Frequently Asked Questions

Q: Can this receiver bind with a transmitter module from XXX brand?

A: The ELRS project is open-source, so any transmitter module using the ELRS protocol, regardless of brand, can bind with the receiver, provided the following three conditions are met:

The frequency must be the same (both 2.4G or both 915MHz).

The firmware versions must match. For example, if the transmitter module is running firmware version 2.5.0, the receiver must also be running firmware version 2.5.0.

Both must either have no binding password or have the same binding password set.

Q: How do I enter binding mode?

A: After soldering the receiver, quickly power the aircraft three times: "power on and immediately off - power on and immediately off - power on and leave on," with intervals within 1.5 seconds. If done correctly, the receiver's LED will flash quickly twice in a loop, indicating it is in binding mode. At this point, press the bind button on the transmitter script to bind. Once bound, the receiver's LED will stay lit.

Q: Why can't my receiver enter binding mode the first time I use it? The LED stays lit.

A: Through multipleAfter Sales cases, we've found that some flight controllers have abnormal TX/RX ports, causing the receiver to enter boot mode upon power-up. Simply switching to another TX/RX port on the flight controller should resolve this issue.

Q: Why is my receiver's LED flashing quickly?

A: If the receiver is powered on but not in binding mode, or if it is already bound but the transmitter is not turned on, the receiver will automatically enter WiFi flashing mode after 60 seconds of no signal, indicated by the LED flashing quickly.

Q: How do I enter WiFi flashing mode to update the receiver's firmware?

A: As mentioned above, simply power on the receiver and leave it. After about 60 seconds, it will enter WiFi flashing mode, indicated by the LED flashing quickly.

BAYCK Series Receiver RX2.4G is based on the open-source architecture and program of ExpressLRS. The receiver uses a low-latency, high-refresh-rate RF chip with a refresh rate of 25Hz~500Hz, making it ideal for FPV racing and long-range FPV. Additionally, these receivers are ultra-light and compact, making installation easier and the aircraft cleaner.
