Comment on Raspberry Pi 2: LIRC with an active-low IR-receiver with raspbian Jessie by Tianming

Thank you so much! I was trying to get my IR receiver to work with LIRC on Raspberry Pi Zero W, but I couldn’t get anything from mode2, except when I plug in or pull out the receiver from breadboard. After reading your post and adding “dtparam=gpio_in_pull=up” to /boot/config.txt, it worked!

Everything used to work fine on my Raspi3 with stretch. Suddenly it stopped working, maybe it was because of the kernel update in december 2017..
Anyhow, I’ve also added the “dtparam=gpio_in_pull=up” to config.txt and now everything is working fine. OMG, thanks!!

Thank you so much for taking the time to post this – I spent hours trying to get my TSOP1136 working before I came across your page and now with the dtparam to apply an internal pullup it’s working sweetly.

Thank you so much Patrick! You saved my day. I just added “dtparam=gpio_in_pull=up” to /boot/config.txt and it worked on my Raspbian Stretch distro.

In reply to Stephen Mann. Try to use the mode2 tool to check whether anything is captured on the pins assigned to the lirc-receiver.

I am having a heck of a time getting LIRC to work on Jessie. Could you share some code to get me going? I want to have a Pi Zero send IR commands to my TV and STB as part of my home IOT. But first, I need to capture the existing remote’s IR codes.

Comment on Raspberry Pi 2, Raspbian Jessie and WiFi vs. Ethernet at boot-time by Patrick

In reply to rodymary. If the RPi gets an 169.x.x.x address it means it has not discovered a DHCP-server (the one who assigns IP-addresses in an IP-network). I assume that when you connect the RPi via an Ethernet cable in the same network and other WiFi-devices are working well. So most likely, even though the RPi could connect to the WiFi using Wheezy it wasn't able to communicate with other devices. Have you checked the log-files? In /var/log/syslog or by running dmesg? Maybe there are some messages giving you some clues. Have you tried your Edimax adapter on a Laptop or a PC? Try to make sure that it works. What do you use as power supply? Maybe the RPi is not able to power correctly your USB-devices and thus gives this strange behaviour?

Never succeed with RPi2B + edimax dongle + fresh Jessie install + apt upgrade, to make wifi working 🙁
SSIDs are well displayed and I’m abble to select one of them and key my password in, but RPi never connect, even with the conf you mentionned.

So I tryed Wheezy and that’s just a little better as the wifi logo is now displayed, and I am probably connected, but not with an automatic local IP my routers DHCP should give me. Usually i’ve got something like 192.168… and here RPi has 169…. ?

Maybe you can help me… thanks a lot (i’m a real noobs in linux and rpi world)
