RDP is a protocol we created specifically for Roastmaster that allows any processor-equipped circuit board to send temperature data directly to Roastmaster iOS.
Historically, Roastmaster has relied on 3rd party manufacturers to produce both the hardware, as well as the software API that Roastmaster would use to communicate with that hardware. If those APIs contain bugs, or didn’t function correctly, there was nothing that could be done with Roastmaster to resolve it.
RDP was specially designed for Roastmaster, and is now built directly into Roastmaster’s code. Anyone can use RDP on virtually any hardware. This removes the reliance on 3rd party vendors, and lets anyone design and build a probe host for very little cost that can easily communicate with Roastmaster using this flexible protocol.
It’s also fully open source, and published and publicly documented under the permissive MIT license, which means it’s free to use by any individual or manufacturer, whether for personal or professional adoption.
A protocol is really nothing more than a language two entities agree to “speak” in order to communicate with each other. If you speak English, you can understand the information in this article because you understand the English language. English is, essentially, the “protocol” of this article.
The same is true with software. As long as two applications or devices speak the same “language”, they can talk to each other and share information. Since Roastmaster now “speaks” RDP, any circuit board with a CPU and WiFi capabilities can be programmed to talk directly to Roastmaster using the language of RDP.
We get endless inquiries about whether Roastmaster supports roaster brand X or roaster brand Y. Chances are, we’ve fielded questions for your brands of roasters. The answer, of course, is always (regrettably) no, because this has relied on Roastmaster and the roaster speaking the same language.
This has been a frustrating barrier that we are pleased to have finally removed with RDP. RDP can be implemented in your roasters for a tiny cost per unit, and offer out-of-the-box compatibility with Roastmaster. Users would have no configuration burden, or aftermarket mod’ing to perform–they would just unpack it and start capturing data!
Please, if you’re entertaining the idea of this, reach out to us. We’re happy to discuss the specifics with you.
A “probe host” is required to send readings to Roastmaster. A probe host is comprised of the hardware required to gather the data, and simple software to interpret and send this information over WiFi to Roastmaster.
A probe host can be a DIY project, based on a popular SBC (Single Board Computer), such as Arduino, Raspberry Pi, or Feather Huzzah. Or, it can be a professionally designed circuit board built in a roasting appliance, designed and coded by the manufacturer to provide out-of-the-box support for Roastmaster iOS.
Whatever the specifics, as long as it can run software, read a probe, and send those readings as UDP packets over WiFi, it can be used to communicate those readings to Roastmaster iOS.
The hardware of a DIY probe host is comprised of three elements.
The software running on the processor of the probe host reads and interprets the thermocouple voltage, builds a simple JSON packet according to the rules of the RDP protocol, and sends that string as a UDP packet across the WiFi network, where Roastmaster is listening and receives it.
First, you must assemble the hardware. Yes, this will probably require a soldering iron, and some basic electronics knowledge. It is not, however, and advanced project.
Once you have hardware, it’s just a matter of obtaining or writing simple software to read and interpret the thermocouple voltage signal, generate the RDP network datagrams, and send them to Roastmaster over WiFi.
Complete documentation is available in the RDP Datasheet. It includes explanations, examples and best practices for creating your own software, or tweaking software available on forums or Github.
I am hopeful that users will embrace this protocol in the spirit of open source, and share their work, so that soon there will be a repository of software for different devices to help folks get started building their own probe hosts.
In the mean time, we’ve already created a sample software sketch for the Feather Huzzah board and Max 318555 amp board on GitHub. Feel free to download, and modify it to suit your needs.
Well, iOS has grown quite a bit since Roastmaster came to the store a number of years ago. It has matured greatly, and we’ve done our best to make sure Roastmaster has followed suit. As iOS has grown up, though, much of Roastmaster’s core code and user interface has stayed the same.
Through the years, Apple has deprecated much of the original iOS framework, especially with regard to the User Interface. The remaining legacy code, though viable, has become very dated compared to the shiny new framework code that has adorned the last couple of iOS releases. These new frameworks take much of the burden off of developers when coding for a growing number of devices and screen resolutions, and let us focus effort on more important aspects of our software.
When you couple that with the plain ol’ fashioned improvements in programming languages themselves…it was time for a rewrite. We had discovered, to our dismay, that we spent too much of our time designing and programming fragile interfaces with legacy frameworks, that stood the risk of breaking when a new device hit the market.
Roastmaster deserves better. We needed to bring the code to a state where our time was spent on features and functionality, not interface buttons, switches and graphics. We take joy in adding new capabilities, not implementing device support for the newest iPad screen sizes.
So, we made it happen. Roastmaster for iOS 10 is the end result of 7 long months of complete code overhaul. The interface was re-imagined and re-implemented. The workflow, in many places followed suit. Every interaction that you, the users, have with Roastmaster was a candidate for the chopping block, if a better, more efficient way was conceivable. Everything from iconography to typography has been improved, with one goal in mind–a better experience for you (well, us), the users.
And, even with all of this going on, we managed to pack a ton of great new features into this update as well!
We sincerely hope you enjoy the new interface, workflow and functionality. This was a very long beta testing period, since the battle-tested legacy code was stripped out, and the potential for bugs was high. We’ve already had some great feedback on the new version, and welcome any more that you may have.
This release is dedicated to Aaron. Your keen mind, logic and input was invaluable to Roastmaster, as was your friendship to me. Glide high my friend!
Roastmaster for iOS 9 is available for download from the app store!
You had ideas and we set to work…we had ideas and we kept going! What emerged is a brand new Roastmaster, with a host of new features aimed at streamlining any workflow, but especially geared toward serious specialty coffee roasters and anyone who has a serious passion for nothing but the best possible coffee.
The job of software is to make your life easier. Nobody likes extra work, and the new features in Roastmaster are designed to eliminate as much of that as possible. We want to help free your attention–letting you be more focused on your coffee, not on software details.
With automatic bean lot tracking, curve events, advanced reporting, inline calculators, inventory reminders and a host of other features, this version is geared toward speed, efficiency, and most of all, to unlocking the hidden information of your beans, vendors, roasts, cuppings. Quality is key…and we want to help you achieve it!
The Range probe has been discontinued and will no longer be supported in future versions of Roastmaster
