Logitech Cordless Presenter (Bluetooth) and mysterious 4th button
by margolid＠gaia.ecs.csus.edu 30 Apr '04

30 Apr '04

Hello, I just bought the following: http://www.logitech.com/index.cfm/products/details/US/EN,CRID=3,CONTENTID=4… This is a bluetooth-powered presentation mouse from Logitech. I got it to communicate with my powerbook over built-in bluetooth with no problems. The mouse has two modes: mouse and presenter. When in mouse mode, you just put the thing on the desk/table and it works exactly as advertised (though Logitech doesn't officially support Macs for this product). Left button, right button, and the up/down scroll buttons all work great. When you put the mouse in presenter mode (via a little button on the bottom), you loose the mouse part, and you're supposed to get functionality for left button, right button, and built-in laser pointer. The problem is that in presenter mode, my right button disappears, so I only get the left mouse button and the laser. I want to be able to program these two buttons for back/forth in Web-based (powerpoint-like) presentations. Since the left mouse button is still behaving, I was able to map this button to the right-arrow key with GamePad Companion. However, gamepad companion nor OS X (Panther), seem to be detecting the other button. I ran the "xev" program in X11 to see if that would detect the click, and yes, xev tells me that in presenter mode, the right mouse button is "Button 4". By the way, in regular mouse mode, the right button is button 3. Gamepad Companion allows for a mapping of up to eight mouse buttons, but I've tried them all and none seem to be grabbing this input. I also installed uControl, to see if this program would work, but it didn't have any mouse mapping options (except some basic things like flipping right to left). USB Overdrive doesn't detect the bluetooth mouse at all. If X11 can detect the input, doesn't that mean that on some level, the native OS can see it too? How can I capture this input and remap it to a keyboard press (or something else, like a regular right click)? Thanks in advance for your help, Dave Margolis _______________________________________________ bluetooth-dev mailing list | bluetooth-dev(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.

latency?
by Sukandar Kartadinata 26 Apr '04

26 Apr '04

I'm considering to use Bluetooth to send sensor data to a Mac (PC too). Being new to this I'd be curious to know what latency can be achieved at what data rates. I'm looking for less than 20ms (and stable!) latency with at least 200kbits/s. Is this possible ? I made some simple experiments with serial adapters, but all my machines started to choke at 115kbaud. I think I'd prefer a synchronous connection (maybe using an audio profile ?). Does a suitable profile exist for this ? thanks, Sukandar _______________________________________________ bluetooth-dev mailing list | bluetooth-dev(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.

Getting list of local services
by Scott Gruby 20 Apr '04

20 Apr '04

I know that this question has been asked before, but I didn't see a response to it (I've searched the archives). What I'd like to do is to get a list of IOBluetoothSDPServiceRecordRef on the local machine so that I can iterate through them looking to see if one or more matches a particular service. My goal, really, is to find the first service that is a ClassSerialPort, get the channel and listen for connections on that channel (yes, I want to listen on an already registered service as I don't control the device side that already connects to the serial port service). I've been unable to figure this out through documentation and experimentation. Is this even possible? I know that I can get the services on a remote device using IOBluetoothDeviceGetServices (after doing an SDP query), but nothing seems to work for the local machine. Any ideas?

Bluetooth Firmware Updater released today
by Stephen Martin 19 Apr '04

19 Apr '04

About Bluetooth Firmware Updater Provides improvements in the update installation process, better performance when waking the computer from sleep, and support for additional key commands during startup. The Bluetooth Firmware Updater is for D-Link USB Adapters (revision B2 or later), and Apple internal Bluetooth modules on PowerBooks and PowerMacs. This firmware update will improve connectivity between the computer and the Apple Wireless Keyboard and Mouse. Use this updater for the modules specified above; this updater is unsupported with any other Bluetooth modules. Important: Applying this firmware updater to a D-Link USB to Bluetooth adapter will make it incompatible with non-Macintosh systems. http://www.apple.com/downloads/macosx/apple/ bluetoothfirmwareupdater.html -- Stephen R.

Re: SCO problems with my custom HCI controller
by Alexander Traud 18 Apr '04

18 Apr '04

> The SendSCOData() function should work virtually identically to > SendACLData(). Thanks for this answer. But it won't work. The IOMemoryDescriptor has a constant length of 816 bytes. SCO and eSCO packets over HCI only allow a maximum of 255 bytes. And we get the same two packets constantly. If we return an error, success, call the call back routine with an error or a success - we get back the same packet all the time. Even rewriting the code to be truly asynchronous (first return SendSCOData( ) with success and then calling the SendSCOCompleted( ) with success) there is not much change within the behaviour. Well, perhaps anyone on the net finds our bug. The source is included and public domain. Are you using the PCM gate of the CSR chip? You seem to use a very special CSR firmware which isn't available even to "normal" OEMs and consequently I do not find any documentation on this CSR firmware you install with your firmware updater. _______________________________________________ bluetooth-dev mailing list | bluetooth-dev(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/bluetooth-dev Do not post admin requests to the list.

[mRFCOMMChannel writeSync:"at+cmgf=1/n" length:16]; Do I make mistakes? Thanks for your help. There are three mistakes on that last line. Firstly, the length of the data you are sending looks like it was intended to be 10 bytes, so you need to set the length to that. Since you are only sending strings rather than binary data I would recommend using something like: char *s; ... s = "<your command to send>"; [mRFCOMMChannel writeSync: s length: strlen(s)]; Secondly, you have the slash the wrong way around; I'm pretty sure that you meant to write "at+cmgf=1\n" Thirdly, you shouldn't be using "\n" (new line) anyway, you should be sending a "\r" (carriage return) instead.

Re: Enter at commands to mobile phone using bluetooth
by Nathanael P 16 Apr '04

16 Apr '04

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?

I have opened a rfcomm channel synchronously: [selectedDevice openRFCOMMChannelSync:&mRFCOMMChannel withChannelID:10 delegate:self]; [mRFCOMMChannel retain]; I have a problem: I've tried to enter the at commands using writeSync, but there's no response. I have no idea how to read the incoming data from the mobile phone. How to write the at commands and read the incoming data? Note that on many phones you will need to send the command string terminated by a \r, rather than the more usual \n. This caught me out on my SonyEricsson T630 for a while.
