Notice
The receiver defaults to the BUS protocol (The non-invert signal). When using F3 and F7 flight controller, it can be switched to SBUS protocol (The invert signal) by entering the command in BF CLI (step 3 of the binding tutorial). When using F4 flight controller (F4 flight controller does not support to switch signal type by entering command on CLI), if there isnt respond in BF receiver page when the receiver binding with remote controller successfully, please press the binding button to switch the signal protocol after the receiver power on. After short pressing the binding button, the red or blue light on receiver will flash 3 times. Blue light flashes 3 times means the receiver is on BUS protocol (original default setting), the red light flashes 3 times means the receiver is on SBUS protocol (which can be supported on most of F4 flight control).Please re-power the receiver afther switching the protocol then the red/blue light on receiver will flash 3 times to show the current protocal.
