I found an article here :(Link to the article) entitled "LoraWAN and IOTA: Proof of Concept of storing data in real time in the Tangle".
The thing is not clear to me is that if IOTA has been installed on a small device supports LoraWAN (https://lora-alliance.org/about-lorawan) in this proof of concept? (You can see an example of this small device here: Link to the device.)
And if so, which version of IOTA (which language?) this version? : https://github.com/iotaledger/iota.js ?
And if so, does it mean that it is possible to install a JavaScript version of IOTA on a small device supports LoraWAN? Because usually we need to run a C/C++ code on a device such as small devices support LoraWAN and apparently there is no version of IOTA implemented in C language in its official Github repository (https://github.com/iotaledger).
Or maybe in this proof of concept, IOTA has been installed in another more powerful device (which device? it is not clear to me.)
Am I right? What is my mistake?
Thanks
