UNIHIKER Expansion IR

Use this skill when the user asks to send IR code, read IR code, or self-send and self-receive IR data on a DFRobot UNIHIKER Expansion board (SKU: DFR1216). Chinese name is 行空板扩展板.

Run exactly one bundled Lua script with lua_run_script.

If script execution returns an error, report that error directly to the user. Do not retry with changed arguments in the same turn unless the user explicitly asks.

Tool Call Inputs

Send one IR code only:

{"path":"{CUR_SKILL_DIR}/scripts/ir_send_get.lua","args":{"mode":"send","data":305419896}}

Read one IR code only:

{"path":"{CUR_SKILL_DIR}/scripts/ir_send_get.lua","args":{"mode":"get","timeout_ms":2000,"poll_interval_ms":100}}

Self-send and self-receive in one call:

{"path":"{CUR_SKILL_DIR}/scripts/ir_send_get.lua","args":{"mode":"send_get","data":305419896,"timeout_ms":2000,"poll_interval_ms":100}}

Recommended Flow

1. Confirm the expansion board is connected to the expected I2C bus.
2. Use default I2C settings unless the user explicitly provides custom wiring.
3. Use mode = "send_get" when user asks for self-send/self-receive in one operation.
4. Run {CUR_SKILL_DIR}/scripts/ir_send_get.lua with resolved args.
5. Report script output directly to the user, including any error.
