[+ 2.9.1] CoreStation40 Set security key for OSDP devices.
The device identifier can send the identifier of the master device or the identifier of the slave device, but the operation is slightly different.
If key information is sent with the identifier of the master device as a device identifier, the master device will replace its primary key value with a new set key value.
At this time, OSDP slave devices should not be connected, and if there are connected devices, BS_SDK_ERROR_FAIL_MASTER_SET_KEY error may occur.
The master device sends a new key to process secure communication each time the OSDP device is connected.
Sending the OSDP slave device identifier as the device identifier, the master device sends the key it is holding to the slave device.
In other words, this command instructs the master device to send the key it holds to the specified OSDP device. Therefore, no separate key delivery is required in this case. (=NULL)

• [In] context : Context
• [In] masterOrSlaveId : Device Identifier
• [In] key : Security key information structure pointer

If successfully done, BS_SDK_SUCCESS will be returned. If there is an error, the corresponding error code will be returned.
