|
|
To enable transmit functions define IR_TX_PIN
|
|
To enable receiver functions define IR_RX_PIN

MQTT messages
|
|
--------------------------------------------------------------------------------
|
|
|
|
Decoded messages:
|
|
|
|
Transmitting:
|
|
Payload: 2:121944:32:1 (<type>:<code>:<bits>[:<repeat>])
|
|
The repeat value is optional and defaults to 1
|
|
|
|
Receiving:
|
|
Payload: 2:121944:32 (<type>:<code>:<bits>)
|
|
|
|
Raw messages:
|
|
|
|
Transmitting:
|
|
Payload: 1000,1000,1000,1000,1000,DELAY,COUNT,FREQ:500,500,500,500,500
|
|
| IR codes | | IR repeat codes |
|
|
codes - time in microseconds when IR LED On/Off. First value - ON, second - Off ...
|
|
DELAY - delay in milliseconds between sending repeats
|
|
COUNT - how many repeats send. Max 120.
|
|
FREQ - modulation frequency. Usually 38kHz. You may set 38, it means 38kHz or set 38000, it meant same.
|
|
Repeat codes is optional. You may omit ":" and codes. In this case if repeat count > 0 we repeat main code.
|
|
|
|
Receiving:
|
|
Payload: 1000,1000,1000,1000,1000
