在一天的大部分时间里,我一直试图让 BlueZ 在我的 Ubuntu 桌面上工作。它只是行不通。我可以通过系统对话成功地将我的设备与我的计算机配对,但 BlueZ 扫描从未找到任何东西。BlueZ 有替代品吗?如果设备已经配对,有没有办法在没有 BlueZ 的情况下操作蓝牙设备?
为了更好地衡量,这是我一直在运行的代码(http://people.csail.mit.edu/albert/bluez-intro/c404.html#simplescan.c):
#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;
}
