I am looking to test some discrete infrared hex codes I found on this forum to power off my Humax Freeview Aura box. Is there a simple way I can copy and paste the hex codes and beam the IR code to my Humax box from my WIN10 laptop to test the codes and try and find the correct code?

I don't mind buying a cheap USB IR dongle if that's what's required. I'm in the UK so it would be nice to find something local if possible.

Many thanks

Steve

Thank you for your reply but what do I search for on amazon. What is the device name?

Also what software will I need?

Thank you for the link, I have been searching for some free simple software to work with this device and let me paste in some hex IR codes then send them from my laptop to test them. It would also be nice to be able to learn some IR commands from a remote to the laptop.

I have also looked at IRToy and IRWidget but can't find any in the UK to buy.

Any ideas?

Another approach is GlobalCaché. These units are supported by a number of control systems or you can use them raw to learn and test codes.

For software, I recommend IrScrutinizer [Link: github.com] (disclaimer: I am the author). It supports a few different hardware, among others the previously mentionen GlobalCache, IrToy, IrWidget (captures only). However, I would recommend this: [Link: harctoolbox.org] . Hope you are able to build it.

Thanks, that looks like the solution, I will order the parts now and have a go at building one.

I received the components to build the Arduino Nano IR board, before assembly of the components on the board I decided to first flashed the firmware as detailed in the guide ([Link: harctoolbox.org]). At first I had a problem getting the firmware to flash, until Barf advised me to try changing the baud to 115200 which work a treat.

Photo of finished board -
IR-Hardware

I am now undergoing a learning curve for IrScrutinizer. I tried exercise 1 & 2 in the help file and all was working okay.

I can learn/teach an IR command from my Panasonic remote (i.e. power toggle) and analyse it ok. But when I press transmit the LED's on the board flash but the TV will not power on or off. I believe the SFH4544 & SFH4546 IR sending LED's are connected correctly (as I see a small infrared receive LED flicker on my old Media Center PC receiver when I press transmit in IrScrutinizer).

I have tried the same thing with different remotes on different devices but I'm having no success. I'm sure I'm missing something obvious.

Any ideas?



Many thanks

Steve

Probably a hardware problem. Can you see the IR light with an digi-cam (smartphone)? Most smartphones (not all!) can "see" IR light, cf.
[Link: en.wikipedia.org] (the photo).

I learnt something new again as I didn't know a camera can see IR. Looks like it won't work with an iPhone as it has IR filter. However it works with the camera on my PC and I can see two white lights on the IR Hardware so its sending something.

In IrScrutinizer I have the Output set to -

Pronto Hex (I also tried RAW but it didn't make any difference.)
Analyzer number basis 16

This is what was captured (which is a Panasonic TV power toggle command)

"This cannot happen!"

Everything looks fine. You can turn on "verbose" (under Options), shoot the signal, and post the output in the console window.

You can also try setting "count" on "Sending hw" to, say, 3.

Here [Link: hifi-remote.com] is a thread on IR sensitive (and not IR sensitive) cameras.

Thanks, I looked at your link which say the front camera should see the IR on my iPhone (I have an iPhone X) It does show up with the front camera but the IR LED does not show up a bright and prominent as my PC camera.

I now set the count to 3 and the debug output after verbose switched on is -

Does anyone know I can trouble shoot and fix this problem as I'm stuck?

I swapped out the two IR LEDs but still no good

Thanks

You can be pretty confident that the IR transmission works. No need to swap IR LEDs.
Please try with another device to convince yourself.

So it is probably some quirk in the device. Is it this thing: [Link: uk.humaxdigital.com] ? The webpages says

* The Humax Aura remote control supports both infrared and Bluetooth connectivity.
* Your remote is already paired with your recorder via infrared. During the initial set up process, we will guide you to pair your remote via Bluetooth.
* The remote LED will flash Red when paired via infrared and Green when paired via Bluetooth.

so there appears to be an error potential.

If using the original remote, can it control the thing without eye contact?

Yes the box I want to control is that Humax Aura in your link. However I haven't tested the IR learning and sending with that box. I decided to test it with a simple IR Panasonic TV and a simple IR air conditioning unit without success. The previous debug download posted is with the Panasonic TV
