Hi Rongzhong,
I have purchased my Bittle (pre-assembled kits) from Amazon. Although there was a $50 premium, it was the most convenient and quickest option for me.
They appear to the the SeedStudio versions (Petoi Bittle - Bionic Open Source Robot Dog (seeedstudio.com)).
However, this version that I received appears to be missing the feet-covers/socks. Unsure if it's missing any other parts too.
Is there any way you can please send me some? I can pay it it and the shipping if required.
I would like to test the Bittle behavior with and without the socks.
Can you please assist?
Thanks much in advance.
Regards
So I purchased this off bluetooth module off amazon, https://www.amazon.com/gp/product/B00WGPKZ8Y/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1, but with the little to zero knowledge about Arduino and Bittle I'm a bit scared to plug it in and try it out with the risk of permanently destroying something.
Any suggestions or guidance as if I can just plug this bluetooth module into Bittle and hook it up to my computer.
Perfect thank you for your help! I'm still learning here but I think with your advice I found one in stock on Amazon with the four ports.
All you need are Vcc, GND, Tx and Rx. I believe I went with 115.2K, 8N1. If you have the Bluetooth module breakout like one that I have, the PINs are: RTS, RX, TX, Vcc (5V), CTS, GND and it connects directly if the match up the pins in the right direction.
I happened to already have this old stuff from Sparkfun and it worked just fine:

I happen to be in the same boat as @Berndt Hamboeck I purchased off amazon through Seeed Studio and mine did not come with the socks nor the bluetooth module. I was able to buy most of the other modules off seeeds website but I could not find the bluetooth one.
A store in the future would be great!
