Getting a Bluetooth stack from a *BSD operating system could be an
option, but normally these stacks are not developed with deep embedded
system in mind.
Maybe, because we are going to support only BLE (at least initially
NOTE: my assumption) we could develop a stack for scratch. I'm
suggesting it because Bluetooth Low Energy is simpler than traditional
Bluetooth stack, then it is not so complex like developing a WiFi
stack for Soft MAC support on NuttX.
Also BTstak license is incompatible with NuttX purpose and lwBT was
developed prior to Bluetooth Low Energy, then it is not supported.
Developing it from scratch we could make it suitable for
microcontrollers with few as 16KB of RAM (i.e nRF51822) and flexible
enough to support many kind of interfaces (USB, SPI, etc).
