Hello! TDK Systems has a Bluetooth Module with an integrated BT stack and a serial interface. The module measures 69 x 20mm (about 2 x 0.75 in). With the RS232 style interface it uses modem style AT commands for commands/control and hence can be up and running working with a host in a very short space of time. It is a Class 1 preapproved device (100m range) but the antenna and great receiver we have gives us up to 200m range. Its called a blu2i module on the website. Hope that is interesting for you.
