VU-BLE-V1 Bluetooth module
1.summary
VU-BLE-V1
4.0
Bluetooth
module
is
a
low-power wireless module, operating in the
world-wide ISM frequency band at 2.400 to
2.485GHz, using the latest high performance and
ultra-low power 4.0 wireless system chip nRF51822
from NORDIC Semiconductor in Norway. It’s
communication distance has been greatly expanded
with the professional design of Weiyou Intelligent
Technology Co. Ltd.
Lots of optimized matching
debuggings has been done in RF section, so in function, the emission
efficiency is highest and harmonic is minimum,and so that the interference with
other devices has been reduced to the minimum. At the same time, the
Bluetooth module is not easy to be disturbed by other equipment, the stability
has been greatly improved.
VU-BLE-V1 4.0 Bluetooth module is small in size and highly integrated
which can be embedded in the products of limited space easily.With high
sensitivity and low-power consumption, suitable for many types of products.
Software is embedded in the module, when power on the pairing is automatic.
In design, only a small amount of external circuits is needed to achieve specific
functions. Using this module, the product design cycle could be shorten and
the design efficiency could be improved.

4.Attentions in PCB Layout
Please pay attention to avoid the test pads area at the bottom of the Bluetooth
module, if vias must be placed in the area, please cover oil screen. The
antenna area of Bluetooth module should be as far away as possible from
metal,and no traces in this area. Copper polygn, power supply traces should
not go through the antenna area. Please place the antenna area at the edge of
the PCB.

6.Compare nRF51822 with other Bluetooth chips
(1)MCU
a.nRF51822
ARM®CortexTM-M0 32 bit processor (256/128KBytes Flash, 16K/32K RAM).
There are many customer groups of ARM, and the development of resources
are very rich.
b.TI
8 bit 8051 kernel which determines the performance could not match the
operation of Bluetooth protocol properly. And the power consumption is higher
than nRF51822.

c.CSR
16 bit MCU, external Flash/EEPROM is needed and can not encrypt the
product. So, the cost of product and the PCB area will increase.
(2)New Functions of nRF51822
a. Power management
Except system ON/OFF mode, every function block has it’s own power
management, it’s helpful to reduce the power consumption.
b.DC/DC converter setup
The nRF51822 DC/DC buck converter transforms battery voltage to lower
internal voltage with minimum power loss. Used with a 3V coil-cell battery, the
peak current drawn from the battery is reduced by approximately 25%.
c.The Programmable Peripheral Interconnect (PPI)
The Programmable Peripheral Interconnect (PPI) enables peripherals to
interact autonomously with each other using tasks and events independent of
the CPU. The PPI allows precise synchronization between peripherals when
real-time application constraints exist and eliminates the need for CPU activity
to implement behavior which can be predefined using PPI.
(3)Bluetooth Protocol and Application Codes
a.NRF51822
The storage of Bluetooth protocols and application codes are separated from
each other. Developers only need to concern how to develop the application
codes, do not need to acknowledge how to operate Bluetooth protocols. Only
API parameters need to be configured to run the system.
b.TI and CSR
Only provide Bluetooth source codes. Developers could only modify the
source codes, it’s hardly to program. Application codes and protocols are
mixed stored in the same storage area will bring great difficulties to check out
the root of the errors when programming.

(4)Crystals
a.NRF51822
Internal 32.768KHz crystal embedded, external crystal is no need.
b.TI and CSR
External 32.768KHz crystal is needed, the cost increase and the PCB area is
larger.
(5)Air-upgrade
a.NRF51822
Only to download the application code upgrading.It’ll not affect the use of
products If interrupted in upgrading.
b.TI and CSR
Bluetooth protocols and application codes are all need to upgrade. Products
will not work if interrupted in upgrading.
(6)Bluetooth Authentication
a.NRF51822
Bluetooth protocols and application codes are independent of each other, and
Bluetooth protocol’s certification is obtained, so only application codes need to
be authenticated. If new codes released, only application codes need to be
re-authenticated.
b.TI and CSR
Bluetooth protocols and application codes are all need to be authenticated. If
new codes released, the two both are all need to be re-authenticated.
