Normal rate is a little slow to avoid traffic over wireless link.

If don't arm, check arm settings and next look systemhealth for alarms

Exactly the same as previous video and skip the "PPM only" checkbox in both sides.

Setting a PPM input (flexi or mainport) in ground modem mean you want RcControl and telemetry.

Setting "PPM only" you get only RcControl without telemetry, so baudrate link is set automatically to 9600bds with an extra range because radio noise floor is lower at 9600bds.

Yes
First OPLM with PPM on one port (input from Radio) and set as coordinator: Ground side

The other with one port set as PPM for PPM output (Txpin) connected to Flexio PPMin on Nano

Like this:

Like this:

Can I use the nano's receiver input as PPMin, also pin8?
Because main port for oplink, flexi port for gpsv9. Thanks

I've just bought an oplink of banggood.
I have successfully upgraded and erased the board.
I changed the power setting and saved successfully but once I power cycle the board it refuses to stay connected.
I believe it is a windows USB issue as the board keeps appearing and disappearing as a USB device.

If windows/driver issue, try this:

After saving the change to the power setting and then power cycling the board.
I get a steady Blue light for a few seconds, then the RX/TX lights flash and the GCS briefly shows connected before disconnecting and windows beeps like it does when disconnecting a usb device.

oplink then returns to a steady blue like for a few seconds and the same happens again.

Try upgrade&Erase again

Disconnect board first
Hit upgrade&Erase button
Wait until reconnect.

If works after that, try setting with small amount of power : in some cases and hardware issues, RF can cause reboot.

I've tried this lots of times with the lowest power setting, i'm beginning to suspect a hardware issue.
