Why won’t my ExpressLRS receiver bind to the transmitter?

Question: Why won’t my ExpressLRS receiver bind to the transmitter?

Answer: First, ensure both your transmitter and receiver are running the same ExpressLRS firmware version and protocol settings. Check that the receiver is powered correctly, typically 5V or as specified, and that the binding button or pad is pressed or shorted while powering it on to enter bind mode. On the transmitter, make sure you select the correct module type and enter bind mode. Keep the transmitter and receiver close (within 1 metre) during binding to avoid signal loss. If binding fails, verify the antenna connections on both devices are secure and undamaged. Also, confirm that the receiver is not already bound to another transmitter; if so, perform a factory reset or rebind procedure. Finally, consult the ExpressLRS documentation for your specific hardware, as some receivers require specific steps or jumper settings to enable binding. Following these steps should resolve most binding issues.
