View source for Bluetooth serial modules

The bluetooth modules that are offered on ebay all seem to have the same hardware, but have different firmware. This page has some notes on the ones that we have.

==Bolutek==
Currently used in the [[Sending location information from an Android phone to a Nikon camera|GPS from Android to Nikon Camera]] project.

Initially at 9600bps, commands terminated with crlf and recognized by the following response to '''AT+VERSION''':''+BOLUTEK Firmware V2.43, Bluetooth V2.0, HCI V2.1, HCI Rev37, LMP V4, LMP SubV37''.Default name is ''Bolutek'' and default PIN is ''1234''.
