pm_whitelist_get can't get whitelisted peers after system reset

[jloliveira]

Good afternoon,

In my peripheral application (SDK15 and Softdevice6.0.0) I can have several bonded central peers but only 1 can be selected on demand for the whitelist, by recurring to pm_whitelist_set() and pm_device_identities_list_set() to also preserve the peer address identity. Yet, when I reset the peripheral device I can't retrieve the peer in the whitelist with pm_whitelist_get() as it is always empty - it seems it can't recover it from flash or it is not saved at all when calling pm_whitelist_set().

Is there something I'm doing wrong when saving the peer in the whitelist? Do you have any solution for this?

Thank you,

João Oliveira

Hi,

pm_whitelist_set() is not used to store Peers in the bond table. It is used to tell the SD which whitelist to use, it eventually calls sd_ble_gap_whitelist_set which is used to set the active whitelist in the Softdevice.

To fetch the whitelist from the peer manager, look at the ble_peripheral\ble_app_hids_keyboard project. see the peer_list_get function in main.c.

Dear Runar,

Thank you for your reply.

The peer_list_get function retrieves all bonded peers and I would like to retrieve from flash only the peers in the whitelist, i.e., only the ones added to the whitelist through the pm_whitelist_set function. Is there any function or means for that?

Thank you,

João

Not long term. Normally we would retrieve the whitelist from the peer manager / gatt cache manager. If you are only using a subset of these you will have to store them somewhere in flash around the same time as you send them to the SD iwh pm_whitelist_set function. It is not possible to retrieve this after a reset as it is stored in the SD ram.

Thank you Runar, just created an FDS record for the whitelisted peers and it is working great.

How can I close the case?
