer_data_load() API exposed in peer_manager.h to first find the number of bonds, then retrieve the bonding information to find the GAP role of a particular bond.

You can probably do something like this to run through the list of bonds (I have not tested it): 

uint32_t               err_code;
uint32_t               bond_cnt;
pm_peer_data_bonding_t bonding_info;

bond_cnt = pm_peer_count();

for (pm_peer_id_t id=0; id < bond_cnt; id++)
{
    err_code = pm_peer_data_bonding_load(id, &bonding_info)
    APP_ERROR_CHECK(err_code);
    
    if (bonding_info.own_role == BLE_GAP_ROLE_PERIPH)
    {
        //TODO: Bond belongs to GAP peripheral role
    }
    else if (bonding_info.own_role == BLE_GAP_ROLE_CENTRAL)
    {
        //
    }  

}

Hi Vidar,

Thank you for the quick reply, I'll try to see if it works.

Thank you.
