This quick start guide is intended for use with Laird Connectivity’s Sentrius™ MG100 + BT610/BT510 IoT Starter Kit and the hardware therein. This starter kit is perfect for prototyping a wide range of IoT applications such as cold chain monitoring, AC current sensing, tank monitoring solutions, and more.

Gather data from the BT610 I/O sensors and BT510 sensors and aggregate it with the MG100 before sending it up to the cloud utilising Software AG’s Cumulocity IoT platform. Leverage this platform to visualize your data utilising pre-built dashboards, providing instant access to actionable data and offering a critical path to scaled deployments.

Architecture Description

The MG100 device is configured to use LwM2M and DTLS with pre-shared keys. LightweightM2M (LwM2M) is a protocol that runs on top of CoAP.

LwM2M is an ideal protocol for NB-IoT or Cat-M1 (Applies to Pinnacle 100/MG100 only) because it is UDP based. When using NB-IoT on the MG100, we do not recommend using the TCP protocol due to the network latencies inherent to NB-IoT.

A LwM2M Server (Cumulocity IoT) is used to display information about the MG100 device and discovered sensors.

Supported sensors are:

  1. Sentrius BT610 I/O sensors
  2. Sentrius BT510 sensor (temperature data only at this time)
  3. Sentrius MG100: onboard temperature sensor (LIS3DH)

The software version, model, manufacturer, serial number, and current time can be read. In addition, the green LED on the MG100 device can be turned on and off using the light control object. If BT510 and/or BT610 sensor advertisements are detected, then their sensor readings will be interpreted and sent to the server as well.
