Question

Latest SDK for RUT955 - RUT9_R_00.07.03.1

The lua files in this SDK have been passed through luac so are now bytecode rather than plain text.

As this is supposed to be an development kit, was this optional encoding a mistake?  

Will future SDK releases have bytecode or plain text lua files?

Cheers.

Answer 1

Hello,

The change to byte code was intentional.

The reasoning behind was to save memory and protect software developed by Teltonika.

The GPL in the latest SDK is intact, as open source files are still available. The SDK itself still allows users to create users their own software for Teltonika hardware.

Best regards,

So do you have documentation to interact with those lua modules?

Also some of the luac files in the SDK are modifications on files licensed under "Apache License 2.0" which are intended for open source projects.  For instance file package/feeds/vuci/api-core/files/usr/lib/lua/vuci/firewall.lua which in previous SDKs bears the header
