content: Hello wizards of the EEVBLOGI am working on a project witch involves a data gathering PCB with an atmel at32uc3c micro.this PCB will be situated in a car, gathering live data from the car.This data will then be transmitted to an IOS device for logging and live data monitoring via a custom app.There will also be a way to communicate back to the pcb and send simple commands.However this is where i've got stuck, i have basically no experience at all in wireless cuminication with apple devicesAnd what i've heard is that apple (being apple) have got some costom way of doing things and only certified chips work properly!?Can somebody give clarity to this and perhaps give examples of wifi or bluetooth modules /chips that would be suitible for this type of application (even combined chips/modules are welcome).Thanks for an awesome community (excuse my spelling(i'm from Sweden)) <-- double parenthesis O0

content: I think BLE is unrestricted, but BT itself you need the AP chip from Apple, and you can only obtain one if you sign up to their MFi developer subscription and stand on one leg with your arse pointing upwards.I think WiFi is unrestricted also.

content: Not sure which Apple devices support BLE though, I think WiFi is unrestricted (in the sense you don't need the AP chip).The AP is the authentication processor, means Apple can lock consumers into their approved products, now you could see this as a positive that everything that is designed to work on your Apple device that has a working classic Bluetooth device is Apple certified, or you could look at it as forcing developers to go through unnecessary expense just to do something simple.There was a whole kick up about Apple and Bluetooth sharing of files (in that you couldn't) a while ago, looks like it is not going to get any better for developers any time soon though, they are introducing MAC scrambling now on discovery.

content: Sometimes apple just gets on my nerves!oh whell i will just have to make do with wifi instead, perhaps the cc3000 from TI or one of atmels ATWINC1500 modules

content: Hey OP,There's a comparison chart of some bluetooth modules that you can find here.http://blog.upverter.com/post/102541328427/bluetooth-moduleFull disclosure; I work with upverter, and if there's anything you need, let me know!
