Model Number: ITBM530
Bluetooth Test Kit ITBM530_52832
General Description:
The nRF51822 Development Kit includes nRF51822 modules that
integrate all required external circuitry, including antenna match,
16MHz crystal, and 32.768kHz crystal. When plugged into the nRFgo
Motherboard, the device I/O pins are easily accessible via the I/O
port headers on the Motherboard. The kit also includes a compact
nRF51822 USB dongle that can act as a Bluetooth Smart master
emulator when developing Bluetooth Smart applications.

R&Q:
- 5.0/4.2/4.0 Bluetooth module contrast difference
Bluetooth has been improved step by step from 4.0-4.2-5.0, bringing
more functions. Because the Bluetooth module uses different
versions of Bluetooth chips, the functions are different. Createk
develops and produces 4.2/5.0 low-power Bluetooth modules. The
comparison and differences of 5.0/4.2/4.0 Bluetooth modules are
listed below:
5.0 Bluetooth module relative to 4.2 Bluetooth module:
1) The transmission rate is increased by 2 times
Bluetooth 5.0 increases the current transmission speed by 2 times.
The maximum communication speed of Bluetooth 4.2 is 1Mbps, and the
maximum communication speed of Bluetooth 5.0 is 2Mbps.
2) The transmission distance has been increased by 4 times
The coverage of the Bluetooth 5 standard is 4 times that of
Bluetooth 4.2. Improve the accuracy of indoor positioning.
3) The information capacity of the broadcast mode is increased by 8
times
Its broadcast communication capacity has been upgraded from 31Byte
of Bluetooth 4.2 to 255Byte. The enhanced broadcasting capability
will bring better beacons to create more location-based indoor
positioning services and navigation services, and data transmission
can be realized without pairing and connection. , The accuracy of
indoor positioning is less than 1 meter,
4) Lower power consumption and compatible with older Bluetooth
versions
In order to meet the needs of the mobile Internet of Things, its
power consumption is lower and it is compatible with the old
Bluetooth version.
4.2 The Bluetooth module is relative to the 4.0 Bluetooth module:
1) Faster data transmission
Compared with 4.0, under the Bluetooth 4.2 standard, the data
transmission speed between devices is increased by about 2.5 times,
and the amount of data that can be accommodated in a Bluetooth
smart data packet is about 10 times that of the previous one.
2) Higher security
In addition, the security of Bluetooth 4.2 has also been improved.
If the user's permission is not obtained, the Bluetooth signal will
not be able to try to connect and track the user's device, and it
will not be able to perform intelligent positioning.
3) More powerful functions
On the other hand, the new standard also promotes the introduction
of the IPv6 protocol into the Bluetooth standard. Bluetooth 4.2
devices can directly access the Internet through IPv6 and 6LoWPAN,
and support low-power IP connections.
