MEAM is new to me, if that is like arduino you can do it the easy way and use a prebuilt module like HC-06 with Bluetooth 4.0 LE that communicate via serial interface - AT commands. Have not tested HC-06.

If you are serious about BLE and have time to spend and learn, buy a devkit from nordic and use the nrf51822 and rework some examples i C-code, you can also download iOS app LightBlue and simulate a peripheral.

In iOS, you need to join the developer program and read the "Core Bluetooth programming guide", also the Apple "Bluetooth Accessory design guidelines for apple products" contains advertise/Interval timings specific for iOS etc.

Also in the Nordic SDK download area you can find iOS app examples.

I have used some of the PTR series modules from Xuntong and these have more or less external IO pins with ADC etc, you program these in C probably much the same way you tend to program MEAM. Also to nrf51, you have the radio code lib precompiled (SoftDevice) and have to program this to one area and then your own code at another area/address.

here is a good place to start. The blog site has examples code for both the device and iOS. http://embeddedsoftdev.blogspot.ca/p/ehal-nrf51.html
