PRODUCT BRIEF
Roving Networks
Bluetooth Solution
Roving Networks 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 with Bluetooth
hands-free and headset accessories. However, establishing Bluetooth
data connections with Apple devices requires a unique discovery/pairing
sequence and negotiation with the Apple authentication co-processor.
APL modules are based on the standard RN-41 and RN-42, making them
footprint compatible. Power, ground and UART connections are identical,
and connection of the Apple authentication chip is direct to the module
via a 3-wire interface.
FEATURES
ƒƒ Discoverable/Connectable with iPhone, iPod or iPad
ƒƒ Allows dual profile Bluetooth connections to other smartphone or computing platforms
ƒƒ Automatically stores Bluetooth address of the last paired iPhone, iPod, or iPad device, for quick reconnection
ƒƒ Secure Simple Pairing (SSP) enables ‘no PIN code required’ operation
ƒƒ Supports the complete Roving Networks Bluetooth feature set
ƒƒ Direct hardware connection to the authentication coprocessor
ƒƒ No iAP firmware development required for authentication on host microprocessor
ƒƒ Class 1 (~100m) and Class 2 (~30m) versions available

iPhone, iPad and iPod Accessories
All products designed to connect to iPhone’s, iPod’s
and iPad’s including those that incorporate the Roving
Bluetooth APL module must be registered and approved
with Apple’s Made for iPod (MFi) program.
Developers of such products should visit Apple’s
developer portal at: http://developer.apple.com/ipod/
With MFi membership, engineers can purchase
the evaluation kit which includes detailed
documentation and support.
The RN-4x-APL-EVAL evaluation kits include:
ƒƒ RN-4x-APLX development board which contains:
–– RN-4x-APL module
–– Apple authentication co-processor
–– Status LEDs
–– Power regulation
–– RS232 and TTL signals
