How to distinguish bounded devices by type?

[Mikhail]

SDK13, nRF52. I bounded different devices into nRF52. Some of that is another device on nRF52, another devices- smartfone.

How can I distinguish for delete those devices? I want to delete one of them group. For ex. I want to delete only smartfones.
