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 nRF52832 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 nRF52832 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: S132: 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. http://infocenter.nordicsemi.com/index.jsp?topic=/com.nordic.infocenter.nrf52/dita/nrf52/development/ nrf52_dev_kit.html&cp=1_1 !5 Bluetooth 5 Modules with Amplifier, BT832X and BT832XE 3. Product Overview Ver 2.01 June 2018 Brief description of nRF52832 SoC is provided. For full description of the SoC, please download from Nordic Semiconductor website. https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy Block Diagram of nRF52832 The following is a block diagram of Nordic nRF52832 Bluetooth Low Energy (BLE) SoC. !6 Bluetooth 5 Modules with Amplifier, BT832X and BT832XE Ver 2.01 June 2018 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 +20dBm down to -4 dBm in 4dB steps. 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. !7 Bluetooth 5 Modules with Amplifier, BT832X and BT832XE Ver 2.01 June 2018 Mechanical Drawings The followings are mechanical drawings of BT832X.

You can use Nordic develop tools to develop firmware for many UNO R3 compatible shields. 3. SW5 must be set to OFF and use internal 32.768 kHz crystal or oscillator. 4. 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. !20 Bluetooth 5 Modules with Amplifier, BT832X and BT832XE Ver 2.01 June 2018 5. Bluetooth Line of Sight Range Measurements Test Conditions We use evaluation boards EV BT832X and EV BT832XE for range measurement. A portable smartphone charger is used to power each board. Bluetooth line of sight ranges are measured in Shen Zhen, China and Scottsdale, Arizona, USA. The Scottsdale test site is a better controlled environment. Except for dust blowed up by wind or drive-by car, it is relatively interference free. Each evaluation board is either loaded with Master firmware or Slave firmware. Each board sends a data packet out every second. When a valid data package is received, an LED toggles ON and OFF. Blinking LED indicates a valid data is received. We measure the maximum range between two boards that the LED is blinking. The first evaluation board is mounted on a stick. The antenna is on vertical direction and at 2.1 meters above ground. The second evaluation board is mounted on a shorter stick carrier by a tester. After each measurement, the second evaluation board is rotated by about 30o for 12 total measurements. Measurement results * Ranges between two BT832X boards are average of 6 pairs of Master-Slave boards. BT832X antenna is not omni directional. Range at worst case angle is 1060 meters and at best case angle is 1320 meters. Average range is 1170 meters. * BT832XE with external antenna ANT060 is omni-directional. Range is 1350 meters between two BT832XE boards for all directions. * When BT832X is used with a BT832XE with ANT060, it is almost omni-directional. Ranges are between 1347 meters and 1350 meters for all angles. * When tester lift the second stick, Bluetooth range is slightly longer. !21 Bluetooth 5 Modules with Amplifier, BT832X and BT832XE Ver 2.01 June 2018 * When BT832XE is used with a +12 dBi antenna (instead of ANT060 at +6 dBi), Bluetooth range increases from 1350 meters to 1352 meters. Conclusions and suggestions for deployment * For the best range performance, antenna shall be vertically mounted. * For omni-directional performance, at least one external antenna should be used in point to point deployment. * In mesh network, an external antenna shall be used in each Relay node for omni directional performance. * Mounting one or both antenna higher above ground and far away from physical objects can increase range. * Our measurements are for clear line of sight. Range is reduced with plastic enclosure or with metal part nearby. * External antenna ANA060 is panel mountable and with plastic cover. !22 Bluetooth 5 Modules with Amplifier, BT832X and BT832XE Ver 2.01 June 2018 6.
