使用hcitool是没有问题的，就是无法理解的是使用bluetoothctl软件进入交互界面，那些命令毫无反应。

我的芯片是瑞芯微 RV1103/RV1106，对应的SDK里面的交叉编译器的C库是基于uClibc，在bluez5_utils: not available with uClibc 可以了解到，Bluez5.27以后的版本是引入了glibc的wordexp模块的（对应的wordexp.c, wordexp.h）而uClibc是没有实现这个wordexp模块的。
好在bluez5源码里面自带了一个wordexp.h文件，里面的两个函数是空的没有实现（使得可以编译过去不报错），
#ifndef _WORDEXP_H_
#define _WORDEXP_H_
#define WRDE_NOCMD 0
typedef struct {
size_t we_wordc;
char **we_wordv;
size_t we_offs;
} wordexp_t;
static inline int wordexp(const char *c, wordexp_t *w, int _i)
{
return -1;
}
static inline void wordfree(wordexp_t *__wordexp)
{
}
#endif目前评估可能是由于uClibc这个C库功能支持不完整导致 bluetoothctl软件的交互命令没有反应。
