-**功能描述：一个无线姿态追踪模块，可以追踪姿态。可以用于全身动作捕捉也可以用于人体步态追踪, GeekTrack实际是GeekMotion阉割屏幕减少尺寸的版本，目的是为了方便固定在身体上，用于姿态追踪**
+## 一、功能描述：
 
-**GeekMotion:** https://github.com/Logzhan/GeekMoton
-
-状态：PCB已经打样测试完成，设备WIFI正常，信号对比PCB天线弱一些。IMU、气压计读取数据正常、SD卡识别正常。

-**更新日志：**
+注意：命令行被log覆盖的时候按下回车即可。
 
-**2022-09-03 :**    1）上传第一版原理图和PCB图
+## 二、使用方法
 
+WIFI的配置(通过命令行)：
 
+```shell
+# 命令行设置WIFI账号和密码
+set_wifi_cfg "your wifi ssid" "your wifi password"
+# 设置完成后重启生效
+reboot
+```
+
+配置设备索引：可以用数字表示设备的索引，数字可以为0~65536
+
+```shell
+set_dev_idx  "device_type_num" 
+```
+
+设备传感器信息的发送，默认UDP端口9000：

+3. 删除GeekTrack无用的关于lvgl部分
+4. 删除无用的lvgl仿真器
+5. 增加NVS存储获取设备索引信息(Idx,可以描述设备0~n)
+6. UDP发送增加Idx识别信息
+7. 增加NVS设置Idx
+
+**2022-09-25:**  增加NVS设置WIFI ssid和WIFI 密码功能
