Crossfire nano to Hobbywing XRotor F4 Micro Stack FC + ESC

Help
#1

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

#2

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

#3

Have a read of this guide too.
