We create effective end-to-end #InternetOfThings projects for startups and enterprise clients.

Last but not least, a big kudos to our developers Mirek Prýmek and Daniel Beseda, who worked on the project furiously in the last few months.

Bisquitt wouldn’t have been possible without you!

And to learn more about Bisquitt and its features, have a look at its GitHub repository.

This was just a brief summary. If you’d like to learn more about the story behind Bisquitt, go read our blog post.

We intend Bisquitt to be the best and most widely used open-source MQTT-SN gateway.

We plan to invest into its development a lot in the coming months and years. We also plan to follow the development of MQTT-SN 2.0 and add its support to Bisquitt over time.

[Energostack Engineering @energo_eng]

Bisquitt highlights include:

• Support for most MQTT-SN 1.2 features
• Support for DTLS 1.2
• Authentication extension based on MQTT-SN 2.0 draft

[Energostack Engineering @energo_eng]

So, after some deliberation, we decided to write our own gateway and open-source it, so that others can benefit from our effort.

And this is where we are now. Welcome Bisquitt!

[Energostack Engineering @energo_eng]

When we started playing with MQTT-SN at Energomonitor, we tried to look for one. We ended up disappointed. We found several projects, but all were incomplete, unmaintained, or just didn’t work

[Energostack Engineering @energo_eng]

This all sounds good, so what’s the catch? Well, you need to connect the MQTT and MQTT-SN worlds together. This can be done using a gateway, which translates between the two.

[Energostack Engineering @energo_eng]

So what protocol should you use in this case? If you already have existing MQTT infrastructure, the best choice is MQTT-SN. It maintains MQTT semantics but works on top of UDP. This means you can keep your application-level protocols mostly unchanged.

[Energostack Engineering @energo_eng]

This is not an issue if your device uses a permanent network connection or connects via GPRS/LTE. But it becomes a problem if you use networks such as NB-IoT, which only support UDP. And you want to use such networks – especially for battery-powered devices.

[Energostack Engineering @energo_eng]

If you’ve ever had anything to do with the IoT world, you’ve probably encountered MQTT. It’s the standard protocol used to communicate with IoT devices. It’s used by millions of them.

But it has one problem — it works on top of TCP/IP.

[Energostack Engineering @energo_eng]

We’ve just released Bisquitt, a transparent MQTT-SN gateway, as an open-source project.

Why did we develop it? What features does it offer? And why are we excited about it? 🧵

Nothing makes us happier than the positive impact of the projects we are part of. This factory has been saving more than 35% of its consumption and 3 480 tonnes of CO2 per year👏Check out this Case study.
