transmission failed Error running command: Input/output error.

[Carccha]

Hi, I'm on Raspbian Buster. I checked and applied all of the recommandations. I can record remotes but when I test to send a IR Signal I've got -> transmission failed Error running command: Input/output error.

/boot/config.txt: dtoverlay=gpio-ir,gpio_pin=18 dtoverlay=gpio-ir-tx,gpio_pin=17

/etc/lirc/lirc_options.conf driver = default device = /dev/lirc0

Have you any idea ?

Hi @Carccha,

The configurations seems fine. After changing device to /dev/lirc0 have you started/restarted the systemd service for LIRC?

sudo systemctl start lircd

or:

sudo systemctl restart lircd

Best regards, Leon

Hi Leon,

Yes, I followed step by step the instructions in the pdf update. I precise, I've got this issue with a new installation of Raspbian Buster

I will retry this evening.

Kind Regards.

Hi Leon,

I reinstall from scratch my RPI V3 with Raspbian Buster. I have to install python3-setuptools in addition of all packages.

When I send: irsend LIST tv "" I've got: 0000000000000000 KEY_POWER

And When I send: irsend SEND_ONCE tv KEY_POWER I've always got: unknown remote: "hifi" Error running command: Input/output error

Hi @Carccha,

Please note that in chapter Setting up LIRC of the user's manual python3-setuptools is part of the packages that have to be installed during the first step for the chapter Install dependencies. It is actually the last package in the long list of dependencies.

Having 0000000000000000 in the lircd.conf means that the scanning of the remote control was not successful. Please scan the remote control again with LIRC by following the steps in section Using IR LED: https://github.com/AnaviTechnology/anavi-docs/blob/master/anavi-infrared-phat/anavi-infrared-phat.md#using-ir-led

Best regards, Leon

I redo the procedure with the same issues.

In syslog, here we've got:

According to the log "this remote configuration cannot be used to transmit", probably because of the 0000000000000000 value you mentioned in your previous post. This is not an OK value for a button so please switch to /dev/lirc1 and scan again the remote control with irrecord. You need to have properly scanned remote control to proceed successfully with irsend.

Best regards, Leon

Leon,

After some research here

I add the following lines to /etc/modules file lirc_dev lirc_rpi gpio_in_pin=18 gpio_out_pin=17

And it's finally works. Maybe that helped someone.

Thanks for your help and your time. Kind regards.

Hi @Carccha,

Thank you for the feedback. I have a look at the user's manual and add your feedback about /etc/modules to it.

Thanks, Leon
