Best bluetooth module for Waterproof Solar Kit

Hi, I’m complete newbie on arduino.

But I had great idea of some devices.

So I want to buy ‘Seeeduino Stalker - Waterproof Solar Kit’ with matching Bluetooth modules.

Is there anyone suggest me the Bluetooth module for ‘Seeeduino Stalker - Waterproof Solar Kit’?

Thanks in advanced.

Thanks, what is the difference between two?

Which is better for using with Arduino?
