LG l9 II - IR Blaster not working with remote control apps - LG Optimus L3 II, L5 II, L7 II, L9 II

Hello. I have a problem... When I press any button on the remote control, IR blaster does not flash. When I run an application that comes with the system, IR blaster normally blinks, I checked so I pointed the other phone in IR blaster, and I started the camera. The camera can see IR, and no eye. I tried a variety of applications, and is always the same problem. What could be my problem?

The only application that can actually work with the IR blaster of your device is the built-in one. LG made this so no other application can be used for the IR blaster....( at least as far as i know )

It doesn't work because the creator of this rom change IR file(because 99% of roms for this phone are based on Vacain's kernel and device tree, so Varcain had customize the IR file) and it is a system app you can't use an other one, only the official with specific drivers can work.

Ir remote with peel

I have a problem with my ir remote. Trying to use my tv with the preinstalled app peel smart remote, it's not working. I've teste my ir remote blaster with *#0*# and it's working so it's not a hardware problem, the led is blinking, but using the smart peel app there is no light on my led and i can't control my tv or anything else. Please help me with some suggestions, tips, tricks...

Try to uninstall the updates.
After that try again if works.
For me the latest version of peel remote doesnt work.
I have done exactly that before i saw your reply. And it really works right now. Thanks anyway.

IR Jack (Jakcom IR)

Hello,
I've bought a IR Jack from AliExpress and I've downloaded ZaZaRemote to control it, but I'm not able to make it works. I think that the problem is that it can't find the correct mount point
Any of you has ever bought a IR Jack???
How did you make it work???
Thanks for help
Edit: I've tried with a Sony Z5 Premium and it's working, so probably the problem is that the application can't find the correct mount point
That device appears to be an iPhone accessory and requires a special app to control only on iOS. The app you have appears to be just a regular IR remote app for phones that have a built in IR emitter like many Samsung or LG phones.

Thanks for answer, but in on of the reviews review I've read about someone with a Sony that was able to use it. Anyway the application is supposed to work with every remote emitter, not only built in, I've seen videos in which they use it with a Jack IR

IR Blaster

I have tried many noms and almost all apps from the playstore and I can't seem to get my ir blaster working. It was working on miui
Which app.? Try peel.

Ir remote learning

Is there anyway to enable remote learning in redmi note 3 through it's ir blaster.

Not possible, I'm afraid. Our phone (just like the majority of smartphones) only has a IR sender and not a receiver.
So it can only send commands through the IR blaster but cannot receive commands from remote controls, for example.
What are you trying to control via the blaster?

Has an extensive list of supported devices plus it's free.

Can the IR blaster in face unlock be used as an IR remote?

Since the kernel sources are available I am guessing it might be possible eventually? Someone mentioned in a post that remote IR blasters just work at higher frequencies, so if the hw on Poco supports then.. yes??

less do itt! xD
its front notch has an IR camera, IR emitter, normal camera, earpiece and proximity sensor. the IR emitter could (very likely in theory) be used like an IR blaster. Has anyone tried installing Mi Remote on their Poco F1?
the review page (6) on gsmarena says it has an "IR blaster" but that's probably a typo : (cant post links because this is my first post on XDA altough i've been lurking here for a few years without reg)
ot: please tell me if call forwarding works for anyone natively on the google dialer app when you have lineageOS

I did try installing the latest Mi Remote from playstore having the same doubt/hope.
Unfortunately, it says that the installed device does not support MI remote due to lack of IR blaster. Alternatively, it says you can use the remote via a common Wi-fi network. So I guess it doesn't work.

There must be a way to force it to use the IR blaster, just as you could reroute it to the screen, it just needs something to output 1s and 0s, on and off
Yes you can !!

Either you need a Node MCU or an arduino with a Bluetooth module. So it can act as a gateway between your phone and locking system, thereby you can easily communicate with your HOME LOCK (only for digital locks :silly: )

when i installed Mi remote from playstore i got an error message saying "your phone can't control IR Devices ,You can control Your Mi Tv /Mi box using WiFi !!"
Have a look at this thread

You can use a solenoid or actuator for an extra locking bolt , controlled by a cheap WIFI on/off switch
It has ir camera nit the emitter. Every living thing in this world emmits IR waves which it captures. Hope everyone understands.

I get it, but no. Look up a couple Pocophone reviews on Youtube, some of them spend some time on the IR unlock. If they have video of it working in the dark you'll see a light red flash across the person's face. There is also an IR emitter in the phone. Of course, it would be awkward to point things with the way it's placed but it beats having to buy and bring with you everywhere a dongle with emitter.

That's IR wave l. Beacuase we dont emmit is uniformly. Some place have high intensity and some have low intensity
Actually it's not possible since, the frequencies are not the same, the ir receiver in your tv should not be able to see those that are emitted by your phone. There's a lot of infrared wavebands and the ir emitter doesn't emit on the right one, and you can't change it unless you change the emitter.

I mean you see the line shine from the phone over the person's face like a scan.
But here is a screenshot of the keynote :
(I think I attached it correctly, not sure)
EDIT: and you see "infrared lighting" well that's the emitter.

Actually I'm wrong since the light emited by the blaster is visible to IR detectors (just tested with my Honor 7 ir blaster/receiver) ... So it may be possible, imagining that we could control with enough precision the IR led. May be a good idea to ask to a kernel maker if it could be possible.
OffTopic : Mdr pas courant d'avoir des reunionnais sur xda c vrai xD
Interesting idea
I'd make an app if I knew how to...

Atleast the people are taking the idea seriously now, with enough activity maybe it will catch someones devs eyes and he would push the matter.
Forgot this whole issue, i'l be on watch and post bavk here if I find anything.
I am very skeptical that this is possible. I don't think that the main problem would be a possible slight wavelength mismatch but the needed led modulation frequency. You see, the IR code is not simply encoded by a different pattern of long and short IR pulses but that pattern is superimposed on a high carrier frequency. When the led is 'ON' it's really pulsing on and off usually 38,000 times a second. This is something that's easy to do in hardware but difficult to do in software, specially if you are not running a real-time-OS (don't think that this linux kernel is).
It would be much easier to build a separate wifi->IR gateway.
