Ok will do this please also please have in mind that the signal is 56khz..maybe my emitter is 38khz!i took it out of a remote control!

OK

I checked out some of your signals and the captures don't look great. I tried several of them and they look inconsistent.

Capture the ON/OFF signal again, but keep the remote about 1m away from LearnIR pointed directly at the onboard IR receiver, for the best result.
Capture the same signal about 10 times and send them to me, for review.

No The IR LED does not have a frequency per se. The MCU generates the carrier frequency.
The emitter operates at a 940nm wavelength. If you took it from a RC, then it is the correct wavelenght. The IR LEDS used in night-cctv cameras are not the correct wavelwngth.

It is only the IR receivers that are specified with a carrier frequency.

Hi,
I am attaching the capture requested. As mentioned on my previous emails i have no problem sending the codes captured with the IRlearner back to my STB using the IRLearner module.The problem that i am facing is when i try to send the captured codes back to my STB using the ESP8266.
Regards

please try out this signal, which I had on file & may match your system (???)

sendir,1:1,1,58000,1,1,54,57,36,72,18,36,18,54,18,54,18,54,18,54,18,54,18,54,18,54,18,108,18,54,36,54,18,54,18,54,18,4715

should be for power toggle

OK That would suggest the software on the ESP or the emitter circuit or both.

Try again using the newer signals as they seem a bit better.(set of 10).
Also try using sendGC and sendRAW.....leave about 5 seconds between repeating the signal (not 2 secs)
=>delay(5000)

If that does not work, try removing one of the 10R resistors, and if that does not work try going back to the 5V circuit you had.

PS: gone for the night now :) zzzzzzzzzz

Hi,
I have an update for you. Further to your comment's about capturing again the signals with IRLearner from a 1 Meter distance it seems that my STB is responding much more better. I will performed further testings and come back to you with an update.I would like once again to thank you for your great patient through out this troubleshooting. Wiring still remains the same as the last one send with the 2 resistors
Regards

Hi, tested everything and its o.k now. The commands are send to the STB with sendGC
Thnks
