Got a tbs crossfire system (micro tx + micro rx v2) today and I'm having a few issues with it. I wired in my crossfire micro rx v2 correctly, with CH1 to rx etc, and I bound the receiver to my qx7s fine (did also adjust the baud rate). I can configure the receiver from the radio and I do get RSSI feedback so I know its working. However, I don't get any stick inputs in betaflight? I've wired it up to tx6/rx6, set serial rx on for that uart. Set the protocol as CRSF in betaflight and the radio. The micro tx is also set to output CRSF TX to rx and CRSF RX to tx correctly. I've updated firmware for the transmitter/receiver and nothing still. Also tried doing it with a LiPo plugged in and nothing. Help please! If it helps, I have an emax buzz and here's the flight controller diagram: https://emax-usa.com/download/Buzz_I...anual_v1.3.pdf Thanks so much in advance! ![[-]](https://intofpv.com/images/collapse.png) • Posts: 1,312 Threads: 50 Likes Received: 832 in 504 posts Likes Given: 372 Joined: Jul 2018 Reputation: 51 Did you create a model in your QX7? You might need to redo your mixer settings again.

I've used the same model as I've always done, which worked on my R9M and xm+, would I need to create another model? • Posts: 1,312 Threads: 50 Likes Received: 832 in 504 posts Likes Given: 372 Joined: Jul 2018 Reputation: 51 (20-Mar-2020, 04:10 PM)damajesticmuffin Wrote: I've used the same model as I've always done, which worked on my R9M and xm+, would I need to create another model? If you changed an existing model to use Crossfire then you shouldn't need to set up the channels and mixer again. Could you post a dump from the Betaflight CLI?

Could you post a dump from the Betaflight CLI? It didn't let me post all of it because too many characters so I had to make a google document instead, sorry https://docs.google.com/document/d/1AxAP...sp=sharing • Posts: 1,312 Threads: 50 Likes Received: 832 in 504 posts Likes Given: 372 Joined: Jul 2018 Reputation: 51 Hmm, your config looks fine.
Is it definitely wired to UART6? I couldn't see any pads for it, unless you're stealing the wires from the VTX header?

The plug that the crossfire came with had pins inside the header which also fit into the vtx header plug, so I took the individual pins out and put them in there. I did the same with my R9MM and it worked (however I did solder the wires together, not put the pin inside the header for the r9mm) • Posts: 21,190 Threads: 582 Likes Received: 8,930 in 6,606 posts Likes Given: 1,425 Joined: Jun 2018 Reputation: 786 Your problem is that you've re-mapped the original resource (C07) for "SERIAL_RX 6" to "SERVO 1". So you no longer have a full RX/TX functionality on UART6. Is there any reason you've done that? Are you trying to use a servo for something? Quote:# resources

Thank you both! You're both lifesavers and I don't know what I would do without this website!!!

I went through the CLI dump but everything seems fine. Can you please check over my CLI dump to see if you can spot something? I have the Crossfire Nano RX set to UART3 and wired to RX3 and TX3 on a XILO F4 board. Thanks in advance  here is the CLI dump since it's too long to post on here https://docs.google.com/document/d/16qNA...sp=sharing Posts: 21,190 Threads: 582 Likes Received: 8,930 in 6,606 posts Likes Given: 1,425 Joined: Jun 2018 Reputation: 786 (16-Aug-2020, 07:08 PM)THEGEEK19 Wrote: Hey guys, I'm having a similar issue.

Worked like a charm. Thank you so much for the quick reply! |
