您好!关于Linux C树莓派蓝牙编程,您可以使用BlueZ库进行编程。具体步骤如下:
1. 在终端中输入以下命令,安装BlueZ库:
```
sudo apt-get update
sudo apt-get install bluez
sudo apt-get install libbluetooth-dev
```
2. 打开蓝牙:
```
sudo hciconfig hci0 up
```
3. 扫描周围的蓝牙设备:
```
sudo hcitool scan
```
4. 使用C语言代码连接蓝牙设备,例如连接名为“MyDevice”的设备:
```c
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/socket.h>
#include <bluetooth/bluetooth.h>
#include <bluetooth/rfcomm.h>
int main(int argc, char **argv)
{
struct sockaddr_rc addr = { 0 };
int s, status;
char dest[18] = "XX:XX:XX:XX:XX:XX"; // MyDevice的MAC地址
// allocate a socket
s = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
// set the connection parameters (who to connect to)
addr.rc_family = AF_BLUETOOTH;
addr.rc_channel = (uint8_t) 1;
str2ba( dest, &addr.rc_bdaddr );
// connect to server
status = connect(s, (struct sockaddr *)&addr, sizeof(addr));
// if successful
if( status == 0 ) {
char buf[1024];
memset(buf, 0, sizeof(buf));
printf("Connected successfully!\n");
// 接收数据
status = read(s, buf, sizeof(buf));
if( status > 0 ) {
printf("Received data: %s\n", buf);
}
}
else {
perror("Connection failed");
}
close(s);
return 0;
}
```
以上是一个简单的示例代码,您可以根据自己的需求进行修改和扩展。希望对您有所帮助!
