Introduction
Thank you for choosing Radicom RB8762 Module. We are committed to providing you
quality service and technical support. The RB8762 modules are designed to meet OEM’s
needs of embedding low power, wireless data connectivity to their products. The RB8762
family offers a quick and simple solution for wireless Bluetooth communications.
The Radicom RB8762 module is designed to meet the emerging market for Bluetooth 4.2
applications. These embedded Bluetooth 4.2 modules integrate entire profiles, applications,
and Bluetooth protocol stack, so no external processor is needed. The module contains an
internal S-Flash so custom parameters and settings can be easily loaded into these modules.
The RB8762 can be factory configured for other Bluetooth cost-effective and power-efficient
wireless consumer products such as watches, medical sensors, mice, TV remote controls and
fitness trainers. Contact Radicom for help to add the BLE Data Protocol functionality to your
4.0 Bluetooth device or for help in determining which Bluetooth Module is the best fit for
your particular Bluetooth application.
The RB8762 family modules can be powered with standard 3V3 low power. In lowest mode
it consumes only uA level power and will wake up in few hundred microseconds. The
RB8762 family provides superior performance in the presence of interference from 802.11
(WiFi) wireless devices and other 2.4GHz radios.
The RB8762 modules support quick connections and data transfers allowing an application
to establish a Bluetooth connection within a few milliseconds for short communication bursts
before quickly disconnecting the Bluetooth connection to save power. It takes much less
time to make a connection than conventional Bluetooth wireless technology and consumes
th
approximately only 1/20
The RB8762 is available in surface mount (SMD) or through-hole (Dip) hardware designs.
The RB8762 module is the surface mount model. The RB8762 can also mounted on a
conversion board to create the RB8762HM model for serial through-hole designs.

RB8762EVK and BLE Functionality
Radicom provides RB8762EVK Development Kits to provide a quick platform for testing
and evaluating the RB8762 and RB8762HM Bluetooth modules. The kit includes two
RB8762 modules mounted on the RB8762HM Dip Module. Each RB8762HM is installed
into a RB8762MB evaluation board. One of the RB8762HM is configured to operate in BLE
Data Protocol Master mode. The other RB8762HM is configured to operate in BLE Data
Protocol Slave mode. The RB8762MB boards have an RS232 Serial Port Connector that
allows the user to immediately connect to any standard serial port to evaluate the Bluetooth
modules.
The RB8762 modules are defaulted to use the BLE Data Protocol. For BLE Data Protocol
operation, you need one Radicom Master and one Radicom Slave module. The Slave Model
RB8762-S advertises or broadcasts the Bluetooth signal. The Master Model RB8762-M will
scan for Bluetooth signals and then request a Bluetooth connection. The RB8762-S Slave can
then accept the connection for BLE Data transfers. The RB8762-S Slave can also operate
with remote devices that also support the BLE Data Protocol.

* The Current Consumption is code dependent. Bluetooth functions and characteristics
will vary depending on the application firmware that is loaded into the RB8762 module.
The standard code is for BLE Slave. Using any RB8762 I/O (output) will draw more
current and change the overall current consumption.
