I have a weird problem with my RushTank Mini.

If I connect it to Betaflight with SmartAudio, everything works fine. I can change channels, power, just works. 

 I'm working now in keeping all my quads with the VTX's managed by the TBS Crossfire "My VTX" feature, but when I connect the Tank Mini vtx to my crossfire I can't choose the band or channel, it is detected as a 2.4ghz vtx and does not work.

Anyone with experience in this combination or where to contact RushFPV for support?

RushFPV does actually implement SmartAudio protocol under license from TBS and theoretically this should work.

Have said that, I have not seen anyone do this in the wild as most examples we see are using TBS VTX's being controlled via SA via the Crossfire lua script.

crossfire need a uart , and smart audio need one also , TX1 RX1 can be your crossfire uart1 , and TX3 can be your smart audio Uart 3.
Betaflight can control the vtx with stick commands
so
make sure ports are configured correctly and wired correctly, for CLI dumps, analysis and resource remapping ask Snowleopard, he's the man.

I have some rush vtx but never used myvtx

“My Vtx” only works when you have TBS Unify pro 32 or EVO vtx and I am almost certain you have to have a XF nano RX also.


You can use S.Audio with your FC then use sticks or betaflight lau scripts to control all the Vtx settings.

I tried using “My Vtx” and found out it only works with certain TBS vtx.
It comes in handy for FPV with planes or cars that don’t have FC ie S.Audio.

For the record, I finally managed to make it work. Now I have my Rush Tank Ultimate Mini VTX manage by Crossfire RX with "myVTX" feature.

I'm not sure what was the fix, but troubleshooting I realized that if I disabled the MyVTX feature and changed the configuration in the XF RX module it worked fine. 
In a last attempt, I first configured the Channel, Band and Power from the "XF RX" and then activate the MyVTX feature with the same configuration and, to my surprise, It started working.

Thanks for the confirmation. Good to know this does work.

I did mention in a very early reply that I had not seen an example working. Atleast we now have a working proof of concept.
