®
4.0 Certified ISM 2.4GHz module.
Utilizes the TI CC2540 SoC with 256K Flash, 8K RAM.
Over 150 meter (500 ft) line of site (LOS) distance with integrated antenna.
Can be externally controlled via simple ASCII AT commands over the UART or
programmed with custom applications embedded in the module.
Available embedded
Bluetooth
Protocols and Profiles include: GAP, GATT, SMP, ATT,
L2CAP, BAS, BLP, BLS, DIS, FMP, ANP, HIDS, HOGP, HID, HTP, HTS, HRP, HRS, IOP,
IAS, LLS, PASP, PXP, SCPP, SCPS, TIP, TPS, and BRSP.
The BR-LE4.0-S2 is identical to the BR-LE4.0-S3 with the exception of a USB controller
replacing the I2C of the S3. In addition, the S2 provides a higher maximum output
power.
FEATURES
Integrated AT.s command stack for external control via UART or RF, with master/slave support and serial
(BRSP) and battery (BAS) profiles. BRSP allows the user to stream data over LE similar to the way SPP
works on Classic
Bluetooth
devices, but at a much lower maximum data rate.
Available AT.e SDK for custom embedded applications on the module with approximately 130kB Flash and
2.5kB RAM available to the client application.
UART (2 or 4 wire with CTS/RTS, 9600 to 460.8K baud), SPI, and USB data interfaces.
12-Bit ADC with 8 channels, RTC, battery monitor, temperature sensor, watchdog timer.
Software adjustable transmitter power (-23dBm to 4dBm) for short to long range applications.
Very low power consumption:
27mA 0dB TX, RX down to 19.6mA, .9uA sleep w/timer, and 0.4uA deep sleep.
Compatible with TI TPS62730 step down converter which can extend battery life by up to 20%.
Secure and robust communication link:
FHSS (Frequency Hopping Spread Spectrum)
24-bit CRC Error correction for guaranteed packet delivery
AES-128 bit encryption using CCM for encryption and authentication of packets.
Firmware updates Over-the-Air (OTA) or over two wire UART interface.
Modules easily configured to advertise as iBeacons to support immediate, near, and far proximity ranges.
Free iOS & Android libraries and applications.

Bluetooth
Low Energy, part of
Bluetooth
Ver. 4.0, specifies two types of implementation:
single
mode and
dual
mode. Single mode chips implement the low energy specification and consume just a fraction of the power of
classic
Bluetooth,
allowing the short-range wireless standard to extend to coin cell battery applications for the first
time. Dual mode chips combine low energy with the power of classic
Bluetooth
and are likely to become a de
facto feature in almost all new
Bluetooth
enabled cellular phones and computers. Single mode
Bluetooth
4.0
Low Energy is
NOT
backwards compatible with previous
Bluetooth
standards. Dual mode
Bluetooth
4.0 Low
Energy is backwards compatible but is not practical for low power devices but targeted to gateway products.
An
nBlue
single mode module communicating over BLE once a second consumes ~30μA on average. To put this
in perspective, 30μA corresponds to 330 days of battery life using a CR2032 coin cell. BLE is not recommended
for data streaming applications but is ideal for efficient short (20 byte or less) packet bursts.
In LE, GAP defines four specific roles: Broadcaster, Observer, Peripheral, and Central. A device may support
multiple LE GAP roles provided that the underlying Controller supports those roles or role combinations. However,
only one LE GAP role may be supported at a given time. The
Broadcaster
role is optimized for transmitter only
applications. Devices supporting the broadcaster role use advertising to broadcast data. The broadcaster role does
not support connections. The
Observer
role is optimized for receiver only applications. Devices supporting the
observer role are the complementary device for a broadcaster and receives broadcast data contained in
advertisements. The observer role does not support connections. The
Peripheral
role is optimized for devices that
support a single connection and are less complex than central devices. Devices supporting the peripheral role only
require Controllers that support the Controller’s slave role. The
Central
role supports multiple connections and is
the initiator for all connections with devices in the peripheral role. Devices supporting the central role require a
Controller that supports the Controller’s master role and generally supports more complex functions compared to
the other LE GAP roles.

STANDARD LAND DIMENSIONS (WITH ANTENNA)
Note:
Radio requires a RF ground plane on the rest of the Printed Circuit Board (PCB) area. This can be located
on any layer of the PCB. Extend the RF ground plane parallel to module pins 31 and 32 the entire length of your
board. Connect all ground pins and do not notch the ground plane around the module. Bottom of module is
grounded so be careful of vias or conductive traces located under the modules that are not soldered masked to
prevent shorting. Keep metallic components, connectors, copper traces, internal layers, and ground planes away
from the antenna area in 3D space!
