Good for making remote for tracked Rover v2!

Great foundation for controlling tracked vehicle Rover. Implemented with Android Nexus 7 to make remote control. Eventually I will use to switch between remote control and autonomous navigation. Hope to be able to send picture files to PC and Nexus 7

Excellent module, will by another

An excellent bluetooth module. Works right out of the box but can also be reconfigured as needed. Will need this program to do so: http://180.150.162.233/en/Support/S_tools/459.html Read the datasheet provided by robotshop

Rookie

I am a rookie so it took some time to figure out the bt module. That being said, it works perfectly and a more experienced person would have had it up and running within minutes.
