Hi everyone, The recent ArduSub 4.5.5 release includes some changes to how some of the autopilot’s PWM outputs (SERVOn_FUNCTION parameters) and joystick buttons (BTNn_FUNCTION parameters) are configured, to make things more customisable and hopefully less confusing. In particular: Affected de…

[image] Eliot: We’re also working on a further ArduSub update to try to automatically transfer old configurations to match the new one after a firmware update Noting that ArduSub 4.5.6 stable is now available, which automatically updates old output function configurations to use the new param…

Hi. I updated BlueOs to the new stable version and updated the firmware to 4.5.5. Gripper, Tilt, Lights do not respond. I’m at a loss. I’ve attempted to downgrade firmware, and Os, and QGC. Nothing seems to fix. Is there a solution to this. The ROV is a brick at this point. thank you.

Hi @cam1 , welcome to the forum :slight_smile: Sorry to hear you’re having issues. Could you confirm your currently running QGC, BlueOS, and ArduSub versions, as well as the hardware you’re running on, and which output pins your lights, camera mount, and gripper are connected to? It could also be …

QGC 5.0.6 BlueOS version 1.4.2 Ardu Sub 4.5.5 I believe the output pins on the navigator board are as follows ( i may be incorrect though) 16 tilt - yellow / red / black 15 gripper - white / red / black 11/12 lights - yellow

[image] Cam: 15 gripper - white / red / black If this is a Newton Gripper then that wouldn’t have been controllable before this update (the servo_n_* joystick button functions only worked for pins 9/10/11), but I’ll assume you’ve identified your connections correctly. Can you make sure you …

Thanks for that. I’ve attempted to adjust the parameters. None of the values suggested (actuator, lights ) exist in the list of options. I’ve attempted to reload 4.5.5 and bluerov heavy parameters into Blueos. Now when i enter Vehicle setup i get a message that 0/0 parameters are loaded, and no para…

Hi @cam1 - You’ll need to enter in the numerical value (in parenthesis) under autopilot parameters, for the parameters Eliot listed. You may need to click force as Eliot mentioned! If no parameters load at all, try restarting the autopilot from the power button in the lower left of BlueOS….

Thanks. I managed to get things back functional…..kind of. Lights, Tilt, Grabber are working. Still unable to access parameters in BlueOS. Made adjustments through QGC. Updating BlueOS and Firmware to 4.5.5 crated all sorts of problems. Hopefully Blue Robotics can create a more user friendly update …

Hi @cam1 - Sorry for the frustration. Can you share what version of BlueOS you updated from / too? The issues described here are only due to Ardusub 4.5.5, we anticipate things to get much more intuitive in the future…

i updated BlueOs from 1.1.0 . I have attempted a test flight. Nothing is functioning as it should ( including all the telemetry - depth hold / stabalize mode). All thrusters had been working and everything before and after the update had been calibrated. The BlueROV2 heavy that i have is completely…

Well with 2 full days of troubleshooting. Managed to Get things back up and running. The ROV is functioning ( most importantly video / and stabilized flight modes). Still working on lights and gripper. I can at least complete my survey work. Its unfortunate that Blue Robotics are so incredibly slow …
