FrSky R-XSR Receiver: No input? No Channel Band Movement in Betaflight? 

5 years later and this video is still helpful :) Finally the tip (that I needed) that everyone else misses.

How do u get rssi?

I'm stumped. I updated the rsxr firmware. I bound it to my radio before I installed it. I installed it in a Tinyhawk 2 that was getting CALIB flag using the onboard SPI receiver and it would fall out of the sky. So the Tinyhawk seemed to have more problems because the motors stopped spinning up, it began to only connect to Betaflight sometimes when I would plug it in, but I got light flashes when I would arm and in Betaflight the receiver was working. I took the RXSR off the Tinyhawk and just ordered a new FC for the TH. So I installed the RSXR in my first build. A Succex f4 V2.1 16x16 stack. I wired it as you showed here. I have it in the correct places on the FC, but when I plug a battery into the quad there are no lights on the RSXR. No lights, no movement in Betaflight in the receiver tab. I took the receiver off and plugged into a 5v 1.5a power supply and the lights light up as they should. Plug it back into the quad and nothing. I thought maybe I have a bad solder joint even though they look good. I desoldered the 3 wires and soldered them back to the FC and still no lights on the receiver. Also strange, plugging a battery into the quad will give me all the start up tones except for the last 2. If I have it plugged into the computer/Betaflight and then plug a battery in, I get all the tones. I can spin the motors up in Betaflight, but no receiver. Do you have any idea what this could be? I'm going nuts here. I've broken the flight controller on my Tinyhawk 2. I broke the frame and one motor on my Tinyhawk Freestyle 2. I have this beautiful 3 inch Tadpole with a nice stack, Xing 1404 4600kv motors, a beautiful day that is slipping away, and rain in the forecast for tomorrow. I even used the smoke stopper you recommended just to make sure I didn't blow anything up.

HI MY BETAFLIGHT IS ALL UP TO DATE BUT THE RECIEVER SECTION COMES IN BLANK PLZ HELP ME ASAP

Sir,how to connect it to transmitter

I had the same problem.... my fix was that the RXSR was in PWM mode and not SBUS... pulled my hair out for 2 hours before I decided to RTFM instead of going on YT videos alone. Switched the RXSR to SBus mode and...Problem solved.

Can u pit these drone making tritoral

If anyone knows plz replay

I bought a BNF and flew it once. I ripped off the antennas to the r-sxr and now it won’t arm or show imputs in Betaflight. But it shows signal on On the R-axr and my Taranis.. what did I do to it?

check, check, check but not the piece of paper that came with the receiver.. lol..

Thank you so much John, I've been scratching my head for few hours trying to figure out what went wrong with my 1st r-xsr receiver until I saw you video, it's a freaking simple mistake lol. Thank you so much!

Glad to see I'm not alone. Thanks for posting this. I had just about given up hope of ever getting this quad in the air. I was one happy guy tonight when my first build flew great! Thanks again!

THANKYOU , So easily missed when the box arrives in the mail and you just want to get in the air !!! great explanation also

You are absolutely wonderful!!!

Thank you!!!

Thank you....spent hours trying to figure this out...works great now!!!

I spent a few days updating firmware and the issue was this simple...thank you!

I just want to thank you for this vid...I was losing my mind of this damn receiver. Saw the instructions, but just did not put 2 and 2 together. You saved my sanity, seriously.

It took me about 5 hours to find this, so glad I made it here, you're a legend!

I knowed that I miss something when saw instructions, but omg. Thank you!
