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.

The following is a block diagram of Nordic nRF52840 Bluetooth Low Energy (BLE) SoC. Arrows with white
heads indicate signals that share physical pins with other signals.
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-310co-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 BT840F on the Host PCB
The following figure shows recommended mounting of BT840F module on the host PCB.
• For the best Bluetooth range performance, the antenna area of module shall extend 9.8 mm outside the
edge of host PCB board, or 9.8 mm outside the edge of a ground plane.
• The next choice is to place a module on a corner of host PCB, the antenna area shall extend 9.8 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 BT840F module in the middle of a host PCB.
For the best Bluetooth range performance, keep all external metal at least 30mm from the antenna area.

Host Board Design for Low Cost or Long Range
On nRF52 series SoCs, Nordic offers various memory options and protocol supports. Fanstel offers various
antenna and power amplifier options. A host board can be designed to accommodate these nRF52 modules.
Our suggestions for host PCB design:
If your main goal is minimum PCB cost,
• use a 2-sided PCB.
• Use library component from EV BT832 Gerber files, can be downloaded from
http://www.fanstel.com/download-document/.It has 16 castellated pins plus 24 LGA pins. BT840F library
component can be used. However, signal routing can be difficult on a 2-sided PCB.
• Be sure of no metal contact in the area of 21 additional BT840F pins.
• BT840F can be mounted on a BT832 pad.
If you main goal is maximum wireless range,
• use a 4 or more layers PCB.
• Use library component from EV BT840F V4 or newer Gerber files, can be downloaded from
http://www.fanstel.com/download-document/.It has 16 castellated pins plus 45 LGA pins.
• As much ground plane under BT840F, on top side of host PCB as possible. Use EV BT840F V4
Gerber files as an example.
• If your products may need wireless range of 1350 meters at 1 Mbps, allocate physical space for a
15x28x1.9mm module. This larger module size is required to accommodate Skyworks SKY66112
power amplifier.
• Don’t use P0.06 (BT840F pin B4), P0.17 (BT840F pin C3), and P0.19 (BT840F pin D2) on the host
board. These pins are used to control SKY66112 power amplifier.

4. BT840F Evaluation Board
Communicating with a PC
A quick and easy way to evaluate BT840F is to use a PC as the host processor. Connect the development
board EV-BT840F to a PC with an USB cable. Then,
SetS1, BT840F is set to command mode. PC will communicate with BT840F.
Set switch S1 to the other position, BT840F is set to data mode. PC will communicate with a remote device
through BT840F Bluetooth wireless connection.

3. Portable smartphone charger can be used to power this board. The circuitry to the left of micro USB
connector, J16 produces periodic load to prevent portable smartphone charger from shutting down.
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 BT840F. You can enable DCDC converter
to have lower power consumption.
