  1. The sock.allowedinterfaces property refers to the Wi-Fi interface as "WLN" and PPP — as "PPP". Sock.targetinterface and sock.currentinterface properties rely on the pl_sock_interfaces enum, whose members differ depending on the platform.
  2. Surrounding board hardware dictates which GPIO lines must be used as inputs and which — as outputs.

Supported Objects, variable types, and functions

  • Objects:
    • beep — generates buzzer patterns(1)
    • bt — in charge of the BLE (Bluetooth Low-Energy) interface(1)
    • button — monitors the MD (setup) line
    • fd — manages the flash memory file system and direct sector access(1)
    • io — handles I/O lines, ports, and interrupts
    • pat — "plays" patterns on up to five LED pairs
    • ppp — accesses the Internet over a serial modem (GPRS, etc.)
    • romfile — facilitates access to resource files (fixed data)
    • rtc — keeps track of date and time
