Hi,
I have a VR 2.0 and have used it with a Axon and programmed using the webbot studio.
Since you have bought the shield version. Which was made to plug into a arduino. It seems you have 3 options.
1. Buy a arduino. I believe Veear have libraries on their site. And program through Arduino.
2. Remove the VR 3.0 from the shield, plug required pins into the AxonII. ( rx, tx and power and gnd.)
3. Plug into- ( rx, tx and power and gnd.) on the VR Shield and use the Axon.
You then need to connect to the vr3.0 through usb to train voice commands using the Veear software.
After that. What I did was use webbot studio to program from there.
Not sure on your level of experience but just remember rx goes to tx and tx to rx.
