Exactly the same as you Marwin. Same antenna setup as well. Mine just decided to not work anymore. After a flight just now, it acted as if it was unbound. Refuses to bind again. Red lights are on though so doesn't look as if it's fried.

Thanks

I fiddled around for a long time and it now works. I have no idea why it didnt work before, but thanks anyway

Flashed, and tx-rx are bind. Success!

On another topic:
Now, i need some help understanding this picture:


what is that c1 100m ?



hmm, my guess: maybe a 100nF capacitor???
It is 100uf but you are not bound to it exactly, actually on the Hobbyking unit you can get away with only using the capacitor as the resistor is already on the board itself (was given this info by Kha) My filter is simply the 47uf capacitor and it works very well indeed coupled with my Arkbird Autopilot system.

So, could someone help me out here?

I got my openLRS TX and RX in a couple days ago, and I would like to put openLRSng on them, and the more I read about it, the more I get confused..
first off, what do I need to communicate with the TX/RX? I have a USBasp that I have used for various other things that I have flashed, and when I bought the module from HK, I also got one of the little dongles for updating the module firmware. Do I need a different device?

So, I'm attempting to flash my rx with openLRSng using USBasp, and I get the following error:

Binary sketch size: 18,438 bytes (of a 30,720 byte maximum)
avrdude: warning: cannot set sck period. please check for usbasp firmware update.
avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

Any ideas? I checked the connections, and they are correct. Also I am not using the USBasp's built in 5v power, i'm powering the Rx by the servo connections.

Did you also lose control when your rssi was low or zero?

Red is not good, blue has to go on?
