The SPBT4.0DP is an easy to use Bluetooth Smart Ready module, compliant with Bluetooth
v4.0.
The module is among the smallest form factor available which provides a complete RF
platform. The SPBT4.0DP enables electronic devices with wireless connectivity, not
requiring any RF experience or expertise for integration into the final product. The
SPBT4.0DP module, being a certified solution, optimizes the time to market of the final
applications.
The module is designed for maximum performance in a minimal space including fast speed
UART and 8 general purpose I/O lines, several serial interface options, and up to 800 kbps
transmission speed with SPP service active, 250kbps with iAP2 service active.
Optimized design allows the integration of a complete working Bluetooth modem, including
antenna, in the minimum possible size; only an additional external LPO (low power
oscillator) is required to enable low power mode capability.
The SPBT4.0DP is a surface mount PCB module that provides fully embedded, ready to
use Bluetooth wireless technology. The reprogrammable Flash memory contains
embedded firmware for serial cable replacement using the Bluetooth SPP profile.
Embedded Bluetooth DATA PACKAGE (DP) firmware is a friendly interface, which realizes a
simple control for cable replacement. The SPBT4.0DP supporting SPP, iAP2 and Bluetooth
Low Energy proprietary Data Exchange profiles, it provides communication with Android,
smartphone, and the newest Apple® iOS Bluetooth enabled devices.
An Apple authentication IC is required to exchange data with an Apple device or access an
Apple device application. The DP FW includes the Bluetooth iAP2 profile capable of
recognizing the Apple authentication chip.
Customers using the Apple authentication IC must register as developers to become an
Apple certified MFI member. License fees may apply, for additional information visit:
http://developer.apple.com/programs/which-program/index.html.
Certified MFI developers developing electronic accessories that connect to the iPod®,
iPhone®, and iPad® gain access to technical documentation, hardware components,
technical support and certification logos.
Customized firmware for peripheral device interaction, power optimization, security, and
other proprietary features may be supported and can be ordered pre-loaded and configured.

6 Hardware design
SPBT4.0DP module with DP command embedded FW supports UART, I2C and GPIO
hardware interfaces.
Note: - All unused pins should be left floating; do not ground.
• All GND pins must be well grounded.
• The area around the module should be free of any ground planes, power planes, traceroutings, or metal for 6 mm from the module antenna position, in all directions.
• Traces should not be routed underneath the module.
6.1 Reflow soldering
The SPBT4.0DP is a high temperature strength surface mount Bluetooth® module supplied on
an 18 pin, 6-layer PCB. The final assembly recommended reflow profiles are indicated here
below.
Soldering phase must be executed with care: in order to avoid undesired melting
phenomenon, particular attention must be paid to the set-up of the peak temperature.
Here following some suggestions for the temperature profile based on the following
recommendations.
