NCS bonding and skip service discovery

[db_lw]

Hello,

I added bonding to my BLE central device so I can re-establish known connections very fast. The bonding of the devices works fine but additionally I would like the central to connect to unbonded devices then bond and do service discovery. The next time the now bonded device should skip the service discovery and use the known handles.

Is there an easy way to achieve the described behaviour with NCS or at least a way?

Thanks in advance.

nRF Connect SDK: 1.5.1

Hi,

I don't see any Kconfig for this, but the application has control over when it wants to do a service discovery. I will look into what's the best way to achieve this.

Thank you for the reply.

Ok, good to know, so I'm not missing any Kconfig options.

That would be very nice!

I guess something like this could work: After doing a service discovery once I store the handles of the characteristics together with the peer address.
But this wouldn't be a very efficient way if most devices use the same service.
