Hi, i have got same problem try everything that came into my mind and cant manage to work.
I am unable to turn on my AC Fujitsu
I am sure, that my system can send ir signal (tested and it works on my tv).
What i can receive from IRDump2 is raw data code for powerOn and other settings.
uint16_t rawData[57] = {450,450, 500,450, 450,450, 450,450, 450,450, 450,450, 450,450, 450,450, 450,450, 450,450, 450,450, 450,450, 450,450, 450,450, 500,450, 450,450, 450,450, 500,1300, 450,450, 450,1300, 500,1300, 500,450, 450,1300, 450,1300, 500,1300, 500,1300, 450,1300, 450,450, 450}; // UNKNOWN 68979EDA
Then i try to re-send with:
irsend.sendRaw(rawData, 57, 38);
Code is same every time, my device is 5-10 cm from AC unit so distance is not a problem.
Signal is send every 5 second, but device do not response.
Please HELP !!!
