Fantastic information! Thanks. I wanted to try making an iPhone app that would emulate a bluetooth number pad I could use with a laptop or in conjunction with one of the compact iMac keyboards. I know there's an app that lets you use the iPhone as a number pad, but it's WiFi and requires the installation of software... I thought it would be neat if you didn't have to do that. I've been looking around trying to see whether it's possible to use a iPhone to emulate a bluetooth keyboard (no real reason, just think it would be a fun exercise). I can't find any information either way; could someone point me in the right direction? whether this is possible depends on your "setup". Using Apple's iPhone SDK and any OS up till 3.0, it is impossible - mainly because Apple only provides an API for "Made for iPhone" BT accessories and for Bluetooth Gaming between multiple iPhones. However, the iPhone does contains a popular Cambridge Silicon Radio (CSR) chipset with a standard Bluetooth HCI interface. So in theory, you could run any standard user-space Bluetooth stack you can find and do whatever you want, including sending key events as standard HID events over an L2CAP channel. So far, people successfully used at least the following 3 open- source Bluetooth stacks on the iPhone to get some Bluetooth functionality: * the lwBT stack: http://www.sm.luth.se/~conny/lwbt/ * the stack that comes as part of the BTnode research platform: http://www.btnode.ethz.ch * the new BTstack project: http://code.google.com/p/btstack None of these will allow you to sent your key events right away, but it might be interesting to have a look. To summaries the answer to your question: yes, it is possible, but sadly only on a jailbroken iPhone. What use case did you have in mind, when asking for BT keyboard support (even though for a fun excercise) ? This email sent to site_archiver@lists.apple.com
