Supply
power to the PP/EP1/EP2 rx, wait until the 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 LED light will start
to double-flash, which means that the RX enters the binding mode Insert
the ES24TX module or other DIY 2.4G ELRS TX to Radio transmitter, and
choose External RF mode to CRSF protocol, then you can find ELRS menu
from the Radio systems(Need to copy the ELRS.LUA file to the SD-Card
tools first), Enter into ELRS and press [Bind], the LED on the RX module
will getting to be solid if bind successfully. Receiver LED status meanings: PP
RX: 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 EP1/EP2 RX: 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)
Bind procedure: Notes: Since
the Official Perfect version of ELRS firmware has not been released
yet, currently our PP_RX, EP1/EP2 RX and ES24TX pre-loaded firmware are
all beta versions, you can upgrade the official firmware when Official
perfect target available.
