@renechawy: The Youtube video I linked to doesn’t work for the RP-SMA version of the Bluesmirf since the reset pin is hard-tied to GND unlike the chip antenna version. You can try sending “SF,1” to the module in command mode to reset it via software.
@kzwinn: What kind of antenna do you have on the module? Do you have any other Bluetooth devices to compare range with?
I’ve used these to at least 400 meters with a 5dbi antenna and a Host XR with a 9dbi omni at the other end. There seems to be enough link budget in this setup for perhaps a kilometer or two depending on the type of antenna used and your environment. (In my case, it was unobstructed air a few meters above a flat lake)
