After the Bluetooth packet is broadcasted by the tag and the KNOT captures it, you can utilize scripting and scheduling to structure messages out of the payloads that the KNOT receives and automate the KNOT to send those messages periodically via MQTT, e-mail or HTTP post. That means you will need a server where the data is going to be stored and visualized. In this guide, we will showcase a server called ThingsBoard and MQTT communication how to communicate with it using the MQTT protocol.

ThingsBoard has a cloud solution and different local installation options (on different OS). Since we've added a container feature, it became possible to also run the platform within RouterOS. For In order to do that, you will need a RouterOS device that has at least 2 GB RAM, a USB slot for the additional storage, and is either ARM64 or AMD64 architecture device, like for example, a CHR machine or a CCR2004-16G-2S+.

• 2+ devices with Bluetooth interface, like the KNOT (the amount of the devices required depends on the size of the area);,
• 1+ Bluetooth TG-BT5-IN and/or TG-BT5-OUT tags (depending on how many assets you need to track);,
• a running ThingsBoard server that is going to collect and visualize the data.,

just attach the tag to the asset that you wish to locate and afer few additional steps explained in the guide below, you will be able to track the approximat positon of the assetYou should be able to to track the approximate position of the asset that has the tag attached.

Summary

How is it going to work? Let's say, you have a warehouse...You can scatter the KNOTs across the warehouse so that the KNOT's Bluetooth range does not overlap with the neighboring KNOTs. You need to test the Bluetooth range in your environment/topology to figure out how far the Bluetooth range goes, as it can be much lower than expected if you have a lot of 2.4 GHz interference or materials that can impact the signal strength, like concrete. For example, in line of sight, with no interference, the distance at which the KNOT is able to capture the tag's broadcasted payload, can be up to 180 meters (KNOT — ~180 meters — TG-BT5-OUT). But you also have to keep in mind that with more distance, more packets will be lost on the way.
