Maybe this will help:
All HC BT modules require that you set their parameters
via AT commands. You can find guides on how to do that online.
Power the module and connect to it
via a serial port. Set the required parameters.
Use another instance of serial terminal to connect via BT and
check if the loopback communication works: You type something in
on the terminal connected over BT and it appears on the terminal
connected via serial.
Only then can you be sure that your HC module is working properly.
Connect the module to the Nano and proceed as it was already
described by others.

I not remember how hc5 work, need connect and see.
About speed, exist some steps
Soft send data to BT transmiter (speed set in soft, this speed set in
NanoVNA-App). This speed can be any
BT transmiter send to hc5 over BT (speed not allow select, depend from
signal level, noise and so).
Hc5 send data to NanoVna to serial port.
This speed programmed in Hc5 and need select in NanoVna.
You can check correct hc5 work, connect rx and tx pin on it, and power on.
Use any terminal soft, send data and if all correct you receive echo (data
sended to hc5)
