我正在尝试将运行 ubuntu 12.04 的笔记本电脑连接到连接到 arduino 的蓝牙 Mate Silver。
接线是:
CTS-I->No connection (leave floating)
VCC->5V
GND->GND
TX-O->D2
RX-I->D3
RTS-O->No connection (leave floating)
在 arduino 上运行的代码:
$include <SoftwareSerial.h>
int bluetoothTx = 2; // TX-O pin of bluetooth mate, Arduino D2
int bluetoothRx = 3; // RX-I pin of bluetooth mate, Arduino D3
SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);
void setup()
{
Serial.begin(9600); // Begin the serial monitor at 9600bps
bluetooth.begin(115200); // The Bluetooth Mate defaults to 115200bps
bluetooth.print("$$$"); // Enter command mode
delay(100); // Short delay, wait for the Mate to send back CMD
bluetooth.println("U,9600,N"); // Temporarily Change the baudrate to 9600, no parity
// 115200 can be too fast at times for NewSoftSerial to relay the data reliably
bluetooth.begin(9600); // Start bluetooth serial at 9600
}
void loop()
{
if(bluetooth.available()) // If the bluetooth sent any characters
{
// Send any characters the bluetooth prints to the serial monitor
Serial.print((char)bluetooth.read());
}
if(Serial.available()) // If stuff was typed in the serial monitor
{
// Send any characters the Serial monitor prints to the bluetooth
bluetooth.print((char)Serial.read());
}
// and loop forever and ever!
}
当我在 ubuntu 中打开蓝牙管理器时,我发现蓝牙伴侣是可见但未知的,并且当我右键单击它时没有 SPP 连接选项。我浏览的所有教程和博客都通过 SPP 选项连接到蓝牙伴侣。

那么现在我如何连接到蓝牙伴侣?
