Serial port profile spp - the serial port profile is a bluetooth profile that allows for serial communication between a bluetooth device and a host/slave device. Most modern microcontrollers and devices like the raspberry pi have at least one serial uart peripheral so you can do a lot with these devices. The secondary uart is not normally present on the gpio connector.
Obviously, if several bytes of data are arriving every 3ms, it shouldn't be a whole second before a byte is available to read. Dear Iomega.
