Ok, thanks for letting us know. I have reported it internally.

thanks. I think I done with this now. My post was just to inform you, that there is an example, that might be missleading.

Hi Torsten,

I can understand your point about the overhead. Much of it is of course comes from the fact that it needs to be a generic solution and support features that won't be needed for every application (concurrent GAP roles, Service changed, GATT caching, etc).

Maybe it could be helpful to take a look at the old device manager implementation in SDK 11 as well, even though it's not supporting new features such as LESC. It has a simpler design.

Hi Vidar,

an example, that implements bonding without the peer_manager would be great, as the peer_manager has some limitations and overhead that is not suitable in every situation.

best regards,

Torsten

Hello Torsten,

I haven't noticed that this example attempted to support bonding without the peer manager. Unfortunately, the implementation is incomplete. It does for instance not store data such as LTK and CCCDs, which is supposed to be kept across connections. To support bonding, I would strongly recommend you use the peer manager or at least use it as a reference if you are creating your own.

Best regards,

Vidar
