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. ■ Discoverable/Connectable with iPhone, iPod or iPad ■ Dual prole allows Bluetooth connections to other smartphone or computing platforms ■ Automatically stores Bluetooth address of the last paired device, for quick reconnection ■ Secure Simple Pairing (SSP) enables ‘no PIN code required’ operation ■ Supports complete Microchip Bluetooth feature set ■ Direct hardware connection to the authentication co-processor ■ Authentication without iAP rmware development Development Tools Product Selector Module RN-4x-APL-EVAL Evaluation Kits Include: ■ RN-4x-APLX development board which contains: • RN4xAPL-I/RM module • Apple authentication co-processor • Status LEDs • Power regulation • RS232 and TTL signals ■ Four RN4xAPL-I/RM modules ■ Complete design documents including schematics ■ Source code for the Microchip Diagnostic Application
