BLHeli and Passthrough Mode


I’m using BLHeli ESC’s and don’t have a USB linker. I know you can use passthrough mode if your autopilot supports it. I’m coding my own Autopilot using a RPi (don’t talk to me about the lacking of a realtime kernel, I understand the constraints lol).

I wondered if there’s a way I cancel use it without the linker. What exactly does an autopilot using passthrough mode do? I’ve read about people needing to do certain sequences upon first use in order to get their ESC working with Arduino boards, hoping a similar thing can be done with my ESC and Pi.


It seems my escs can be calibrated with min throttle then max. No need for other settings right now. May buy a linker in the future to configure. Thanks
