2. Codes Development Using Nordic Tools
Development tools by Nordic and other third party development tools recommended by Nordic should be used.
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.

Ver 1.11 May 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.
The following cryptographic features are provided.

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 or more, 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 in BT832X, BT832XE, BT840X and
BT840XE.

below.
A firmware example to control Skyworks SKY66112 power amplifier is below. This firmware file can be
downloaded from http://www.fanstel.com/download-document/.
You can set nRF52840 TX to up to + 8 dBm. The conditions for passing FCC and Industrial Canada
certification testings:
•
BT840X: Set nRF52840 TX to +2 dBm.
•
BT840XE: Set nRF52840 TX to +2 dB and use Fanstel antenna ANT000.

4. Bluetooth Range Measurements
Bluetooth range measurement reports and hex codes used in measurements can be downloaded from
Bluetooth Range Measurements section of this webpage.
http://www.fanstel.com/download-document/
Bluetooth ranges are measured between 2 modules on evaluation boards for various height of antenna. On the
first measurement, both antennas are pointing to sky and facing each other. The second antenna is rotated by
30 degrees clockwise after each measurement.
Bluetooth range is specified as the average of 12 measurements with the least significant digit truncated.
• 1.52 meters (60 inches) is typical height of thermostat in the USA.
• 0.55 meter (21.5 inches) is typical height of antenna if an IoT device is plugged into a wall AC outlet in the
USA. When USB840F USB dongle is plugged into a smart phone charger plugging into a wall AC outlet to
collect Bluetooth sensor data or to be used as a Bluetooth signal repeater.
• Low Multiple Path Interference (LMPI). For longer range measurement, antenna must be higher to have
LMPI. To have LMPI, 60% clearance is required. For example, if transmitter and receiver is 1000 meters
away, both antennas must be 3.33 meters above ground and away from any obstruction.

Evaluation board can be used as a reference design for using modules. EV BT840F V4 is designed for the
BT840F soldering pads with 61 pins. These 21 pins in solid dark color are for BT840F.
EV BT840F V4 evaluation board is developed for BT840F and BT832X. It can be used for BT832 and BT832F.
Pins in solid color are used only for BT840F. Blue color pin names around U1 BT840(832) are for BT832/
BT832F/BT832X. Red color pin names are for BT840F/BT840/BT840E. Firmware pin configuration is required
for a host board to accommodate BT840F/BT840/BT840E and BT832/BT832F/BT832X.
Additional feature enhancements for version V4 evaluation board:
1. It has the same foot print as Arduino Uno R3. Additional connectors are added for connection to extra GPIO
pins of BlueNor modules.
2. EV BT840F is not an UNO R3 compatible board. You can use Nordic develop tools to develop firmware for
many UNO R3 compatible shields.

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.

7. Miscellaneous
Soldering Temperature-Time Profile for Re-Flow Soldering
Maximum number of cycles for re-flow is 2. No opposite side re-flow is allowed due to module weight.
Cautions, Design Notes, and Installation Notes
Failure to follow the guidelines set forth in this document may result in degrading of the product’s
functions and damage to the product.
Design Notes
(1)Follow the conditions written in this specification, especially the control signals of this module.
(2)The supply voltage has to be free of AC ripple voltage (for example from a battery or a low noise
regulator output). For noisy supply voltages, provide a decoupling circuit (for example a ferrite in
series connection and a bypass capacitor to ground of at least 47uF directly at the module).
(3)This product should not be mechanically stressed when installed.
(4)Keep this product away from heat. Heat is the major cause of decreasing the life of these
products.
(5)Avoid assembly and use of the target equipment in conditions where the products' temperature
may exceed the maximum tolerance.
(6)The supply voltage should not be exceedingly high or reversed. It should not carry noise and/or
