Trying to work out how to calibrate esc’s when I cannot connect using only usb power. It would appear that FC cannot be powered this way.
Can only connect to Betaflight (or computer) with battery plugged in is this normal?.
Because I can connect with battery plugged in I know it’s not cable or drivers.
In blheli I have “program by tx turned off”
I want to calibrate because motors don’ always start at the same time. Running Oneshot125.
