Help with send ir command

[dantederrico]

hi, I have a problem with PiIR. I'm trying to copy the ir codes of a tv remote control and transmit them with raspberry. When I launch the command to record I can store the codes in the .json file but when I have to send them it doesn't transmit anything. I wanted to ask you if it is necessary to change something in the config.txt file (dtoverlay) or if it is not necessary. My configuration is the following: - - Raspberry Pi 2B bullseye

• ir board ENER314-IR

Thank you very much and I hope you can help me 😊

I don't think config.txt or other settings is necessary.

• Make sure your GPIO number is correct
• Use phone camera or something to see if the IR LED is flashing (on iPhone only selfie camera can see IR)
• Try LIRC or other project - if it works, and PiIR doesn't, report me again

I prefer to use PiIR because unlike Lirc it has less configurations to do. However in the past it worked I don't know what could have happened. Now I tried to install Buster on Raspberry pi 2b. From the setting in the photo I don't have to change anything? I would like to use PiIR possibly.

I don't know about gpio-ir. Maybe it's a LIRC thing?
PiIR doesn't need these either.

Hi Takeshi
I still can't transmit the IR codes of my TV remote control. I can store them in the json file but when I go to send them nothing happens. The LED on the transmitter card lights up and is therefore driven but I'm not sure if the LED transmits. I tried using a camera to see but nothing happens. I currently have raspberry pi 3B+ with bulleseye. Ir receiver connected to pin 22 while ir transmitter to pin 18. I'll leave you a short video. I hope you can help me. Thank you.

Could you send me the JSON file? I might be able to look into it.

Thanks for the support Takeshi, fortunately I solved it. I recharged the operating system and now everything is back up to work!! Thanks anyway for the support and I'll keep you updated if you have any problems 😊

Puoi mandarmi il file JSON? Potrei essere in grado di esaminarlo.

Hi Takeshi, I did a test today. I tried to get the project running on a rasperry pi 3b+ with bulleseye 2022 (32bit) installed. I captured the IR codes of my hifi device (Denon RC-220) again but they don't work... which is very strange because on the Raspberry Pi 2B with Buster I had done the same procedure and they worked. What can be changed? I don't understand why it works on 2b and not on 3b+. The codes recorded by the json file are the same. I used same hardware to transmit and receive. I'll leave you the .json file I recorded. I hope it can help me and who knows it might be useful to someone else. Thanks in advance as always.I'll also leave you the configuration file used by Lirc to send commands in case you want to make a comparison.

That JSON file is a bit unusual—it might be a bug in PiIR. Could you please try this: while recording into a new JSON file with PiIR, play your JSON file using PiIR to see if you get the same result? If it doesn’t, then it’s definitely a bug in PiIR.

Hi, I did the test as you told me. I re-recorded the buttons by creating a new json file but the recorded data is identical. But the Raspberry updated and it no longer works :(. Can you do some testing to get feedback? At the moment it only seems to work with that version. Thank you ^.^

Hi Takeshi, sorry for the inconvenience, it magically works on raspberry p 3b+ too (I don't know why maybe as you say it will definitely be a bug) I wanted to ask you a question. Since I created a voice assistant in Python, could you tell me how to integrate the send ir command (piir play...) into the script? because I'm trying but I can't thanks!!

[ts1]

I'm using in my script like below:

import piir
remote = piir.Remote(Path(__file__).parent / 'light.json', 17)
remote.send('full')
