we develop a healthcare solution where we want to connect the devices to Ethereum-Blockchain.
The software development on the devices is done low level. There is no operating system like Linux or Windows running.
By my understanding to send/receive Ethereum transactions we need to create own RAW SSL TCP/IP packages to forward them to an additional server where they can transferred to an Ethereum-JSON Package and forward to Ethereum.
I'm not sure, if this the right way how to connect an external device to Ethereum (IoT<->Ethereum) or if there is a better and more secure way to do it?
I would be happy about any comments about this topic.
Thanks & Best Regards
