How is multiple pair possible?

[JoonDong]

I'm using ANSC example, pca10028, iphon5s and iphon4s.

I confirmed #define DEVICE_MANAGER_MAX_BONDS 7.

But pca10028 cannot pair with iphone5s after paired with iphone4s.

Likewise, it cannot pair with iphone4s after paired with iphone5s.

Each pairing is well done.

Modifying DEVICE_MANAGER_APP_CONTEXT_SIZE is the same.

Not sure which SDK version you are using. But the ANCS example in newer SDK's will have whitelisting enabled by default. This meanse the peripheral will ignore connection/scan requests from unknown peers (not in the bond table). It's possible to disable the whitelist by doing a long push on button 2. See here for details about the buttons.
