Hi i am abdul i am trying to control lg ac

this is data what i get from remote

}

BUT LG AC DID NOT GET TURN ON or OFF

CAN YOU PLEASE HELP ME ON THIS

LG REMOTE MODEL NO IN BACKSIDE IS :- AKB75415316

The data you captured indicates:

Mesg Desc.: Model: 2 (AKB75215403), ...

So try:

ac.next.model = 2; // Some A/Cs have different models. Try just the SECOND one.

same not working...

change this line only

ac.next.model = 1; replace with ac.next.model = 2;

Have you ever had the library successfully send a signal yet? I.e. control a device from a distance?

Have you followed the trouble shooting guide yet?

What is the output on the serial interface?

This is serial output what i am getting

on 2nd side i put receiver and this is data what i get in receiver

So it seems:

Real remote OFF: 0x88C0051 Library OFF: 0x88C0051

So, the OFF signal should work.

Real remote ON: 0x880094D Library ON: 0x880092B (assuming I'm understanding your data correctly, IS THAT CORRECT?)

It differs in the last 8 bits. e.g. 0x4D is 0x4 for the fan speed and 0xD for the checksum. 4 is Maximum fan, 2 is Medium fan. So that explains the slightly different ON codes.

So, I'm initially at a loss as to why it isn't working.

Have you tried sending/replaying the captured codes via sendRaw() & sendLG2() directly yet?

if sendRaw() doesn't work for replaying a message, it seems more like a hardware/circut/environment issue.
