Bluetooth® Modules That Simply Work

with iPhone®, iPad®, and iPod® Devices

Summary

Microchip’s Bluetooth APL modules natively support iAP

(iPod Accessory Protocol) data connections and directly

manage authentication, reducing engineering effort and

cost, and simplifying accessory product design.

Apple® iOS devices such as the iPhone freely connect via

the Bluetooth hands-free and headset profiles. However,

establishing Bluetooth data connections with an iPhone,

iPad or iPod requires a specific discovery class and

authentication. Every Bluetooth accessory must have an

Apple authentication co-processor.

APL modules are based on the standard RN41-I/RM

and RN42-I/RM, making them footprint compatible.

Power, ground and UART connections are identical, and

connection of the Apple authentication IC is direct to the

module via a 2-wire interface. The Apple authentication

IC is not part of the module. Customer must join and

purchase authentication ICs through the MFi program.
