python 一句话的事儿你非要用 C 写...
那么你需要:
安装一堆编译环境例如essential啊 cmake啊..然后要安装 linux 头文件.
1. sudo apt install linux-headers
安装蓝牙开发库 里面也有头文件.
2. sudo apt-get install libbluetooth-dev
3. 然后搞一段代码 像下面这样:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/socket.h>
#include <bluetooth/bluetooth.h>
#include <bluetooth/hci.h>
#include <bluetooth/hci_lib.h>
int main(int argc char **argv)
{
inquiry_info *ii = NULL;
int max_rsp num_rsp;
int dev_id sock len flags;
int i;
char addr[19] = { 0 };
char name[248] = { 0 };
dev_id = hci_get_route(NULL);
sock = hci_open_dev( dev_id );
if (dev_id < 0 || sock < 0) {
perror("opening socket");
exit(1);
}
len = 8;
max_rsp = 255;
flags = IREQ_CACHE_FLUSH;
ii = (inquiry_info*)malloc(max_rsp * sizeof(inquiry_info));
num_rsp = hci_inquiry(dev_id len max_rsp NULL &ii flags);
if( num_rsp < 0 ) perror("hci_inquiry");
for (i = 0; i < num_rsp; i++) {
ba2str(&(ii+i)->bdaddr addr);
memset(name 0 sizeof(name));
if (hci_read_remote_name(sock &(ii+i)->bdaddr sizeof(name)
name 0) < 0)
strcpy(name "[unknown]");
printf("%s %s\n" addr name);
}
free( ii );
close( sock );
return 0;
} 4. 然后编译:
gcc -o simplescan simplescan.c -lbluetooth
当然这里面只是简单扫描的 你要再写一些音乐播放的啊 远程通信的啊什么的...
