Integration Manual

 Every second it sends out battery information (a few bytes of payload)

3.3.5.7 Device Duty cycle

 Sleeps most of the time

 Wakes up every 100mSec or so to keep BT connection alive

 Wakes up asynchronously when event(s) happen as part of device function

3.4 Mounting

For best RF performance, place the SHNSM at the edge of the target board with a margin beyond the

target board as shown below.

Keep any metal parts at least 10mm from the antenna area of the SHNSM board.

4 Software

The SHNSM firmware consists of three portions: the Bootloader, the BLE SoftDevice and the application

firmware. The Bootloader and the BLE SoftDevice are provided by the microprocessor chip producer,

Nordic Semiconductor (www.nordicsemi.com). The application software is specific to the application. It

monitors the sensor outputs on the SHNSM and sends and receives BLE messages using the SoftDevice.

The Bootloader may be used for DFU OTA (Device Firmware Update Over The Air) application software

updates using the nRF Toolbox app on a mobile device or custom software.

Firmware application software updates may also be performed using Segger J-Link device connected to

the three pins on the SHNSM.
