Re: Enter at commands to mobile phone using bluetooth

16 Apr 2004

      I am an university student currently doing a final

project and I am a newbie in xcode programming. I am

going to write a program with xcode that could sends

at command using bluetooth and recieve response (like

hyper terminal in windows). The input and the output

are both 2 NSTextField (1 for input, 1 for output).

For my first try, I learned from the example that

bundled with mac os 10.3. Would you please explain me

how to implement that code? Where should I put the

code? This is the code I have written so far:

IOBluetoothRFCOMMChannel

*mRFCOMMChannel;

IOBluetoothDevice

*selectedDevice;

IOBluetoothDeviceSelectorController

*deviceSelector;

NSArray                                 *deviceArray;

deviceSelector = [IOBluetoothDeviceSelectorController

deviceSelector];

[deviceSelector runModal];

deviceArray = [deviceSelector getResults];

selectedDevice = [deviceArray objectAtIndex:0];

[selectedDevice openRFCOMMChannelSync:&mRFCOMMChannel

withChannelID:10 delegate:self];

[mRFCOMMChannel retain];

[mRFCOMMChannel writeSync:"at+cmgf=1/n" length:16];

Do I make mistakes? Thanks for your help.

Since you correctly registered yourself as delegate

should implement:

-

(void)rfcommChannelData:(IOBluetoothRFCOMMChannel*)rfcommChannel

data:(void *)dataPointer length:(size_t)dataLength;

to receive data. There are more delegate methods you

may need, the full
