that is a new one.

upload the route so I can take a peek:

Hey.. sorry.. been out of town but still having issues. I did get the device to reset via SSH with a Bash script chatgpt helped me make. It wipes out the existing calibration and gets the device ready to accept a brand new calibration.


cd /data/openpilot || exit 1

test -x ./launch_openpilot.sh || { ls -la; exit 2; }

pkill -f "launch_openpilot\.sh" 2>/dev/null
pkill -f "manager|modeld|controlsd|locationd|boardd|pandad|loggerd|logmessaged|camerad|sensord" 2>/dev/null
sleep 3

rm -f /data/params/d/LiveCalibration /data/params/d/CalibrationParams /data/params/d/IsOnroad 2>/dev/null
sync

nohup ./launch_openpilot.sh >/tmp/op_launch.out 2>&1 &
sleep 15

ps -ef | grep -E "launch_openpilot|manager|modeld|controlsd|locationd" | grep -v grep
cat /data/params/d/IsOnroad 2>/dev/null
ls -lh /data/params/d/CalibrationParams /data/params/d/LiveCalibration 2>/dev/null
tail -n 80 /tmp/op_launch.out




ps -ef | grep -E "python3 ./manager.py|modeld|controlsd|locationd|camerad|sensord" | grep -v grep
ls -lh /data/params/d/CalibrationParams /data/params/d/LiveCalibration 2>/dev/null
cat /data/params/d/LiveCalibration 2>/dev/null

sleep 20

ps -ef | grep -E "python3 ./manager.py|modeld|controlsd|locationd|camerad|sensord" | grep -v grep
ls -lh /data/params/d/CalibrationParams /data/params/d/LiveCalibration 2>/dev/null
cat /data/params/d/LiveCalibration 2>/dev/null



This put the C4 back into reset calibration mode and it worked fine for the rest of the day. However powering the truck off overnight and it was back in "Calibration Invalid" again.
I will try what you suggested and upload the logs for you.

Again, I have it on the factory mount just below the mirror and didn't move the device from one session to another. Also, the device seems to still be seeing other vehicles in the greyed out background, so it is doing stuff but just not actually doing it's job.
Would using another model help do you think?

Take pictures of all your settings in sunnylink and send them to me in a DM. This is a weird issue for sure, and could even be a bad tilt sensor in the device. I can help you work through it in DM, no reason to tie up the thread.

Hi Alan.. thanks for the quick response! I will ask the following publicly in case it helps someone else. But I can send you any data you want privately.

Re: This issue with BP4
Should we even bother now that BP6 is released? Should I just use this instead? How stable is the beta?

If you do want the logs, question:

I am not near the truck right now and there is no wifi. I can connect to it via Comma Prime, but it is saying all the uploads are paused waiting on wifi. Does Sunny Pilot not permit uploading via the LTE modem? If that is not the default behaviour, is there a way to make it so? I don't have wifi access in our parking deck at home.

The LTE hotspot is off when the truck is off.

When you're back at the truck take a centered pick of the entire front windshield.

just take the device inside and power it with a phone charger overnight to upload logs

What was the length of time between the date you placed your order and when you received it?

It was about 6-7 weeks I believe.

 

[steelersmb]

Do you have the lightning coupler?

https://bluepilot.dev/2025/08/15/canfd-installation-video-links/

I'm a bit confused about the coupler. The video says that if you are using a quick-release dock, you don't need to use the coupler. Where does the coupler connect to? I'm assuming you plug the coupler with the lightning end into the black piece with the USB C connector and then the long USB C cable into the Comma end of the coupler and then into the Comma 4.

We did sell some docks with an integrated coupler, but we ran out of those. Most everyone has an external coupler.

IPMA --> Harness --> Harness box --> Long USB-C (ODB-C Cable) --> Coupler --> Short USB-C Cable --> C4 Dock --> C4.

 

[chriserx]

Speaking of, how often do y'all encounter a harness or CAN error? Especially those that don't remove theirs. Just curious if it's expected or what.

Every time. It's expected. You need the resistor coupler to do stop the errors.

Edited to fix typo.

sorry, I meant with the coupler.

You shouldn't really see any. About 1/50 times i might get a quick error if the bootup sequence is a little wonky, but it always clears itself in a few seconds, and it's pretty rate.

Mine is never removed, I get one or the errors about every 2 weeks, made the dock worth every penny, plug and replug fixes it, just curious what could be the issue.

Check for loose USB connection?

Which BP version are you using? With the earlier BP 3.0-BP 4.0 versions I would get occasional random radar errors that required a quick slide off the dock and back on to reset. With BP 5.0 and now on 6.0-beta, those errors all but disappeared. Are you getting the orange screen "take control immediately" error while driving, or the startup errors on the instrument panel of the Lightning?
