# 如何为GAT562升级 Meshtastic原版和中文固件

\
感谢 MeshCN 社区伙伴的支持，现如今Meshtastic官方已支持 GAT562的固件支持，最新的固件都会发布并同步在<https://github.com/meshtastic/firmware/releases> 的仓库中。

以往的 nRF52840 Meshtastic设备或 GAT562 的固件升级方法有2种方式，

1. USB连接拓展从Github下载后解包出来适合GAT562的`uf2`文件
2. 通过nRF的`DFU App` 蓝牙上传从从Github下载后解包出来适合 GAT562 的`ota.zip`文件

如今 MTools BLE 已支持 GAT562 固件的一键下载和快速的Legacy DFU更新，整个过程大概花费3分钟。
