Considering the growth in Bluetooth devices, FiveCo created a development kit for companies wishing to connect their devices rapidly thanks to this radio communication protocol.
This development kit for Microchip microcontrollers (18Fx family) comes with a code for managing the Bluetooth protocol (layer HCI up to RFCOMM, 15kBytes for ROM, 750 bytes for RAM) and has a size allowing the user to add their own code for their device.
In other words, this core gives you a virtual port com that can be used on all platforms equipped with Bluetooth (PC, Mac, Palm etc)
