Integration Manual

switch and tilt switch, which is closed when the antenna end of the board is pointed down and open
otherwise. Three pins on the SHNSM are supplied for Segger J-Link device connection to the
microprocessor.
3.3 Operating Specifications
3.3.1 Input Power
 3VDC, 10 microamps most of the time, 150 mA for 150mSec every 1 second
3.3.2 Operating temperature range of the equipment
 Outdoor commercial temp range - 0 to 70 degrees Celsius
3.3.3 Classification
 Portable
3.3.4 Number and types of i/o ports and associated cables
 30 ports on CPU, no cables
3.3.5 RF Parameters
3.3.5.1 Transmit frequency(s)
 2.4 GHz transceiver
 -90 dBm sensitivity in ANT mode
 -93 dBm sensitivity in Bluetooth low energy mode
 250 kbps, 1 Mbps, 2 Mbps supported data rates
 TX Power -20 to +4 dBm in 4 dB steps
 TX Power -30 dBm Whisper mode
 13 mA peak RX, 10.5 mA peak TX (0 dBm)
 9.7 mA peak RX, 8 mA peak TX (0 dBm) with DC/DC
 RSSI (1 dB resolution)
3.3.5.2 Number of Channels
 40 channels, 2MHz separation, 2402MHz - 2480MHz
 3 Advertising channels, at 2042MHz (channel 37), 2426MHz (channel 38) and 2480MHz
(channel 39)
 Remainder are Data channels (channels 0 - 36)
3.3.5.3 Type of Transmit: Frequency hopping, spread spectrum / digital modulation system / fixed
 To mitigate interference in such a crowded band, BLE uses frequency hopping. Three RF
channels are dedicated for advertising functions that allow the discovery of devices available
in the vicinity. Upon a connection request, the same channels are used for initial connection
parameter exchanges.
 Once a device is discovered and connection is initiated, regular data channels are used for
communication
3.3.5.4 Transmitter Power output
 0 dB
3.3.5.5 Antenna type
 PCB trace
 No other antenna shall be used.
3.3.5.6 Transmission Duty cycle
 While advertising, every second or so
 While in regular mode (after connection) whenever data needs to be sent
