NRF5函数pm_peers_delete用于从设备的永久存储器中删除一个或多个已配对的对等设备。
语法:
```c
ret_code_t pm_peers_delete(pm_peer_id_t const * p_peer_id, uint32_t peer_cnt)
```
参数:
- `p_peer_id`:要删除的对等设备的ID数组。
- `peer_cnt`:要删除的对等设备的数量。
返回值:
- `NRF_SUCCESS`:操作成功完成。
- `NRF_ERROR_INVALID_PARAM`:无效的参数。
- `NRF_ERROR_NOT_FOUND`:未找到指定的对等设备。
- `NRF_ERROR_BUSY`:蓝牙协议栈正忙,无法执行此操作。
- `NRF_ERROR_INTERNAL`:发生内部错误。
示例:
```c
pm_peer_id_t peer_ids[] = {0, 1};
uint32_t peer_cnt = 2;
ret_code_t err_code = pm_peers_delete(peer_ids, peer_cnt);
if (err_code != NRF_SUCCESS) {
// 处理错误
}
```

NRF5 pm_peers_delete
NRF5 pm_peers_delete is a function in the Nordic SoftDevice that is used to delete a peer device from the peer manager. The peer manager is a module in the SoftDevice that manages the bonds with other Bluetooth devices.
When a device is bonded with another device, a bond is created that allows the devices to securely communicate with each other. The peer manager is responsible for managing these bonds and ensuring that the devices can reconnect with each other in the future.
The pm_peers_delete function is used to delete a bond between two devices. This can be useful if a device is lost or stolen, or if a user wants to remove a device from their trusted list.
To use the pm_peers_delete function, the device must first be connected to the peer manager. Once connected, the function can be called with the ID of the peer device to be deleted. The SoftDevice will then remove the bond between the two devices and update its internal database.
Overall, the pm_peers_delete function is an important tool for managing Bluetooth connections and ensuring that devices can connect securely and reliably.
请详细说明NRF5 SDK中的pm_peers_delete
在NRF5 SDK中,pm_peers_delete是一个用于删除连接配对信息的函数。在蓝牙连接过程中,设备之间需要进行配对才能进行数据传输。配对过程会生成一些信息,包括加密密钥和连接参数等。这些信息会被存储在设备的非易失性存储器中,以便在设备重新连接时使用。
pm_peers_delete函数是用于删除设备存储的配对信息。在某些情况下,比如设备被重置或者需要清除配对信息时,就需要使用该函数。使用该函数可以将设备中存储的所有配对信息都删除,包括加密密钥和连接参数等。
使用该函数需要提供一个参数,即要删除配对信息的设备ID。该设备ID是在进行配对时生成的,每个设备都有一个唯一的设备ID。如果要删除所有设备的配对信息,则需要调用pm_peers_delete_all函数。
需要注意的是,删除配对信息可能会导致设备之间无法进行连接和数据传输。因此,在使用该函数之前,需要确保已经备份了重要的配对信息。
