Hi, I’ve a quad running (what I know isn’t) a Pixhawk 2.4.8, it is on firmware v4.0.2.
I’ve got a servo plugged in to aux 1 and a bec powering it. The transmitter switch is on ch 9. In the parameters I’ve set RC9_OPTION to 19 and SERVO9_FUNCTION to 28, as described in the docs (see https://ardupilot.org/copter/docs/common-gripper-servo.html). However, the docs also say to set a few parameters that are not availiable to me in Mission Planner 1.3.70 (including GRIP_ENABLE).
Using the transmitter switch, I get no response to the servo. But if I set SERVO9_FUNCTION to 1 (RC pass thru), the servo operates fine, as expected.
Is it possible to both have a manually triggered gripper (as I do with SERVO9_FUNCTION at 1) and a gripper that can be triggered in the flight plan by DO_GRIPPER? If so, what parameters do I need to set?
