AWS Getting Started Guide

3.3 User Provided items

RJ-45 connection or NB-IoT/Narrow band WAN connection is required for the device to reach

global network.

In case it is RJ-45/Ethernet connection to ISP router/any other uplink router – an ethernet cable

connection must be provided to the unit (device has x2 100 Mbps Ethernet ports).

In case it is NB-IoT/Narrowband WAN ISP connection, you will need:

1) IOT NB/LTE-M SIM card (SIM card that supports IOT NB/LTE-M connection);

2) External antennas for the Narrow Band modem and GPS. Not provided with the package.

3.5 Additional Hardware References

KNOT can publish MQTT messages to AWS. The message itself can be a KNOT’s report –

message with the general information about the device, like model name, serial number,

RouterOS version, current CPU, used memory, free memory, and up-time.

Or, you can use the KNOT with additional hardware, like Bluetooth tags (that can be positioned

around the KNOT’s Bluetooth range). Bluetooth tags should be able to broadcast Bluetooth

advertising packets over advertising channels 37, 38 or/and 39.

KNOT’s Bluetooth interface is able to receive the tag’s reports and display them in the device’s

GUI. Tag’s reports are usually broadcasted in the HEX format. The KNOT can be scripted to

publish the tag’s reports via MQTT to AWS broker/servers.

Once the payload is displayed on the server - the published HEX payload can be deciphered into

an understandable format. The HEX’s payload (that was reported by the tag) will contain

information about the tag, like for example, its temperature at the moment of the report (if the

device has a temperature sensor) or its acceleration – movement (if the tag has a built-in

acceleration sensor).

You can use any vendor Bluetooth tag, as long as the tag supports advertising over Bluetooth

advertising channels 37, 39 and/or 39.
