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.
