Yeah sorry I realise my questions was quite vague, I wrote it as I was running out the door to go somewhere.
At this point I have an ArduinoBT which is hooked up to an accelerometer which seems to be working fine and an LCD display. I’m using the accelerometer for simple gesture tracking. When a gesture is recognised I’m looking to get the Arduino to send a message to my iPhone to tell it what kinda of gesture was recognised.
On the iPhone side of things, I have a basic app which can send and display twitter messages using the MGTwitter engine. When a gesture is recognised the iPhone will retrieve the current location, in the form of a place name or address, potentially identify the friends you’re with, structure this into a Twitter message which will get sent back to Arduino to be shown on the LCD display. The use can then choose to post this message on Twitter, or decline sending it, by pressing a button connected to the Arduino.
Essentially the project allows for gesture-triggered or assisted Tweeting, taking you away from purely screen-based interaction. There is a little bit more to it, but that the essence of the project. The main hurdle I’m trying to get over at the moment is just sending messages to and from the devices using bluetooth. My iPhone is hooked up with a developer account and provisioning profile, but I have no problem jailbreaking if need be.
I found this page (next post), which appears to be what I am looking for, at least to my understanding. Can anyone confirm this? Sorry as I said I’m fairly new to iPhone, Arduino and BT, so there are a lot of things which are a little hazy in my mind.
Thanks for the feedback so far and sorry for the ambiguous nature of my initial question.
