Thank you so much Chris!

Your particular description should help many others who may encounter the same question. In fact,when the module as a slave, it should also be connected by the computer. However, it may fail sometimes, so you need to try many times. If it canā€™t work at last, set the module as a master is also a feasible way.

Hy,

i have a bluetooth master/slave device.

The device is configured as master, but i have a problem!

I have a laptop pc and a bluetooth master/slave configured as master.

If i try to discover devices using the bluetooth device i find my pc and can connect to the pc, but i want also to do the oposite, but my laptop pc doesnā€™t find the bluetooth module!
How can i put the master device in discoverable mode?

Thanks

Try to make the buletooth module as a slave by using command \r\n+STWMOD=0\r\n;
Then make the module be inquiredable \r\n+INQ=0\r\n,

At this point, your pc should find the buletooth device!

May this helpful to you, and feel free to ask any quesiton!

I need to set the module as master!

I have another problem! How can the master connect with 2 or more slaves ??
If i connect to one slave if i try the +conn, the command is interpreted as a string to send to the first slave!!

#9

The module could not be searched when in master mode. So you must set it to slave.

The master moulde can only connect to one slave at a time.

Try to use command \r\n+STAUTO=0\r\n to forbidden auto-connect the last paired device before the slave device is powering.
So that the buletooth module will be in command mode when powered.

Hello everyone I have a problem I should set it to master links sonop I state that all correct because when I insert the Windows 7 at command responds ok but when I send the command +STWMOD=1 says nothing please help me thanks :wink:

#11

I have the same problem :
I connected this module trought my uart pcb to my pc . and i have configurated
When i send ā€˜atā€™ the module respond ā€˜okā€™ but it dosnā€™t respond to any other commands .
Please i need help too .

I have tried everything mentioned here to make BTBee work with Bees Shield and still it is not working !

#13

Hi,

How did you do that? General progress will be helpful me to analyze the problem.

Hello Icing,

I have successfully connected from my PC and windows phone and terminal on the android phone. However, I am not able to connect using the amarino app on android.

So I do not think that the bluetooth bee is the problem.
I guess i will contact the amarino developerā€¦ any suggestions?

Thanks !

#15

Hi,

I configure the master/slave as slave, if i power up the device it starts as a slave, i put the slave device discoverable using INQ comand, but when i power off the device and power up again the slave is no more in discoverable mode! how can i maintain the discoverable mode after power down?

Thanks for any help

Hello! im stacked in this step! i cant keep going with my project if i cant conect thisā€¦
How i can configure a bluetooth bee without a UartSB?? i got a arduino Uno, and a Seeeduino xbee shield.
thanks for ur help !

#17

hi everyone, firs, my english isnā€™t realy good, and i started playing with electronics recently.
I bought the Bluetoth in seeedstudio, and iā€™m trying to get it working: iā€™m using as arduino uno, i bought also a xbee shiled (only the pcb and de pins), finally, iā€™m using the following code:[code]#include <NewSoftSerial.h> //Software Serial Port

#define RxD 11
#define TxD 12

#define DEBUG_ENABLED 1

NewSoftSerial blueToothSerial(RxD,TxD);

void setup()
{
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
setupBlueToothConnection();

}

void loop()
{

if(blueToothSerial.read() == ā€˜aā€™)

{
blueToothSerial.println(ā€œYou are connected to Bluetooth Beeā€);
//You can write you BT communication logic here
}

}

void setupBlueToothConnection()
{
blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
delay(1000);
sendBlueToothCommand("\r\n+STWMOD=0\r\n");
sendBlueToothCommand("\r\n+STNA=SeeeduinoBluetooth\r\n");
sendBlueToothCommand("\r\n+STAUTO=0\r\n");
sendBlueToothCommand("\r\n+STOAUT=1\r\n");
sendBlueToothCommand("\r\n +STPIN=0000\r\n");
delay(2000); // This delay is required.
sendBlueToothCommand("\r\n+INQ=1\r\n");
delay(2000); // This delay is required.

}

//Checks if the response ā€œOKā€ is received.
void CheckOK()
{
char a,b;
while(1)
{
if(int len = blueToothSerial.available())
{
a = blueToothSerial.read();

if('O' == a)
{
  b = blueToothSerial.read();
  if('K' == b)
  {
    break;
  }

}

}
}

while( (a = blueToothSerial.read()) != -1)
{
//Wait until all response chars are received
}
}

//Send the command to Bluetooth Bee
void sendBlueToothCommand(char command[])
{
blueToothSerial.print(command);
CheckOK();
}[/code] in spit off this, when iā€™m trying to find the device with a cellphone or a laptop, nothing apens, the green keeps blinks two times / second, what iā€™m missing? someone can help me?

regards.

#include <NewSoftSerial.h>

NewSoftSerial mySerial(11, 12);

void setup() {
Serial.begin(38400);

mySerial.begin(38400);

}

void loop() {
if (mySerial.available()) {
Serial.print((char)mySerial.read());
}
if (Serial.available()) {
mySerial.print((char)Serial.read());
}
}

This is the code Fanfarra, with this code you have to configure xbee with sscomm
sorry for my english

#19

AHA!!! Thanks Mazz!

Ridiculous as it may seemā€¦ Iā€™ve been bashing my head against the wall with thisā€¦ your addition of ā€œb[/b]ā€ makes it all work. In the code example from the Seeeduino wiki, thereā€™s no ā€œb[/b]ā€. GRRR.

Thanks for that little gem!

Hi,
i have a little prob. with my new Serial port bluetooth module (Master/Slave)
if i connect it with my pc via sscom32e i got for example:
+
+STWMOD=1
OK
WORK:MASTER
+BTSTATE:0
+BTSTATE:1
+BTSTATE:3
CONNECT:FAIL
+BTSTATE:1

+INQ=1
OK

+BTSTATE:2

+RTINQ=44,11,E0,AC,70,2A;Galaxy S
+
+CONN=44,11,E0,AC,70,2A

OK

+BTSTATE:3

CONNECT:FAIL

+BTSTATE:1

and my mobile phone gave me an error! Phone itā€™s a <> BT 3.0
if i try as Slave i donā€™t get anything (no Require; pincode)

And what is the meaning of this message?
+BTSTATE:0
+BTSTATE:1
+BTSTATE:3
CONNECT:FAIL
+BTSTATE:1

Please Help!

TY :slight_smile:

Hi,

I have problems connecting my Bee in Linux.
I tried to follow the guide from the wiki. So I can see it, and pair it. But I cannot open the rfcomm via cutecom. The error message didnā€™t really help. Is there another way I can try (maybe via commandline) to open the rfcomm device?
I also tried pairing via hcitool. It works too. But browsing the device with sdptool doesnā€™t show any services. Is that supposed to be that way?

I tried it with Windows and it worked. But it wonā€™t help me with my Linux application :wink:

So has someone a suggestion?

Thank you in advance.

Best regards,

Hello,
I have a ARM Cortex M3 Board and connected the Module, but when I use this Code, I dont see the BT Device in my Windows. :frowning:
What Iā€™m doing wrong ???

void SetupBT (void)
{

/* USART2 Clock an*/
RCC_APB1PeriphClockCmd(RCC_APB1Periph_USART2, ENABLE);

GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_Init(GPIOA, &GPIO_InitStructure);

/* Configure USART2 CTS and USART2 Rx as input floating */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_3;

}

please help me, Iā€™ve bought 10 modules for my ten devices.
I want to setup a connection with my PC but I dont find the device with my BT Dongle. I measured VCC and its at 2,7V-3V

Iā€™m using it with ARM Cortex M3 from ST (STM32F103ZE)

Is my procedure correct?

with regards
Sam
