Roku 2nd generation IR code brute force - Help test unknown codes?

[Rexypoo]

I pulled several IR codes off of my remote, and I found a source suggesting that Roku IR codes consist of one byte of data, along with the bitwise complement of that data (this appears to be correct for the codes I’ve identified).

I wanted to find IR codes for things like YouTube and AppleTV, so I wrote a Julia script to step through all 256 codes and help record the results. Most of them make a “dink” or “badink” sound and don’t seem to do anything else, but I found a few codes that show the message “Something went wrong. Please wait a few moments and try again.”.

Can anyone help test these codes? I suspect they might be related to CEC control of the TV, but my TV doesn’t support CEC.

I’ve attached the relevant .ir files, including the one with all the channels I found (US region).

Other findings: with current Roku firmware, only 128 of the 256 codes are used. When you cross the 128th code, the codes repeat, so the uppermost bit is ignored.

After my own heart. I did the same thing with my Fire TV. I went through about 65K codes. I’ll take a look at your codes and see what happens when I get a chance.

Brute force Fire TV IR codes

Before anyone tells me I’m an idiot like someone on another forum implied… Fire TV can use Bluetooth or infrared as long as they have an IR receiver. According to FLIRC you can even add a USB IR receiver. I don’t know if my codes work on all the Fire TV devices. I’ll put a couple code in here if anyone wants to test it. Just received my Flipper zero and decided to start small so I began with IR. I wrote a python script that outputs a file format meant to replace the tv.ir universal remote f…

I’m going to have to dig out an old Roku. I tried on my Roku TV and none of your codes work. I’m also messing with Bad USB on my Fire TV. Have you looked at Flipper IRDB? You should contribute your codes when you are ready.

I found a “Roku Remote” mobile app, which claims to work over WiFi and IR. Here are captures.
