[Issue] Communication timeout while printing S10

[Keelan-Moore]

Hi there!

I am new to the Octoprint world, very excited about how it will change my workflow but am getting issues with blobs and pauses accompanied by the following in the serial logs:

Communication timeout while printing, trying to trigger response from printer. Configure long running commands or increase communication timeout if that happens regularly on specific commands or long moves.

My setup:

• BIQU B1 SE Plus running standard firmware from their github. They do have their configuration, if its necessary I can upload here.
• Samsung Galaxy S10 - not rooted. Turned off all battery optimisations I could find, increased screen time to be on maximum (only 15 minutes).

• Shielded data USB cable (with tape over the power pin just in case).

  Things I've tried:

  • Literally every baudrate. I read that maybe that could cause it, in the config I believe its set to 115200, which is the default octoprint finds when I set it to AUTO
  • Turning the camera server on and off. I read a forum post about camera resolution slowing things down
  • ArcWelder plugin on and off
  • Manually keeping the screen alive the whole print
  • 2 different USB c hubs, and a simple usb c adapter
  • Unshielded and shielded USB cable
  • Turning of all over electronics in the room except the printer
  • Using a very simple model, vase mode cylinder
  • Using safe-mode, no change

Things I haven't tried but not sure if its necessary, please let me know if I should:

• Flashing to most recent version of Marlin - the default BIQU firmware is from Aug 2021. The serial buffer size is set to 4, and I read I could improve quality by increasing it to 16?
• Maybe rooting the S10, I've never done it so I'm concerned but maybe there is a further battery saving setting Samsung is hiding??

I'm sort of out of ideas and would really appreciate any help! I'm attaching the system info bundle which includes the whole serial log showing the error

Just a quick update!

I tried installing Octoprint on my laptop (mac) and it worked flawlessly so I believe the problem isn't the buffer size on the printer firmware, the problem is somewhere on my phone
