I've been trying to setup a IR transmitter for ages. I'm running a RasPi B with the latest Raspbian lite.

I installed lirc and added dtoverlay=lirc-rpi,gpio_out_pin=23,gpio_in_pin=22,gpio_in_pull=up,debug=1 to my config.txt.

I really don't care about the receiver, I only need to be able to transmit signals.

If I try to irsend I get a hardware does not support sending error.

Here is the dump from the lirc service status. I've been trying to solve the error but with no luck.

  • What have you connected, and where? – Milliways May 26 at 0:31

    NOTE in latest update to Raspbian "Name: lirc-rpi Info: This overlay has been deprecated and removed - see gpio-ir" – Milliways May 26 at 0:40
  • @Milliways yeah, I read about that, however i can't find any clear docs, especially as I need a transmitter and not a receiver. Any link to docs/tutorials would be appreciated – Lorenzo May 26 at 11:13
  • I connected an IR led to pin 23 with a transistor, tho I don't understand what kind of hardware error I could be getting – Lorenzo May 26 at 11:15
