Crossfire nano to Hobbywing XRotor F4 Micro Stack FC + ESC

I wired my Crossfire nano to rx & tx on uart 3
The receiver works but I do not get all of the telemetry.

Have you wired

Nano RX to uart3 TX
Nano Tx to uart RX

They have to be reversed not Tx to Tx and Rx to Rx

Have a read of this guide too.
