I have a PS3 controller connected to an arduino board through a bluetooth shield. Is there any way that I would be able to extract RSSI information from the module (the conection is: PS3 Controller -> cheap usb bluetooth donge -> usb shield -> arduino)? Also, I am willing to place another bluetooth module at another location (most probably HC05) and grab RSSI information from that module as well. Is this possible at all? Is there any way for the HC05 to get RSSI data without being connected to the PS3 controller? I am aiming for some form of Relative Indoor Positioning System IPS.
