LIRC, IR LED is turning on but devices not responding

Sun Apr 23, 2017 5:30 am

Finally got LIRC to work, verified that the LED lights up when "irsend SEND_ONCE /home/pi/tvon.conf KEY_POWER" is sent, but unfortunately the signals are not getting to the devices. Tried to record, and re-record a couple of different devices/ config files but neither of them turned on or off. I put the LED right next to the receiver on the devices as well to confirm it wasn't a range issue. Sort of at a loss here now though, not sure what steps to take to try and make sure the IR codes are correct since I've already recorded them twice with the same results. Hoping someone can steer me in the right direction.

Purchased these: https://www.amazon.com/gp/product/B00EF ... UTF8&psc=1
and I essentially hooked them up using this wiring: https://cdn.instructables.com/F04/OYYA/ ... .LARGE.jpg

Tried switching it from 3.3v to 5v too and still nothing. Also hooked up my Arduino with an IR receiver and put it in front of the IR LED after running irsend SEND_START /home/pi/tvon.conf KEY_POWER and the receiver lights up so the signal is definitely getting out, its just not translating to my AC or TV for some reason. Receiver stopped responding once I had it about a foot or so away from the LED, but again, I put the LED right up to the TV and it did nothing. Thanks for any help.

Try sending the code twice or three times in a row, sometimes the receiving device needs to receive the command multiple times (error checking).

I tried that and unfortunately didn't work either. did the "irsend SEND_START" command and the LED blinks but no go on turning anything on. I was reading that some LEDs (for some odd reason) might not be compatible so I shot for this https://www.amazon.com/Infrared-Shield- ... B01C2AQL62 to see if it might work. Sort of bummed because it doesn't seem as though this would leave any other GPIO pins up for grabs so I might have to have two home-assistant setups since I have an RF Tx/Rx setup on there already. Thanks for the reply though :D

By the way, just out of curiosity, this is how I have the IR LED wired, does this look correct? http://imgur.com/UgXeAgW

I'm glad its working. Maybe a problem with the wiring or the IR LED, hard to guess without knowing the exact components you used.

How did u managed to get it to work?
Mine IR led is working when holding it close to the tv, but if i'm going further away from the tv, the signal won't reach the tv anymore.
