Strategus Posted December 11, 2022 Report Share Posted December 11, 2022 Flirc USB adapter works when computer is connected to old Samsung monitor via HDMI, but stops working when PC is connected to oldish (dumb) JVC TV via HDMI. I got everything setup the way I wanted using a monitor on my desk connected to a Linux PC running Kodi. However, when I connected the same setup to my JVC TV set, the remote stopped responding. I need some suggestions as to how to proceed debugging this issue. Thanks. Quote Link to comment Share on other sites More sharing options...
Nathan Posted December 13, 2022 Report Share Posted December 13, 2022 If you plug a keyboard into this PC while connected to the JVC TV, does the keyboard also not work? Quote Link to comment Share on other sites More sharing options...
Strategus Posted December 13, 2022 Author Report Share Posted December 13, 2022 The attached keyboard works in both configurations. The Flirc shows up in both configs, but doesn't work connected to the TV. Bizarre! Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 002: ID 0e8d:0608 MediaTek Inc.

Nathan Posted December 14, 2022 Report Share Posted December 14, 2022 Can you run the Flirc USB app on the device and get the Device Log when connected to each monitor? I genuinely can't see how or why an HDMI connection would interfere with USB, so I'm curious to see if the USB is still registering input when plugged into the JVC TV.

Strategus Posted December 14, 2022 Author Report Share Posted December 14, 2022 Running Flirc connected to the desktop monitor does what I'd expect and key presses register: Tue Dec 13 2022 21:04:55 Flirc GUI Version v3.25.3 Operating System: Linux *** Device Disconnected *** *** Device Connected *** Firmware Version: v4.9.3 SKU: Flirc 2.0 [dori] Git Hash: 0xcb185bde <1>malloc_addblock(49): Heap Block: 0x20001A7C - 0x20003BFF (8k) :e:27665 ....remote key presses show....

Strategus Posted December 14, 2022 Author Report Share Posted December 14, 2022 The TV has a setting named "CEC". If that is set to "disable", we get the "too many edges" message. If it's set to "enable", that message goes away. Unfortunately, the remote doesn't work with either setting. Quote Link to comment Share on other sites More sharing options...

I'll ask Jason to take a look, but it may be a bit. With the Skip 1s getting ready to ship, it's been all hands on deck. Quote Link to comment Share on other sites More sharing options...
Strategus Posted December 14, 2022 Author Report Share Posted December 14, 2022 I appreciate your time and help. I'm anxious to get my hands on the Skip 1 myself. My Harmony is getting a bit dated. FYI. Just for grins I moved the Flirc over to a Pi 4 and tried the same experiment with the same result. I also tried different HDMI cables. I'd say just back-burner this for a while, maybe forever. If I have some epiphany I'll post back, but you needn't worry about it. Quote Link to comment Share on other sites More sharing options...

So regardless of the host computer, the TV is interfering with the Flirc? Reading some past replies with this issue, it sounds like what might be going on is some kind of IR bleed. For some reason light might be hitting your Flirc that the Flirc is interpreting as commands, so it can't see whatever remote you're using. Might try blocking your TV remote or, as a test, blocking off the Flirc with a paper towel or toilet paper tube or something while it's plugged, so the only thing it can see is the remote you're using to control it on the other end of the tube.

Strategus Posted December 15, 2022 Author Report Share Posted December 15, 2022 (edited) I turned on the TV and took the TV remote out of the room completely, and blocked off the sides of the Flirc with a paper towel tube. After powering on the PC, the remote (a Harmony 880) worked for a few seconds (5 or 10?) and then quit. I don't know. Poltergeists? With the clarity of hindsight, I brought the TV remote to my desk. The Flirc works just fine with the TV remote sitting next to the PC. Maybe I'll try painter's tape over the IR sensor in the TV. I dunno. Do IR receivers ever transmit "junk"?

Strategus Posted December 15, 2022 Author Report Share Posted December 15, 2022 I believe I've eliminated IR weirdness from the equation. I took the PC, my desktop monitor, and the keyboard/mouse into the room with the TV. First I powered on the PC and monitor (exactly as when on my desktop), and the remote control/Flirc worked perfectly. Next I powered on the TV and played with the TV remote. The PC/Flirc/remote continued to worked fine. This implies to me that the issue has something to do with the HDMI connection between the TV and the PC. Just to be clear, there was not a connection of any kind between the PC and the TV in this test. I wanted to see if there was IR coming from the TV perhaps.

jason Posted December 17, 2022 Report Share Posted December 17, 2022 First hint was 'old' tv. Old TV's have a lot of terrible light noise, namely, they emit IR. And then I scrolled down and saw, 'too many edges'. So it's seeing a bunch of junk from your TV. Make sure flirc is not in the line of site of the TV. It's good underneath it, or behind it. Make sure you record and setup flirc without the TV on. Go in another room, format flirc. Then set it up again making sure you don't hit record and it ever says 'recorded successfully' without you actually hitting a key. Means you just recorded noise. You'll need to hit delete, and then wait for it to be 'seen' again. Or hit format and start again. Go into advanced and disable all built in tables you aren't using Let me know how that goes.
