I am doing a wireless rover using arduino mega 2560 that can be controlled by a smartphone and a PC. Which bluetooth module would fit me? Again I want to control it both by my Laptop(Built-in Bluetooth) and my smartphone. Thanks in advance.
A little late but in case someone like me ran into this:
HC-05 seems to be the DIY choice. Can work in slave or master mode and works with Android but not iOS.
HC-06 is the same as HC-05 except that you can only use it in slave mode.
HM-10 seems to be the option for iOS users.
