WiFi & the iPod Touch

site_archiver(a)lists.apple.com Delivered-To: bluetooth-dev(a)lists.apple.com Thread-index: AcjV3iiPZwrqFkHREd2dUAAf81C/bw== Thread-topic: WiFi & the iPod Touch User-agent: Microsoft-Entourage/11.3.6.070618 Apologies for the non-Bluetooth nature of this question, but after extensive searching I could find no better list to use for my query. My question regards the iPod Touch, and its out-of-the-box WiFi capabilities. We are using an Ad-Hoc WiFi network, and wish to connect a new iPod Touch to it. Our problem appears to be that the iPod wants to make a first-time connection to an Infrastructure-mode WiFi AP first, maybe in order to send a 'Hello' message to an Apple server. After making this first-time connection, the iPod can connect to an Ad-Hoc WiFi AP fine. My question is, can anyone suggest how we could use an Ad-Hoc WiFi network for an iPod connection out of the box? Can the iPod be fooled into connecting to the internet via Ad-Hoc WiFi the first time? Any / all guidance or referral within Apple or the dev community very much appreciated.

IOBluetoothLocalDeviceReadAddress and 64 bit

site_archiver(a)lists.apple.com Delivered-To: bluetooth-dev(a)lists.apple.com Hi, Any clues? I'm running OS X 10.5.3. on a MacBook Pro. M. _______________________________________________ Do not post admin requests to the list. They will be ignored. Bluetooth-dev mailing list (Bluetooth-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/bluetooth-dev/site_archiver%40lists.… I just tried to recompile our JNI BT-Library with 64 Bit support to make it ready for Java1.6. Most of it worked with no problems, but some simple functions do not work in 64 Bit mode. IOReturn ret = IOBluetoothLocalDeviceReadAddress (&localBTAddress, NULL, NULL, NULL); returns an error when called from Java 1.6.0 (64Bit) and returns 0 from Java 1.5 (32 Bit). The code is the same otherwise and this is happening in my BT-Thread. So nothing special here. This email sent to site_archiver(a)lists.apple.com

The long answer: device 'range detection' is generally discouraged due to the interference it can cause. When two devices want to connect, the master device must scan the 2.4GHz range in order to synchronize frequencies with the slave device. Bluetooth connections use spectrum hopping to avoid interference with other 2.4GHz devices, but this initial scan for setting up the connection is like firing a shotgun into the air. A single shot may not do much, but do it enough and you're going to start hitting things. Expect decreased wireless reception as well as dropped WiFi and Bluetooth connections, interference with cordless phones, etc. The short answer: I've found name requests to cause the 'least' amount of interference. Don't initiate them AT ALL when a device is pairing (it will mess up device discovery). Don't initiate more than one at a time. Don't initiate more than one every 60 seconds. b - what is the status of the IOBluetooth framework on TIger and Leopard regarding multithreading, is the framework thread safe? No. Not thread safe. It's best to keep everything on the main thread. It might be possible to use a single thread instead; this has been discussed in the past, but i can't remember what the conclusion was. You might want to search the list. Okay, I came to the same conclusion when I saw the result on Tiger & Leopard. c - what could possibly go wrong in what I've done so that I'm not able to open and RFCOMMChannel ? Try moving everything to the main thread. Okay, I've moved eveything in the main thread, and it is working like a charm now! Thanks. This email sent to site_archiver(a)lists.apple.com

After detecting the device disconnection, I try to look for the device and open a new connection but each time I got an error on openConnection wich is the expected behaviour. Once I start again the Bluetooth service of my phone, my application never receives a notifcation that the phone is connected and openRFCOMMChannelSync is failing each time with a 0x10000003 error code. 0x10000003 stands for MACH_SEND_INVALID_DEST from what I've seen but I'm not able to say much more about this error code.
