Hello. I purchased IoT Node and IR remote module from you at Maker Faire. I have a question about the IR module. Should I call setReception() method, if I only send IR message, or is it just functional when using IR reception?
It’s OK to call setReception() method only if you’ll be using the infrared receiver module. The setReception() module basically configures the hardware timer on ESP32 to decode infrared signals. You don’t need to call it if you don’t need it.
