安全数据库如何管理

据我所知，关于BlueNrg-MS设备上绑定的编程手册部分，加密密钥存储在安全数据库中，以便解析地址并加密未来的数据连接。
这一切似乎都按预期工作，但我不清楚如何管理安全数据库随着时间的推移，当许多设备在其生命周期内与设备配对时
有多少不同
结合
设备可以处理安全数据库，以及填充数据库时预期会发生什么？
我知道aci_gap_clear_security_database api，但是因为这会清除所有配对的设备，我想避免调用它
除非需要。

As i understand the programming manual section about bonding on BlueNrg-MS devices, encryption keys are stored in the security database in order to resolve addresses, and encrypt future data connections.
This all seems to work as expected, but it is unclear to me how to manage the security database over time, when a number of devices is expected to pair to the device during its lifetime
How many different
bonding
devices can the security database handle, and what is expected to happen when the database is filled up ?
I am aware of the aci_gap_clear_security_database api, but as this clears all paired devices I would like to avoid calling this
unless needed.

嗨安德斯，
使用BlueNRG-MS，固件版本为7.2c，安全数据库中的最大条目数为12。

当它填满时，旧的条目会被新的条目覆盖。除非你真的想要删除所有条目，否则你不需要调用aci_gap_clear_security_database API。
最好的祝福，

Hi Anders,
with BlueNRG-MS, firmware version 7.2c, the maximum number of entries in the security database is 12.

When it fills up, older entries get overwritten by the new ones.Unless you actually want to delete all entries, you don't need to call the aci_gap_clear_security_database API.
Best regards,

Antonio
