Turning on/off power to the GoPro

On the GoPro I have the opposite issue as with the LED. I'm able to issue the command to turn the GoPro On (GoPro button) - but it has constant power - i.e. there is power on the CAM PWR connector at all times, even if I issue the command to toggle the power.

Any ideas/suggestions - could the shield be faulty or have I messed something up..?

    I've tested this using a multimeter to measure voltage at the CAM +/- connector. There is always power, while the LED +/- connectors can be switch on/off using the 5 serial command.

    After adding a jumper to J9 to turn on diagnostic LEDs the blue D2 led is on - indicating GoPro power.

    You should be able to remove power completely from the camera. If you look at the schematic of the controller board, you'll see the CAM_POWER signal which turns a mosfet on and off. Issuing the software command should cause this signal to toggle. (likewise for the LED). It's possible the P-channel mosfet is bad or maybe the software is behaving properly. You could unplug the Arduino from the controller board and manually cause CAM_POWER to go high and low and verify BATT is being enabled/disabled.
