Z-Wave 800：SE 固件升级

基于 EFR32ZG23 的Z-Wave 800 系列 ，集成了安全运行引擎 (SE) 。Z-Wave 800 系列包含出厂安装的 SE 固件。Silicon Labs 将定期发布新版本的 SE 固件以修复错误和修补漏洞，这可能需要对生产线上的设备或已安装的设备进行更新。强烈建议在EFR32ZG23系列设备上安装最新的 SE 固件以支持所需的安全运行功能。

如何检查设备上的 SE 固件版本

可以使用 Simplicity Studio 或 Simplicity Commander 读取设备的当前 SE 固件版本。

>commander.exe security status -d EFR32ZG23A010F512GM40 -s 261000352
SE Firmware version : 2.1.7
Serial number       : 0000000000000000ccccccfffef8d1c4
Debug lock          : Disabled
Device erase        : Enabled
Secure debug unlock : Disabled
Tamper status       : OK
Secure boot         : Disabled
Boot status         : 0x20 - OK
DONE

 如果无法读取 SE 固件版本，请尝试使用 Simplicity Commander 恢复设备。

>commander.exe device recover -d EFR32ZG23A010F512GM40 -s 261000352
