Basic networking with RIOT and Lua

What?

This application contains 3 lua modules:

• repl: provides the interactive shell.
• riot: Access RIOT system functionality. Currently, the only function provided is shell() for running shell commands.
• socket: Provides bindings for sock. Only udp and ipv6 are currently supported.

Example session

main(): This is RIOT! (Version: 2018.07-devel-1311-g8f5e6-batman-lua-library-temp)
Using memory range for Lua heap: 0x5667f2b0 - 0x56688ef0, 4 bytes
This is Lua: starting interactive session
