Bind Procedure:
- Supply power to the EPW5 RX, wait until the Green LED on the RX is off, immediately turn off the power, and then repeat again the above steps. When the RX is powered on for the third time, the Green LED light will start to double-flash, which means that the RX enters the binding mode
- Get into menu of ELRS.LUA V2.0 version from your radio transmitter and then press BIND, the Green LED on the RX module will getting to be solid if bind successfully.
Receiver LED status meanings:
LED solid means bind successful or Connection established; LED double-flash means in bind mode; LED flash slowly means no signal connection from the TX module; LED flash fast means in WIFI hotspot mode, you can connect the WIFI of the RX and upgrade firmware of the RX via visit 10.0.0.1 from the web browser(password: expresslrs)
Binding seem to be successful. After connecting the battery the led triple-flashes, but there is no reaction on Tx commands. If I disconnect the battery, Tx tells telemetry lost. can you please explain what is going wrong, thank you
