2. Codes Development Using Nordic Tools
Development tools by Nordic and other third party development tools recommended by Nordic should be
used .
Easy, fast and safe code development
Nordic development environment for nRF52840 offers a clean separation between application code
development and embedded protocol stacks. This means compile, link and run time dependencies with the
embedded stack and associated debugging challenges are removed. The Bluetooth low energy and ANT stack
is a pre-compiled binary, leaving application code to be compiled stand-alone. The embedded stack interface
uses an asynchronous and event driven model removing the need for RTOS frameworks.
Over-The-Air DFU
The nRF52840 is supported by an Over-The-Air Device Firmware Upgrade (OTA DFU) feature. This allows for
in the field updates of application software and SoftDevice.
SoftDevices
The Nordic protocol stacks are known as SoftDevices and complement the nRF52 Series SoCs. All nRF52
Series are programmable with software stacks from Nordic. This bring maximum flexibility to application
development and allows the latest stack version to be programmed into the SoC.
SoftDevices available from Nordic:
S140: Bluetooth low energy concurrent central/peripheral/observer/broadcaster stack.
Development Tools
Nordic Semiconductor provides a complete range of hardware and software development tools for the nRF52
Series devices. nRF52 DK board is recommended for firmware development.
Nordic software development tools can be downloaded from the following webpage.

BC840/M/E, Compact BLE 5, Thread, Zigbee Modules
Ver 1.00, April 2019
The 32 bit ARM Cortex M4F MCU with hardware supports for DSP instructions and floating point operations,
code density and execution speed are higher than other Cortex M MCU. The Programmable Peripheral
Interconnect (PPI) system provides a 20-channel bus for direct and autonomous system peripheral
communication without CPU intervention. This brings predictable latency times for peripheral to peripheral
interaction and power saving benefits associated with leaving CPU idle. The device has 2 global power modes
ON/OFF, but all system blocks and peripherals have individual power management control which allows for an
automatic switching RUN/IDLE for system blocks based only on those required/not required to achieve
particular tasks.
The radio supports Bluetooth low energy and ANT. Output power is scalable from a maximum of +8dBm down
to -20 dBm in 4dB steps. Sensitivity is increased to -96 dBm to -89 dBm, depending on data rate. Sensitivity for
BLE is -96 dBm, and -92.5 dBm for ANT.
The NFC block supports NFC-A tags with proximity detection and Wake-on-field from low power mode. The
NFC enables Out-Of-Band (OOB) Bluetooth pairing of devices and thus greatly simplifying deployment.
ARM Trustzone CryptoCell 310
ARM® TrustZone® CryptoCell-310 co-processor is a security subsystem which provides Root of Trust (RoT) and
cryptographic services for a device. CryptoCell services are available to the application through a software library API, not
a hardware register interface.

Mounting BC840 and BC840M on the Host PCB
The following figure shows recommended mounting of BC840 and BC840M module on the host PCB.
•
For the best Bluetooth range performance, the antenna area of BC840M module shall extend 5.5 mm
outside the edge of host PCB board, or 5.5 mm outside the edge of a ground plane.
•
For the best Bluetooth range performance, the antenna area of BC840 module shall extend 2.5 mm outside
the edge of host PCB board, or 2.5 mm outside the edge of a ground plane.
•
The next choice is to place BC840M on a corner of host PCB, the antenna area shall extend 5.5 mm from
the edge of ground plane. Ground plane shall be at least 5 mm from the edge of the antenna area of
module.
•
The next choice is to place BC840 on a corner of host PCB, the antenna area shall extend 2.5 mm from the
edge of ground plane. Ground plane shall be at least 5 mm from the edge of the antenna area of module.
•
We don’t recommend mounting BC840 module in the middle of a host PCB.

* Because of availability of nRF52840 CKAA SoC, Bluetooth range is measured from BC840E-ANT060 to
BT840E-ANT060. Ranges will be re-measured between two BC840Es when additional SoCs are received.
Deployment Recommendations
Sizes of modules of BC840 Series are similar. Measured ranges are from 4 meters to 1150 meters at 1Mbps.
Different applications are targeted.
• To have the best Bluetooth data reception, direct line of sight between 2 devices should be away from
ground or wall.
• BC840 is an ultra short range module for wearable applications.
• With larger PCB trace antenna, BC840M range is 400 meters at 125 Kbps. It can be used in a wide range
of applications, wearable, home automation, beacon, medical devices etc..
• Peak TX for BC840E with ANT060 is 15.38 dBm and range is measured at 3400 meters at 125 Kbps. It is
an ideal module for long range, battery powered applications.
• If one device must be installed closer to ground or a wall, install other devices far away from a wall or
ground.
• Indoor condition is different for different building. We suggest testing Bluetooth data reception in the
building with the worst case condition.
• B840 Series modules have compatible soldering pad footprint. Bluetooth range can be upgraded by
replacing module. No hardware change to the host board is required if your enclosure can accommodate
the longer module.

BC840 EvaluationBoard Schematics
BC840/M/E, Compact BLE 5, Thread, Zigbee Modules
Ver 1.00, April 2019
Evaluation board can be used as a reference design for using modules..
Suggestion for Battery Power Application
Standby current consumption is important for battery-powered product. We suggest adding a 32.768 kHz
crystal and 2 capacitors on host board. The 32MHz main clock won’t be active at idle state to save power.
Two inductors required for on-board DC to DC converter are inside BC840 and BC840M. You can enable
DCDC converter to have lower power consumption.
