  • [Strobe GPIO6 Issue] Can't trigger falling edge to activate external flash

Device: OAK-D-Pro-W-PoE
Firmware/SDK: DepthAI 2.25.0.0
Platform: Ubuntu 20.04 / Python 3.8

📌 Issue:
I'm trying to trigger an external flashing camera via the GPIO6 pin on the OAK camera (M8 connector pin 6). The flash is connected as follows:

M8 Pin 6 → Flash trigger (configured as falling-edge (NPN mode))

M8 Pin 7 → GND (shared with Arduino and Flash device)

My goal is to use the setStrobeExternal(gpioNumber=6, activeLevel=0) to produce a falling edge TTL signal (HIGH → LOW) on GPIO6 when a still image is captured.

any suggestions?

    Hi ZhengkunLi
    The STROBE is activate by the LEFT camera only. You shouldn't need setStrobeExternal. The STROBE is directly connected to the CCMs strobe output.

    Thanks,
