HD-PVR IR Blaster setup

Post by rwiskow » Mon Nov 21, 2022 4:50 pm

Has anyone had success getting the IR blaster in the HD-PVR 1212 working with current LIRC?
I've been running a mythtv system for over 10 years, and I decided it was time to upgrade the server hardware. I was running Ubuntu 16.04 with MythTV 0.28, which had lirc 0.9.0. I was able to use the lirc_zilog driver with the HD-PVR to handle sending IR codes.

The new system is Ubuntu 22.04, with MythTV 0.32. So far I was able to get everything migrated and upgraded, but then I ran into the usual pain point of getting the IR blasting to work. The lirc package is now 0.10.1, which changed the configuration. There's now a lirc_options.conf file, and hardware.conf is no longer used. So the wiki page /wiki/Hauppauge_HD-PVR is out of date.

I've added the modprobe option to enable the irblaster ("options ir-kbd-i2c enable_hdpvr"), and it does recognize the device and creates /dev/lirc0 as expected:
[72288.062734] ir-kbd-i2c 4-0071: Zilog/Hauppauge IR blaster firmware version 2.1.0
[72288.062749] Registered IR keymap rc-hauppauge
[72288.062849] rc rc0: HD-PVR as /devices/pci0000:00/0000:00:1d.7/usb1/1-8/i2c-4/4-0071/rc/rc0
[72288.063066] rc rc0: lirc_dev: driver ir_kbd_i2c registered at minor = 0, scancode receiver, raw IR transmitter
[72288.063115] input: HD-PVR as /devices/pci0000:00/0000:00:1d.7/usb1/1-8/i2c-4/4-0071/rc/rc0/input484
[72288.106979] hdpvr 1-8:1.0: device now attached to video0

The next hurdle was that the packaged setup of lirc was specifying the "devinput" driver. I changed this to "default" and set the device to "/dev/lirc0".
But now when I try to do an irsend, I get a "transmission failed" error:
irsend SEND_ONCE blaster 0_4_KEY_POWER
irsend: command failed: SEND_ONCE blaster 0_4_KEY_POWER
irsend: transmission failed

There's a little more detail in the syslog:

That's where I'm currently stuck. Does anyone have any tips for getting this working?
I'd be perfectly willing to downgrade back to lirc 0.9.0, but haven't had much luck with that either. If anyone has information on how that can be done, I'd try that.
Has anyone gotten a simple RS232 IR blaster to work with lirc 0.10.1? I think I've got enough stuff in my parts bin, I could quickly solder something like that together if it's actually a viable option.
