Issues with RF Remote w/ IR Learning Feature (Odroid C2)

1st Official Post

    Hi all,

    Searched far and wide and wasn't able to find a solution for this.

    I recently purchased this remote:

    https://www.amazon.com/gp/product/b01n0suuzs/ref=ppx_yo_dt_b_asin_title_o01?ie=utf8&psc=1

    It works great out of the box with LE 9.0 and the IR learning worked fine for powering on TV and Receiver.

    Where I am having issues is powering on the C2. I tried to run IR Learning to capture my harmony remotes power signal that has worked in the past, but the IR learning feature of this remote can't catch it for some reason.

    Reviewing other threads I am seeing mentions of Lirc and ir-keytable, but neither of these would seem to fix my issue. Since I tried turning on the listening for my remote via ssh, when I press the programmable IR button on my remote, my C2 doesn't capture anything. So I don't have a code I can use to update my config file.

    Is my only hope buying an HK Remote and hoping my other remote can learn from it or should I return this remote completely and look elsewhere?

    Thanks in advance!

    ir-keytable needs to be listening on the right protocol to see anything and some remotes have odd vendor invented stuff for power-on events; for the same reason you might not be able to teach a remote that only understands specific protocols and doesn't just capture/record whatever signal is transmitted to it. I'm about to start playing around with the current official HK remote to ensure it works on mainline kernel images using mainline u-boot, but that's not an endorsement and might not be a quick solution.

    Are you implying that if I were to buy the HK remote, that my MX3 variant would still not be able to learn it?

    I am about to buy that remote, but I won't if it's not 100% sure that it work.

    I've boot tested a C2 running the AMLGX (mainline kernel) image and from tonight or whenever the next balbes150 image gets pushed the HK remote works OOTB including power on/off (i've added device-tree keymap configuration and a kernel driver for the HK remote this morning). I have no idea about Harmony compatibility but it's a standard NEC protocol device so it probably isn't a big challenge for a learning remote.

    Thx Chewitt,

    To anyone having the same issue in the future, the only way to program a RF remote with IR learning is to buy the odroid remote. It should capture that signal fine. Worked for me.
