3 Bluetooth Modules with Amplifier, BT8X and BT8XE Ver. Aug. 07. Introduction BluNor BT8X is powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using Nordic nrf8 SoCs. With an ARM Cortex TM MF MCU, available KB flash, 6KB RAM, embedded.ghz multi-protocol transceiver, power amplifier, and an integrated antenna or an u.fl connector for external antenna, it allows faster time to market with reduced development cost. The following is a block diagram of BT8X. Antenna circuit, MHz main clock, and.768 KHz sleep clock are integrated. Three GPIOs are used to control SKY66 power amplifier. The other 9 GPIOs of nrf8 can be accessed from main board. Connection to an external NFC (Near Field Communication) antenna is provided. BT8X Block Diagram A high performance PCB trace antenna is integrated on BT8X. An u.fl connector on BT8XE provides connection to an external antenna.

5 Bluetooth Modules with Amplifier, BT8X and BT8XE Ver. Aug. 07. 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 nrf8 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 nrf8 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 nrf Series SoCs. All nrf 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: S: 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 nrf Series devices. nrf DK board is recommended for firmware development. Nordic software development tools can be downloaded from the following webpage. nrf_dev_kit.html&cp=_!

7 Bluetooth Modules with Amplifier, BT8X and BT8XE Ver. Aug. 07 The bit ARM Cortex MF 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 0-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 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 +0dBm down to - dbm in db 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

AT Commands AT command firmware is available for BT8X. Brief description of AT commands Each command line consists of a prefix, a body and a terminator. All command lines begin with the prefix AT (ASCII 06, 08) or at (ASCII 097, 6). The body is a string of characters in the ASCII range 0-. Control characters other than <CR> (carriage return; ASCII 0) and <BS> (back space; ASCII 008) in a command line are ignored. The terminator is <CR>.!

16 Bluetooth Modules with Amplifier, BT8X and BT8XE Ver. Aug. 07 There is no distinction between upper-case and lower-case characters. A command line can have a maximum length of 80 characters. It is automatically discarded if the input is longer. Corrections are made AT command is case-insensitive, following /r/n for end code. The default baud rate is 9600 one stop bit and no parity Command mode When P0.0 of nrf8 (pin 6 of BT8X) is pulled high, it is set to AT command mode.

Communicating with a PC A quick and easy way to evaluate BT8X is to use a PC as the host processor. Connect the development board EV-BT8X to a PC with an USB cable. Then, Set S, BT8X is set to command mode. PC will communicate with BT8X. Set switch S to the other position, BT8X is set to data mode. PC will communicate with a remote device through BT8X Bluetooth wireless connection. Docklight is a testing, analysis and simulation tool for serial communication protocols (RS, RS8/ and others).

20 Bluetooth Modules with Amplifier, BT8X and BT8XE Ver. Aug. 07. Bluetooth Line of Sight Range Measurements Test Conditions We use evaluation boards EV BT8X and EV BT8XE 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. 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 0 o for total measurements. Measurement results Ranges between two BT8X boards are average of 6 pairs of Master-Slave boards. BT8X antenna is not omni directional. Range at worst case angle is 060 meters and at best case angle is 0 meters. Average range is 70 meters. BT8XE with external antenna ANT060 is omni-directional. Range is 0 meters between two BT8XE boards for all directions. When BT8X is used with a BT8XE with ANT060, it is almost omni-directional. Ranges are between 7 meters and 0 meters for all angles. When tester lift the second stick, Bluetooth range is slightly longer.!0

21 Bluetooth Modules with Amplifier, BT8X and BT8XE Ver. Aug. 07 When BT8XE is used with a + dbi antenna (instead of ANT060 at +6 dbi), Bluetooth range increases from 0 meters to 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.!
