i had many hard hours yrying to makes crossfire working..
If you install the micro crossfire module for the jr bay, you need to have the right power in transmitter first..
I had the 4 aa battery tray with 50% used batteres. It was not enough to powering the crossfire module.. it was making noise like a short corcuit and was always shutting down the transmitter.
So i used a 2s battery. First problem solved.
The transmitter and crossfire module need to be upgrade to the latest version..
T8sg v2 plus oled need t8sg v2 plus firmware.
T8sg v2 plus lcd need t8sg v2 firmware.
On both you need to do the 1st and 5th pin interconnection and removing the upper pin.(there is a post for this)
You need to bind the receveir to the crossfire module first. This can be done with pc and tbs agent software. You just need to powering the receiver.
Then choosing crfs protocole in transmitter.
Betaflight...... select the right protocol in configuration tab.. activate the telemetry.
Activate serial rx in ports tab on uart 6 (where my receiver is connect)
Usually it suppose to work at this step.
There is also a cli command line for rx inverted if it still no working.
It now work reallu well for me.
I also have configuration fonction for crossfire in the transmitter.
I will add info if need.
