Yes, The pad you pointed out in red is where my solder bridge is. The 1st pin needs to be removed (as per original instructions) and the 3rd pin where I cut is where i installed wires for switching JR bay power on and off (switching + so that module is always grounded to board still)

Hey thegk,
So if im right we can now do the hardware mod, install the firmware and then the crossfire would work and can we change the output of the module using crsf menu in the jumper T8sg v2 +?, bcs i dont have a taranis to change that. Im basically asking if the it’s possible to change the output without a taranis. I also own the carbon version btw.

Yes, The CRSF menu works for switching power / frequency on TX and will even allow you to change number of channels and mode on your RX etc. you need to be patient with menus loading and the controls aren't 100% intuitive for selection but the key fetures i find i needed worked once i played around. you will figure it out.

Yes, just choose the option to not copy over models and before you update you should always copy your models folder as a backup in case you accidentally lose them.

I can confirm that TBS Tracer is working based on the previous CRSF support. Menu works and I was able to bind the nano RX as well as see settings for output power "My TX" etc as one would expect from the manual.

Whoever did the menu has done an excellent job - it appears to read all the new settings from Tracer and present them fine!

Seem to not be getting telemetry from BetaFlight. Battery stats missing but LQ/RSSI shows up. Telemetry enabled in BetaFlight. If I set the RxBt to be read from the rx sensor then I see a 5V value from the power to the rx in DeviationTX telemetry but nothing from BetaFlight is being shown. Sounds like it might be a Tracer/Betaflight problem but, or is there an issue seeing telemetry in Crossfire also?

Telemetry is working, blaming the first FC for this problem. Seems that using another FC has resolved that, error might be related to the first FC having a built-in SPI reciever or simply a lower-quality crazybee board.

All in all - a very good crossfire implementation which, thanks to the dynamic menus, works well for Tracer as well.
