Hi all,

It seems that a pair of bluetooth modules can be used for telemetry, while OPLinks are also needed for vehicle control.
I am wondering is it possible to realise vehicle control and telemetry only (by mobile phone) through bluetooth? Leaving OPLinks omitted.

Hi, possibly you can, but the range of flying would be very limited, like 20m max.
Is that what you want?

Thank you first.

Yes, I am a newbie and haven't own a radio yet, short distance control trial will fit me now.

When using bluetooth, is the connection like neither:
GCS(on Linux or Windows)->FTDI_USB_to_TTL->HC-06 --------> HC-06->RevoBoard,
or,
Libre2Go App(on Android)->FTDI_USB_to_TTL->HC-06 --------> HC-06->RevoBoard?

The hardware setup would be the same as for simple bluetooth telemetry.  Get that working first.

Then there is some setup to e.g. use a joystick on the GCS to fly the aircraft.  I have never done that though.

Libre2Go do not have GCS Control function like GCS using Linux, Windows, Mac have.
Connection would be more simple I think, like this
GCS (Linux,Windows,Mac)  -> built in Bluetooth unit --------> HC-06->RevoBoard.

@TheOtherCliff Thanks, it's a good reference!

@karla My laptop doesn't come with a bluetooth . Thank you all the same~

If it has USB, then there are cheap USB to Bluetooth adapters.  I just bought one for USD $3.15 shipped and it arrived in 11 days.  The one I bought ?seems to? only come with Microsoft Vista and Win7 drivers, but my Linux Mint 17 saw it and used it with built in drivers.  Edit: The package says Windows 8 and Windows 10 on it.  The file timestamps are in 2012.

Yes, it has USB.
But my friend suggests me to have one RC for long-term use purpose. Then I searched and found somebody in the neighborhood selling one RC of his.  ;DSo finally, I received it today. That is a Frsky Taranis Q X7 without receiver.

Thank you again.

(Although no receiver with it, an external oplink module can perform as one, I thought. If any problem occurs, I will post it in other topic.)
