Oppo blu-ray player not responding (error during the sequence) - FIXED

Having an issue with the Oppo integration (by henrikwidlund) in that it causes an error ‘error during the sequence’ wherein the Oppo player does not respond but which also causes the sequence to terminate.

I did recently upgrade to the latest version which is v0.0.20 but I also did recently upgrade the UC3 software to the latest beta build v2.8.4 as I was trying to see if it could fix some other minor issue I was having. The previous combination of Oppo integration v0.0.12 / v0.0.11 (can’t remeber exactly which) and UC3 software v2.8.3 was working.

  • integration is succesfully installed and I can see the various commands being available to select to include into an activity
  • am using these integration files labelled ‘unfolded-circle-oppo-v0.0.xx-remote.tar.gz’ and not the ones with ‘linux’, ‘macos’ or ‘windows’ in its filename
  • command tested is to power the Oppo on and off
  • have tried other versions of the Oppo integration (from v.0.0.11 to v0.0.20)
  • have tried both the ‘media player’ and ‘remote’ entities
  • am unable to downgrade the UC3 OS (have toggled the beta switch off and did a factory reset of the remote)

Am I doing anything stupid?

Should I be using the media player commands or the remote commands?

Can anyone with an Oppo blu-ray player with a working integration say what integration version and remote OS version they are using?

These are the relevant log entries: (‘disc’ is the name of the activity)

  1. I have the full logs of it would help.

Ah, was able to roll back the firmware from the beta v2.8.4 to the stable v2.8.3

Unfortunately, no difference. Really thought it would have fixed the problem :frowning: Really odd, as it worked before …

Issue sorted. Thank you to the integration developer henrikwidlund for suggesting the solution :slight_smile:

Unplugging the Oppo for several minutes got it responding to the remote again. Developer said that sometimes the network stack on the unit gets in a bad state and it has to be power cycled.

I’m using the integration as well, and seeing sluggish responses to button presses, and sometimes non-responsiveness. I’m wondering if the network stack issue is the cause. I’m also wondering if it would just be simpler to move to IR control.
