IDE : Arduino IDE

Issue

For any button click on my AC Remote, there are multiple outputs. And the protocol is Unknown, I'm not sure if I should be getting multiple set of outputs, for a single button click and how to transmit back to the AC.

ReceiveDemo output

Received noise or an unknown (or not yet enabled) protocol

Sum: 600

Received noise or an unknown (or not yet enabled) protocol

Sum: 3050

Protocol=PulseDistance Repeat gap=8900us

Space of 8900 us between two detected transmission is smaller than the minimal gap of 15000 us known for implemented protocols like NEC, Sony, RC% etc..
But it can be OK for some yet unsupported protocols, and especially for repeats.
If you get unexpected results, try to increase the RECORD_GAP_MICROS in IRremote.h.

I have also attached the output of ReceiveDump.
