RPI 2, LIRC -> Sending KEYS

Ok, i am quite new to thhis forum (also to PI GPIO usage) but i think i tried everything i've found to fix the Problem ....

As described, i have a PI 2, Latest Updates und such are installed, Lirc is running (Recive works, send not)

I have build a few IR Transmitters to test different way's, but i cannot get Lirc to send Remote codes.

Here's my conf:

config.txt

# Uncomment this to enable the lirc-rpi module
device_tree_overlay=lirc-rpi
device_tree_param=gpio_out_pin=17
device_tree_param=gpio_in_pin=18
device_tree_param=gpio_in_pull=down

as said before, recive is not a problem, only sending with IR doesn't work, when i send some recorded
IR Signal the control LED only flickers very low.

I searched the forums, the net a few day's but i cannot find a soloution, has anyone here running LIRC
on tje RPI 2 with Reciving AND sending?

thx

You are not alone!

Here is another thread where a few people (including me) have the same problem: receiving works, sending does not. It worked on the RPi1, and it still works on the RPi1 with the latest kernel and the device tree.

This has been fixed with the latest kernel from rpi-update!

Ah yes, thank you, you are correct, now it works!

The output of "uname -a" now has "3.18.7-v7+ #756".
