在添加了lwgps后，测试用例使用不了，有同学弄过这一块吗？我的怎么就是不行呢…. 我用的是和芯星通的GPS芯片。 //***************************************************************************** // file : lwgps2rtt.c // porting lwgps to rt-thread // // Change Logs: // Date Author Note // 2020/09/05 Cheney First draft version // 2020/09/13 Cheney 1.

lwgps_process(&h_lwgps, &ch, 1); 一个字节字符就想解析出来信息？

我也看到了，他是一个字节，具体的程序解析源码我没有去看，我现在修改好了。

对lwgps2rtt.c文件做了如下修改，大家可以对照，可以正确的解析GPS数据了。
