Libero has created a protocol which is “open” to our customers only. Our clients get a “license” to use it.
The protocol is fully documented
The protocol does not rely on any (black-box) SDK or hidden/obscured API’s
The protocol is not limited to a specific operating system
The protocol is not limited to a specific hardware architecture
The implementations of the protocol can be generated, automatically, for a large number of programming languages (This eliminates potential implementation bugs and reduces time-to-market).
The protocol compilers (used to generate implementations) are completely open source
Our own reference and demo applications use the exact same protocol, anything we can do, the customer can do.
The protocol is not limited to a single transport (It can be transported via TCP, MQTT, WebSockets, HTTPS, GATT, etc…)
The protocol can be encapsulated for integration into other systems or to add additional levels of security (by using AES/RSA or AES/ECC for example)
The protocol can be upgraded to support new features while fully maintaining backward AND forward compatibility
In comparison with for example a welknown supplier of other suplliers of screens or (LED-)systems :
Their protocol is not documented, as they aim to keep it secret.
Using their devices requires the use of closed source, black-box binary SDK’s.
Their SDK’s target a limited set of operating systems and some require the user to disable some of the security features of the OS to work
Their SDK’s target a limited set of hardware architectures, most notably x86/64 and ARM (Android only)
Their own applications have access to features not available to customers
Their SDK’s require the use of specific programming languages (C/C++/C# for Windows, Java for Android)
You have to trust that their black-box binaries do what they say they do and nothing else
Examples of languages that are supported: C, C++, C#, F#, Java, Python, Go, Ruby, JavaScript, TypeScript, Objective-C, Swift, Kotlin, PHP, Dart, Rust, Haskell, etc…
