Hello! i have bouth a radiomaster micro, with the EP1 reciever, i flashed and everything connects just fine, but when i go to the bfconfigurator it doesn't have any stick inputs, i alredy tried re-flashing the tx and rx, changing the uarts, de-inverting the ports (rx -> rx, tx -> tx), and still nothing, any ideas?

Your wiring is correct, but my first observations are that the soldering looks a bit dodgy TBH (possible bad connections and/or dry joints). Before doing anything else I would resolder all the wires between the receiver and the FC. Make sure you are using plenty of additional flux and that you are using good quality leaded solder (not the lead-free rubbish or some Chinese no-name brand) which has a tin to lead ratio of 60/40 or 63/37.

After doing that, use a multimeter in continuity (beep) mode to make sure you have no short circuit between any two of the TX, RX, 5V and GND connections.

When flashing ExpressLRS firmware to the EP1 receiver, make sure you have both the "RCVR_UART_BAUD" and "RCVR_INVERT_TX" unticked.

With your transmitter powered off, does the LED on the receiver start flashing and only turn a constant colour when you then turn on your transmitter?

Can you please also run both the "dump" and "diff all" commands in the Betaflight Configurator CLI tab and copy/paste the results back here.

They are fine for what i see

Yes it is like that

Starts flashing then connects

i don't know if it is relevant, but earlier i had a frsky reciever (that binds directly to the radio)

All of your Betaflight settings look fine.

On your transmitter, go to the CHANNEL MONITOR page and check to see if the bars on that screen move when you move the sticks. If that is OK then try wiring the ELRS receiver to a different UART on the FC, and if that still doesn't work then either try that ELRS receiver on a different FC (if you have a spare one) or try a different ELRS receiver on that FC (again, if you have a spare one).

It works! I changed the Bauds to 400k in the configurator(the wifi page), and now it connects, it just ain't showing tellemetry now, im going to fly with it a little to see if the link is ok
